Description

The present invention relates to a software development man-hour estimation device and a software development man-hour estimation program for estimating software development man-hours used for realizing a service requested by a user.

  When receiving a request from a company providing a service and developing software that implements the service provided by the company, a standard software package must be developed in advance and customized. By doing so, a method of developing software required by the company is used.

  In such a case, it is necessary to estimate the software development man-hour by estimating the man-hour required for the customization.

  Until now, the estimation of software development man-hours has been left to the experience of the designer who develops the software.

  On the other hand, in order to estimate the software development man-hours, it is necessary to measure the size of the software. As a method for measuring the scale of software, a method of counting the number of lines of a program (LOC method: Lines of Code) and a method of counting functions of software (FP method: function point method) are known.

  Since it is possible to measure the scale of software by using these methods, the number of software development man-hours is also estimated by using these methods.

  However, the estimation of software development man-hours using the LOC method and FP method that has been performed so far is for newly developed software, not for modifications of already developed software. .

  From now on, according to the conventional technology so far, when developing a software package that becomes a standard by developing a standard software package in advance and customizing it, when using the method There is a problem that development man-hours cannot be estimated automatically.

With such a background, an invention is disclosed in which, when existing software is reused, an estimation is performed using the FP method (see, for example, Patent Document 1).
JP 2005-266987 A

  As a method for measuring the scale of software, the FP method is used more than the LOC method.

  This is because the development method is shifting from the procedure (code) description base to the visual development tool base at the program level while the software development form is moving from the mainframe to the client server.

  However, when determining the specifications of the software to be developed by meeting with the user, what kind of business function the user requires rather than the function that is the basis for calculating the software scale handled by the FP method Software development man-hours will be greatly affected by whether or not

  From now on, when developing a standard software package in advance and customizing it to develop the software required by the user, the LOC method is used rather than the FP method. It is considered appropriate to estimate the software development man-hours.

  However, the estimation of software development man-hours using the LOC method performed so far is for newly-developed software, and is not for remodeling already-developed software.

  The present invention has been made in view of such circumstances, and uses a method of developing software required by a user by developing a standard software package in advance and customizing it. In this case, an object of the present invention is to provide a new software development man-hour estimation technique that can automatically and accurately estimate the software development man-hours requested by the user.

  When deciding on the scale of software modification, it is easier to determine the scale of the modification without considering the size of the software matrix, rather than determining the scale of the modification based on the scale of the software. is there. However, the accuracy is inferior because the size of the software matrix is not considered. Therefore, the storage means stores information on the modification scale determined without considering the software matrix size, and the estimation means corrects it using the software matrix size.

  Here, each of the processing means described above can be realized by a computer program, and this computer program is provided by being recorded on an appropriate computer-readable recording medium or provided via a network to implement the present invention. In this case, the present invention is realized by being installed and operating on a control means such as a CPU.

  In the software development man-hour estimating device of the present invention configured as described above, it is described in a form corresponding to a series of business function information executed by each of a plurality of services prepared in advance, and which service is requested by the user. If you enter information that describes whether it is a business function that needs to be remodeled or not, the user requests it by analyzing the entered information In order to realize a service, it is possible to detect which business function executed by the service needs to be modified.

  Based on the input information, it is necessary to detect which business function that is executed by the service needs to be modified in order to realize the service requested by the user, and to detect the detected service / business function.

  Moreover, since software development man-hours are estimated on the assumption that software development will be performed in the form of modification of software that has already been developed, the software man-hours used to realize the services required by users are highly accurate. Can be estimated.

  Here, in the case of following the first invention described above, the user only has to input which service item is to be modified for the service requested by the user. Since some of the business functions that provide the services are not executed by the service requested by the user, the accuracy of estimating the software development man-hours is not sufficient.

  On the other hand, in the case of following the second invention, the user understands a series of business functions executed by the service for the service requested by the user, and modifies which business function from among them. However, it takes a lot of time and effort to input, but only the business functions executed by the service requested by the user are extracted and estimated, so the software development man-hours are highly accurate. Can be estimated.

[3] Third invention In order to achieve the above-mentioned object, the software development man-hour estimation device of the present invention provides a service requested by a user when software used for realizing a plurality of services is prepared in advance. In order to realize the estimation of the development man-hours of software used to realize the (1) What are the forms created by the business functions for the business functions executed by a plurality of services prepared in advance?

It is configured to include an estimation unit that acquires information on the scale of software modification necessary for the software and estimates the number of software modifications based on the information.

  When adopting this configuration, the estimation means may process the software modification scale information obtained from the storage means corrected by the base scale of the software so as to estimate the software modification effort. is there.

  When deciding on the scale of software modification, it is easier to determine the scale of the modification without considering the size of the software matrix, rather than determining the scale of the modification based on the scale of the software. is there. However, the accuracy is inferior because the size of the software matrix is not considered. Therefore, the storage means stores information on the modification scale determined without considering the software matrix size, and the estimation means corrects it using the software matrix size.

  Here, each of the processing means described above can be realized by a computer program, and this computer program is provided by being recorded on an appropriate computer-readable recording medium or provided via a network to implement the present invention. In this case, the present invention is realized by being installed and operating on a control means such as a CPU.

  In the software development man-hour estimating device of the present invention configured as described above, which form is described in association with the information on the creation conditions of the form created by a plurality of services prepared in advance, and which form is requested by the user And if you enter information that describes which of the creation conditions of the form you need to modify, you can create the form requested by the user by analyzing the entered information Therefore, it is possible to detect which preparation conditions of the form need to be modified.

  From now on, based on the input information, in order to realize creation of the form requested by the user, it is detected which creation condition of the form needs to be modified, and the detected form / form creation condition is detected. By referring to the storage information of the storage means using the information as a key, listing information on the scale of software modification required to create the form requested by the user, and accumulating them, Information on the scale of software remodeling necessary for realizing the creation of a form requested by the user is obtained, and the man-hour for software remodeling is estimated based on the information.

  In this way, according to the software development man-hour estimation device of the present invention, what kind of form is requested based on the information on the form creation conditions created by a plurality of services prepared in advance by the user, and the form By simply entering which of the creation conditions needs to be modified, it will be possible to estimate the software development man-hours used to create the form requested by the user. It will be possible to automatically estimate the development man-hours of software used to create the requested form.

  Moreover, since software development man-hours are estimated on the premise of developing software in the form of remodeling software that has already been developed, the number of software development man-hours used to realize the creation of forms requested by users is reduced. It becomes possible to estimate with high accuracy.

  Here, in the third aspect of the invention, the form requested by the user is specified, and the estimated form is used for estimation, so that the form requested by the user can be created in the same manner as in the second aspect described above.

  According to the present invention, when a method of developing software requested by a user by developing a standard software package in advance and customizing the package, the software requested by the user is used. Development man-hours can be estimated automatically and with high accuracy.

  Hereinafter, the present invention will be described in detail according to an embodiment applied to estimation of software development man-hours for constructing a system for a leasing business.

  In addition to the leasing business, companies that run the leasing business often run various businesses such as rental business, installment business, payment consignment business and maintenance agency collection business. Also in the leasing industry, when leasing alone, in the case of leasing in the form of opening company names in cooperation with multiple companies, or in the form of blinding company names in cooperation with multiple companies There are various forms, such as when leasing at the same time, and there are also various forms such as becoming a managing company or a non-secretary company when leasing with open cooperation or blind cooperation.

  Software development companies are required to develop software for constructing a system for the leasing business from a company operating such a leasing business.

  In order to cope with such demands, software development companies have developed software packages that are standard for the leasing industry in advance and customized them to meet the demands of companies operating the leasing industry. We are trying to develop software that is used to build a system.

  FIG. 1 illustrates an embodiment of a software development man-hour estimation device 1 according to the present invention that realizes the estimation of software development man-hours necessary for such software development.

  As shown in this figure, the software development man-hour estimation device 1 of the present invention uses a lease product definition check sheet 100 to estimate the software man-hours used to construct a system required by a company operating a leasing business. As inputs, a modeling remodeling step file 10, a remodeling work man-hour estimation file 11, an input unit 12, a leased product definition analysis unit 13, a leased product definition analysis result storage unit 14, a remodeling work man-hour estimating unit 15, The result storage unit 16 and the estimation result output unit 17 are provided.

  In the lease product definition check sheet 100, what kind of leasing service is realized by the standard software package developed for the leasing industry, and what service items are realized in the leasing service? This leasing product definition check sheet 100 is distributed, for example, in the form of electronic data to a company engaged in a leasing business requesting an estimate of software development man-hours. What kind of software the company needs by filling out and collecting information about whether the service is the target of the estimate and which service items need to be changed in those leasing services Prepared to get information on what is .

  FIG. 2 shows an example of the data structure of the leased product definition check sheet 100.

  The lease product definition check sheet 100 shown in this figure is a contract type name (which corresponds to the type of the lease business service) that can be handled by a company that operates the lease business. (A) in the figure, an estimate availability check mark entry field (α in the figure), which is an entry field as to whether or not the product definition (lease service) of the contract type is to be estimated. A product definition number of the contract type, a list of product items (index numbers are assigned) that may be provided in the product definition of the contract type, and associated with those product items Whether the software part of the product item provided in the standard software package needs to be changed. It describes the customization check mark entry column as the entry column of Te (beta shown in the figure).

  For example, in the standard software package that realizes the product definition of lease (single), the sales evaluation target with the index number “01”, the profit calculation target with the index number “02”, and the fixed index number “03” Product items such as asset declarations are described as being realized by recording “Y”, and product items such as fixed asset declaration settlement category (solid settlement settlement category) with index number “04” In addition to describing that “−” is essentially unnecessary by recording “−”, a blank customization check mark entry field is described in association with those product items.

  Note that “a”, “b”, “c”, “d”, and the like are described in the sales accounting standards, etc., and these are for identifying the various methods in the sales accounting standards. In addition, what these product items mean is explained separately.

  When a company engaged in a leasing business requesting an estimate of software development man-hours is distributed with such a leased product definition check sheet 100, an estimate availability check mark entry field provided in association with the product definition to be estimated In addition to filling in the check mark in the check box for customizing that is provided in association with the product item that needs to be changed among the product items provided in the product definition to be estimated, Information on what kind of software the company needs is written and notified to the software development company of the distribution source.

  In addition, since the product item for which “-” is recorded in the leased product definition check sheet 100 is a product item that is not essentially necessary, in the normal case, the product item for which this “-” is recorded. It does not happen that a check mark is entered in the check mark entry field for customization. Further, although not described in the leased product definition check sheet 100 shown in FIG. 2, “N” indicating that the product item is not realized may be described in addition to “Y” and “−”. .

  Next, the modeling modification step file 10 will be described.

  The modeling remodeling step file 10 manages, for each business function executed in the product definition, information on which product item in which product definition the business function is to be executed, and the business function. Manages information about the scale of software remodeling required when making changes.

  FIG. 3 shows an example of the data structure of the modeling modification step file 10.

  As shown in this figure, the modeling remodeling step file 10 manages the product definition number and the index number of the product item in association with the business number for each business function executed in the product definition. Manages information about which product item in which product definition the function is to be executed, and associates the product definition number and product item index number with the scale of software (program) modification By managing the number of steps, information on the scale of software modification required for changing the business function is managed.

  For example, for the business function “Customer management”-“Business partner management”-“Group registration / modification” with the business number “3”, the product definition with the product definition number “S5501L00” (as shown in FIG. 2). Management that the product item with the index number "25" (product item called cost accounting standard and depreciation expense a as shown in Fig. 2) At the same time, it is managed that the scale of software remodeling required for changing the business function is 200 steps.

  Next, the modification work man-hour estimation file 11 will be described.

  The remodeling work man-hour estimation file 11 is prepared as a work area of the remodeling work man-hour estimating unit 15 and is used for recording data obtained while the remodeling man-hour estimating unit 15 proceeds with the processing.

  FIG. 4 shows an example of the data structure of the modification work man-hour estimation file 11.

  As shown in this figure, the remodeling work man-hour estimation file 11 associates each business function executed in the product definition with its business number (the same as the business number managed by the modeling remodeling step file 10), Manages the information on the number of screens / forms possessed by the software that implements the business function and the information (step number) of the base size of the software that implements the business function, and as a work area for the remodeling work man-hour estimation unit 15 , A recording area for recording the number of steps of the remodeling scale (0 is recorded as the initial value), a recording area for recording the number of steps of the new conversion scale (0 is recorded as the initial value), and the man-hours for the remodeling And a recording area for recording the number of steps.

  FIG. 5 illustrates an example of a processing flow executed by the leased product definition analysis unit 13, and FIGS. 6 and 7 illustrate an example of a processing flow executed by the remodeling work man-hour estimation unit 15.

  Next, processing executed by the software development man-hour estimating device 1 of the present invention configured as shown in FIG. 1 according to these processing flows will be described in detail. First, processing executed by the leased product definition analysis unit 13 will be described.

  When the leased product definition check sheet 100 is collected from a company engaged in the leasing business, the leased product definition analysis unit 13 firstly, as shown in the processing flow of FIG. Enter. Note that the processing of this step S10 is not actually executed by the leased product definition analysis unit 13, but is executed by the input unit 12.

  Subsequently, in step S11, when it is determined whether or not all the product definition numbers described in the leased product definition check sheet 100 have been selected, and when it is determined that all the product definition numbers have not been selected, Proceeding to S12, one unselected product definition number is selected according to the order from the top product definition number.

  Subsequently, in step S13, the selected product is determined by determining whether or not a check mark is entered in the quotation availability check mark entry field (entry field in the α portion in FIG. 2) indicated by the selected product definition number. It is determined whether or not the product definition of the definition number is a target for estimation.

  When it is determined that the product definition of the selected product definition number is not subject to estimation according to this determination processing, the processing returns to step S11. On the other hand, when it is determined that the product definition is subject to estimation, the processing returns to step S14. Then, the selected product definition number is recorded in the lease product definition analysis result storage unit 14.

  Subsequently, in step S15, an initial value 1 is set in the variable i, and in a subsequent step S16, a customizing check mark entry field indicated by the index number i of the selected product definition number (an entry field in the β portion in FIG. 2). Check whether a check mark is entered in.

  Subsequently, in step S17, it is determined whether or not it is detected that a check mark has been entered in accordance with this check process, and when it is detected that a check mark has been entered, the process proceeds to step S18, where The number i is recorded in the leased product definition analysis result storage unit 14 in association with the selected product definition number. On the other hand, when it is detected that the check mark is not entered, the process of step S18 is omitted.

  Subsequently, in step S19, the value of i is incremented by one. In the subsequent step S20, it is determined whether or not the value of i exceeds the maximum value imax of the index number, and does not exceed the maximum value imax. Is determined, the process returns to step S16. On the other hand, when it is determined that the maximum value imax has been exceeded, the process returns to step S11.

  Thus, when it repeats the process of step S11-step S20, when it is judged in step S11 that all the product definition numbers described in the lease product definition check sheet 100 are selected, the process ends. To do.

  In this way, when the leased product definition check sheet 100 is collected from the company that operates the leasing business, the leased product definition analysis unit 13 determines which product definition is to be estimated based on the entry on the leased product definition check sheet 100. And which of the product items provided in the product definition needs to be changed, and the extracted information is recorded in the lease product definition analysis result storage unit 14 It is processed like this.

  Next, processing executed by the remodeling work man-hour estimation unit 15 will be described.

  When the remodeling work man-hour estimating unit 15 is started when the leased product definition analyzing unit 13 finishes the process, first, as shown in the processing flow of FIG. 6, the leased product definition analyzing result is stored in step S30. In accordance with the order from the first product definition number recorded in the section 14, an unselected product definition number is selected, and in the subsequent step S31, an index number (which indicates a product item) is associated with the selected product definition number. ) Is recorded.

  Subsequently, in step S32, it is determined whether or not it is detected that an index number is recorded in accordance with this check process, and when it is detected that no index number is recorded, the process proceeds to step S33 to select The information indicating that it is not necessary to modify the software that realizes the product definition of the product definition number is recorded in the estimation result storage unit 16, and the process returns to step S30.

  On the other hand, when it is detected that the index number is recorded in association with the selected product definition number according to the determination process in step S32, the process proceeds to step S34, and the remodeling man-hour estimation file 11 is copied. The modification work man-hour estimation file 11 for the product definition of the selected product definition number is created, and the initial value 0 is written in the recording area of the modification scale of the file.

  Subsequently, in step S35, one unselected index number is selected according to the order from the first index number recorded in association with the selected product definition number. Subsequently, in step S36, the number of steps of the modification scale is specified by referring to the modeling modification step file 10 using the selected product definition number and index number as a key, and the number of steps of the specified modification scale is modified. Cumulatively add to the remodeling scale recording area of the man-hour estimation file 11.

  For example, if the selected product definition number is “S5501L10” for “lease (open cooperation / secretary)” and the selected index number is “11” for “cooperative collection category”, “S5501L10” and “11” By referring to the modeling remodeling step file 10 having the data structure shown in FIG. 3 using as a key, the remodeling scale of 330 steps recorded in the business number “7” and the business number “27” are recorded. When the modification scale of 1300 steps and the modification scale of 5500 steps recorded in the work number “28” are specified and the initial value 0 is recorded in the modification scale recording area of the modeling modification step file 10 For example, as shown in FIG. 8, 330 steps are stored in the recording area of the modification scale of the work number “7” of the modification work man-hour estimation file 11 as the cumulative addition value. Record, record the modified 1300 steps in a recording area of the scale of the business number "27" is to process the recording region of the modified scale to record 5500 Step business number "28".

  Subsequently, in step S37, it is determined whether or not all index numbers recorded in association with the selected product definition number are selected, and when it is determined that all index numbers are not selected, Returning to the process of step S35, on the other hand, when it is determined that all index numbers have been selected, the process proceeds to step S38, where all the product definition numbers recorded in the lease product definition analysis result storage unit 14 have been selected. Judge whether or not.

  When it is determined that all the product definition numbers recorded in the leased product definition analysis result storage unit 14 are not selected according to this determination process, the process returns to the process of step S30, while the leased product definition analysis result storage unit 14, when it is determined that all the product definition numbers recorded in 14 have been selected, the process proceeds to step S39 to estimate the software required for the modification for the software that implements the product definition for which the modification work man-hour estimation file 11 has been created. Then, the estimation result is output and the process is terminated.

  Next, details of the processing executed in step S39 will be described according to the processing flow shown in FIG.

  When the remodeling work man-hour estimation unit 15 enters the process of step S39, first, as shown in the process flow of FIG. 7, first, in step S390, the remodeling work man-hour estimation file 11 (in the product definition number) is created. One of the unselected modification man-hour estimation files 11 is selected from those created based on the above.

  Subsequently, in step S391, the initial value 1 is set to the variable j, and in the subsequent step S392, the number of steps recorded in the recording area of the modification scale indicated by the work number j included in the selected modification work man-hour estimation file 11 is set. In the subsequent step S393, it is determined whether or not the read modification scale step number indicates a non-zero value.

When it is determined in accordance with this determination processing that the read modification scale step number indicates a non-zero value, the process proceeds to step S394, and the parent scale record indicated by the job number j of the selected modification work man-hour estimation file 11 is recorded. Read the number of steps of the maternal scale recorded in the area,
Number of new conversion scale steps = ((number of remodeling scale steps / number of parent scale steps) + 1)
× (number of scale steps)
Calculate the number of steps of the new conversion scale according to the formula:
Remodeling man-hour = New conversion scale steps / 1000
However, the modification man-hours are calculated according to the calculation formula of 1000: 1 man-month steps, and the calculated values are recorded in the corresponding recording area of the selected remodeling man-hour estimation file 11.

In the example shown in FIG. 8, according to 330 steps recorded in the remodeling scale recording area of the work number “7” of the remodeling work man-hour estimation file 11,
New conversion scale step number = ((330/2000) +1) × 330≈384
And based on that,
Remodeling man-hour = 384/1000 ≒ 0.38
And the calculated values are recorded in the corresponding recording area of the selected modification man-hour estimation file 11.

  On the other hand, when it is determined that the read modification scale step number indicates 0 according to the determination process of step S393, the process of step S394 is omitted.

  Subsequently, in step S395, the value of j is incremented by one, and in the subsequent step S396, it is determined whether or not the value of j exceeds the maximum value jmax of the business number, and does not exceed the maximum value jmax. Is determined, the process returns to the process of step S392.

  On the other hand, if it is determined in step S396 that the value of j has exceeded the maximum job number jmax, the process proceeds to step S397 to be recorded in the modification man-hour recording area of the selected remodeling man-hour estimation file 11. The total number of remodeling man-hours is calculated, and the calculated value is recorded in the estimation result storage unit 16 in a form corresponding to the product definition number that is the creation source of the selected remodeling man-hour estimation file 11.

  Subsequently, in step S398, it is determined whether all the remodeling work man-hour estimation files 11 created in step S34 are selected, and when it is determined that all the remodeling man-hour estimation files 11 are not selected, Returning to the process of step S390, when it is determined that all the modification work man-hour estimation files 11 have been selected, the process proceeds to step S399, the estimation result recorded in the estimation result storage unit 16 is output, and the process ends.

  That is, a list of paired data of the product definition number of the product definition to be estimated and the total remodeling man-hours for the software that realizes the product definition recorded in the estimation result storage unit 16 is output and processed. It ends.

  Note that the processing in step S399 is not actually executed by the remodeling work man-hour estimating unit 15, but is executed by the estimation result output unit 17.

  In this way, the software development man-hour estimation device 1 of the present invention configured as shown in FIG. 1 distributes a lease product definition check sheet 100 to a company that operates a leasing business, and fills in a check mark. By simply having it done, processing is performed so as to estimate the software development man-hours used to construct the system required by the company. Note that the lease product definition check sheet 100 may be filled in by a software development company having a meeting with a company engaged in the leasing business.

  FIG. 9 shows another embodiment of the software development man-hour estimating device 1 of the present invention.

  The software development man-hour estimation device 1 of the present invention configured as shown in FIG. 1 is required to realize a system required by a company operating a leasing business from the viewpoint of a product item provided by a product definition (lease business service). The scale of software modification is specified, and the software development man-hour is estimated based on it.

  From this point of view, it is possible to estimate the software development man-hours by using the leased product definition check sheet 100 configured as shown in FIG. However, the accuracy of the estimation of software development man-hours may not be sufficient because the viewpoint of the work flow for executing the product definition is not included.

  Therefore, the software development man-hour estimation apparatus 1 of the present invention shown in FIG. 9 specifies the scale of software remodeling required for realizing the system required by the company operating the leasing business from the viewpoint of the flow of work for executing the product definition. Based on this, the software development man-hour is estimated.

  The software development man-hour estimation apparatus 1 of the present invention shown in FIG. 9 performs modeling using the process definition check sheet 200 as an input in order to estimate the software development man-hour used to construct a system required by a company operating a leasing business. A remodeling step file 20, a remodeling work man-hour estimation file 21, an input unit 22, a process definition analysis unit 23, a process definition analysis result storage unit 24, a remodeling man-hour estimation unit 25, and an estimation result storage unit 26; And an estimation result output unit 27.

  In this process definition check sheet 200, the standard software package developed for the leasing industry realizes what kind of leasing service, and further, the leasing industry service realizes the service according to what business function flow. The process definition check sheet 200 is distributed, for example, in the form of electronic data to a company engaged in a leasing business requesting an estimate of software development man-hours. By filling in and collecting information on whether the leasing business services are to be estimated and which business functions need to be changed in the flow of business functions executed in those leasing business services, What kind of software the company needs It is prepared to get the broadcast.

  FIG. 10 illustrates an example of the data structure of the process definition check sheet 200.

  The process definition check sheet 200 shown in this figure is composed of a process definition check sheet header part 200a and a process definition check sheet main body 200b. The process definition check sheet header part 200a is likely to be handled by a company operating a leasing business. In association with a contract type name, an estimate availability check mark entry field (α in the figure) that becomes an entry field of whether or not the product definition of the contract type is to be estimated, and the product definition of the contract type A product definition number and a pointer to the process definition check sheet main body 200b defined in association with the product definition of the contract type will be described.

  In the process definition check sheet main body 200b pointed to from the process definition check sheet header part 200a, as shown in FIG. 11, the flow of the business function of the product definition of the point source (the flow of the business function handled by the standard software package) And what the business functions (the business classifications and business functions shown in the figure) are, and the assignment to those business functions Software for the subordinate business functions provided in the standard software package that is provided in association with the index number defined to identify the subordinate business function belonging to each business function. Customer who will fill in the field as to whether the part needs to be changed It describes a's for the check mark entry column (beta shown in the figure).

  When a process definition check sheet 200 is distributed, a company engaged in a leasing business requesting an estimate of software development man-hours is entered in the quotation availability check mark entry field provided in association with the product definition to be estimated. While filling in a check mark and looking at the process definition check sheet main body 200b for explaining the flow of the product definition work to be estimated, the customization function provided in association with the work function that needs to be changed among those work functions By entering a check mark in the check mark entry field, information on what kind of software the company needs is written and notified to the software development company of the distribution source.

  Next, the modeling modification step file 20 will be described.

  The modeling remodeling step file 20 manages, for each business function executed in the product definition, information on which pattern function and index number the business function is to be executed, and Manages information about the scale of software modification required when changing business functions.

  FIG. 12 shows an example of the data structure of the modeling remodeling step file 20.

  As shown in this figure, the modeling remodeling step file 20 manages the pattern number and index number defined in the process definition check sheet 200 in association with the business number for each business function executed in the product definition. As a result, information about which pattern number and index number the business function is to be executed is managed, and the software (program) is associated with the pattern number and index number. By managing the number of steps of the modification scale, information on the scale of the software modification necessary for changing the business function is managed.

  For example, for a business function with a business number “27”, “contract management”-“application management”-“request application registration / modification”, a business whose pattern number is “P0027S01” and index number is “01”, etc. Necessary to change the business function when it is executed as a business function with the pattern number “P0027S01” and the index number “01”. It is managed that the modification scale of the software is 1500 steps.

  Next, the modification work man-hour estimation file 21 will be described.

  The remodeling work man-hour estimation file 21 is prepared as a work area of the remodeling work man-hour estimating unit 25, and is used for recording data obtained during the remodeling man-hour estimating unit 25 in the course of processing. Basically, it has the same data structure as the modification work man-hour estimation file 11 shown in FIG.

  FIG. 13 illustrates an example of a processing flow executed by the process definition analysis unit 23, and FIGS. 14 and 15 illustrate an example of a processing flow executed by the remodeling work man-hour estimation unit 25.

  Next, processing executed by the software development man-hour estimating device 1 of the present invention configured as shown in FIG. 9 according to these processing flows will be described in detail. First, processing executed by the process definition analysis unit 23 will be described.

  When the process definition check sheet 200 is collected from a company that operates a leasing business, the process definition analysis unit 23 first inputs the process definition check sheet 200 in step S40 as shown in the processing flow of FIG. . Note that the process of step S40 is not actually executed by the process definition analyzing unit 23 but executed by the input unit 22.

  Subsequently, in step S41, it is determined whether all the product definition numbers described in the process definition check sheet 200 (process definition check sheet header part 200a) have been selected, and all the product definition numbers are selected. When it is determined that there is no item, the process proceeds to step S42, and one unselected product definition number is selected in the order from the first product definition number.

  Subsequently, in step S43, the selected product is determined by determining whether or not a check mark is entered in the quotation availability check mark entry field (entry field in the α portion in FIG. 10) indicated by the selected product definition number. It is determined whether or not the product definition of the definition number is a target for estimation.

  When it is determined that the product definition of the selected product definition number is not an object of estimation according to this determination process, the process returns to step S41. On the other hand, when it is determined that the product definition is an object of estimation, the process returns to step S44. Then, the selected product definition number is recorded in the process definition analysis result storage unit 24.

  Subsequently, in step S45, the initial value 1 is set to the variable i, and in the subsequent step S46, the i-th business function (including the index number) described in the process definition check sheet body 200b pointed to by the selected product definition number. It is checked whether or not a check mark is entered in the check mark entry column for customization (i.e., the i-th business function counted).

  Subsequently, in step S47, it is determined whether or not it is detected that a check mark has been entered in accordance with this check process, and when it is detected that a check mark has been entered, the process proceeds to step S48, where i When the pattern number and the index number assigned to the second business function are recorded in the process definition analysis result storage unit 24 in association with the selected product definition number, on the other hand, when it is detected that a check mark is not entered, The process of step S48 is omitted.

  Subsequently, in step S49, the value of i is incremented by one. In the subsequent step S50, it is determined whether or not the value of i exceeds the maximum value imax of the business function identification number, and exceeds the maximum value imax. If it is determined that the maximum value imax has been exceeded, the process returns to step S41.

  In this way, when the processing of step S41 to step S50 is repeated, all the product definition numbers described in the process definition check sheet 200 (process definition check sheet header part 200a) are selected in step S41. When determining, the process is terminated.

  In this way, when the process definition check sheet 200 is collected from the leasing company, the process definition analysis unit 23 determines which product definition is to be estimated based on the entry in the process definition check sheet 200. That is, it is extracted which business function executed in the product definition needs to be changed, and the extracted information is processed to be recorded in the process definition analysis result storage unit 24. It is.

  Next, processing executed by the remodeling work man-hour estimation unit 25 will be described.

  When the process definition analysis unit 23 is started when the process definition analysis unit 23 finishes the process, the remodeling work man-hour estimation unit 25 first of all, as shown in the process flow of FIG. The unselected product definition number is selected in the order from the first product definition number recorded in step S61, and in step S61, the pattern number and the index number are recorded in association with the selected product definition number. Check whether or not.

  Subsequently, in step S62, it is determined whether or not it is detected that the pattern number and the index number are recorded according to this check process, and when it is detected that the pattern number and the index number are not recorded, Proceeding to S63, information indicating that it is not necessary to modify the software that realizes the product definition of the selected product definition number is recorded in the estimation result storage unit 26, and the process returns to step S60.

  On the other hand, when it is detected that the pattern number and the index number are recorded in association with the selected product definition number according to the determination process in step S62, the process proceeds to step S64, and the remodeling man-hour estimation file 21 is copied. Then, the modification work man-hour estimation file 21 for the product definition of the selected product definition number is created, and the initial value 0 is written in the modification scale recording area of the file.

  Subsequently, in step S65, one unselected pattern number and index number are selected according to the order from the first pattern number and index number recorded in association with the selected product definition number. Subsequently, in step S66, the number of steps of the modification scale is specified by referring to the modeling modification step file 20 using the selected pattern number and index number as a key, and the number of steps of the specified modification scale is determined as the number of modification work steps. Cumulatively add to the remodeling scale recording area of the estimate file 21.

  For example, if a pattern number “P0027S01” and an index number “01” (shown in FIG. 11) are recorded in association with the selected product definition number, “P0027S01” and “01” are used as keys. By referring to the modeling modification step file 20 having the data structure shown in FIG. 12, the modification scale of 1500 steps recorded in the corresponding place of the work number “27” is specified, and the modification scale of the modeling modification step file 20 is determined. If the initial value 0 is recorded in the recording area, the modification scale recording area of the work number “27” of the modification work man-hour estimation file 21 as the cumulative addition value as shown in FIG. The processing is performed so as to record 1500 steps.

  Subsequently, in step S67, it is determined whether all pattern numbers and index numbers recorded in association with the selected product definition number have been selected, and not all pattern numbers and index numbers have been selected. When it is determined that this is the case, the process returns to the process of step S65. On the other hand, when it is determined that all the pattern numbers and index numbers have been selected, the process proceeds to step S68, where all the process definition analysis result storage unit 24 records It is determined whether or not the product definition number is selected.

  When it is determined that all the product definition numbers recorded in the process definition analysis result storage unit 24 are not selected according to this determination process, the process returns to step S60, while the process definition analysis result storage unit 24 When it is determined that all the recorded product definition numbers have been selected, the process proceeds to step S69, and the software required to implement the product definition for which the remodeling work man-hour estimation file 21 is created is estimated. The estimation result is output and the process ends.

  Next, details of the processing executed in step S69 will be described according to the processing flow shown in FIG.

  When the remodeling work man-hour estimation unit 25 enters the process of step S69, first, as shown in the process flow of FIG. 15, first, in step S690, the remodeling work man-hour estimation file 21 (to the product definition number) is created. One remodeling man-hour estimation file 21 that has not been selected is selected from those created based on the above.

  Subsequently, in step S691, the initial value 1 is set to the variable j, and in step S692, the number of steps recorded in the recording area of the modification scale indicated by the work number j of the selected modification work man-hour estimation file 21 is set. In the subsequent step S693, it is determined whether or not the read modification scale step number indicates a non-zero value.

When it is determined that the read modification scale step number indicates a non-zero value according to this determination process, the process proceeds to step S694, and the parent scale record indicated by the job number j of the selected modification work man-hour estimation file 21 is recorded. Read the number of steps of the maternal scale recorded in the area,
Number of new conversion scale steps = ((number of remodeling scale steps / number of parent scale steps) + 1)
× (number of scale steps)
Calculate the number of steps of the new conversion scale according to the formula:
Remodeling man-hour = New conversion scale steps / 1000
However, the modification man-hours are calculated according to the calculation formula of 1000: 1 man-month steps, and the calculated values are recorded in the corresponding recording area of the selected remodeling man-hour estimation file 11.

In the example shown in FIG. 16, according to 1500 steps recorded in the remodeling scale recording area of the work number “27” of the remodeling work man-hour estimation file 21,
New conversion scale steps = ((1500/76500) +1) * 1500 = 1529
And based on that,
Remodeling man-hour = 1529/1000 ≒ 1.53
And the calculated values are recorded in the corresponding recording area of the selected modification man-hour estimation file 21.

  On the other hand, when it is determined that the read modification scale step number indicates 0 according to the determination process of step S693, the process of step S694 is omitted.

  Subsequently, in step S695, the value of j is incremented by one. In the subsequent step S696, it is determined whether or not the value of j exceeds the maximum value jmax of the business number, and does not exceed the maximum value jmax. Is determined, the process returns to step S692.

  On the other hand, if it is determined in step S696 that the value of j has exceeded the maximum job number jmax, the process proceeds to step S697 and is recorded in the remodeling man-hour recording area of the selected remodeling man-hour estimation file 21. The total number of remodeling man-hours is calculated, and the calculated value is recorded in the estimation result storage unit 26 in a form corresponding to the product definition number that is the creation source of the selected remodeling man-hour estimation file 21.

  Subsequently, in step S698, when it is determined whether all the remodeling work man-hour estimation files 21 created in step S64 are selected, and when it is determined that all the remodeling man-hour estimation files 21 are not selected, Returning to the process of step S690, when it is determined that all the modification work man-hour estimation files 21 have been selected, the process proceeds to step S699, the estimation result recorded in the estimation result storage unit 26 is output, and the process ends.

  That is, a list of paired data of the product definition number of the product definition to be estimated and the total remodeling man-hours for the software that realizes the product definition recorded in the estimation result storage unit 26 is output and processed. It ends.

  Note that the processing of step S699 is not actually executed by the remodeling work man-hour estimation unit 25 but is executed by the estimation result output unit 27.

  In this way, the software development man-hour estimating apparatus 1 of the present invention configured as shown in FIG. 9 distributes the process definition check sheet 200 to the company that operates the leasing business, and fills in the check mark. Just ask them to estimate the number of software development man-hours used to build the system required by the company. It should be noted that the process definition check sheet 200 may be filled in by having a software development company make a meeting with a company engaged in the leasing business.

  FIG. 17 illustrates another embodiment of the software development man-hour estimation device 1 of the present invention.

  When running a leasing business, the form creation process is one of the most important tasks. In view of this, the software development man-hour estimation apparatus 1 of the present invention shown in FIG. 17 employs a configuration that estimates the software development man-hours for executing the form creation processing based on the concept of the present invention.

  The software development man-hour estimation apparatus 1 of the present invention shown in FIG. 17 inputs a form definition check sheet 300 for estimating the software development man-hours used for realizing the form creation processing necessary for running the leasing business. Modeling remodeling step file 30, remodeling man-hour estimation file 31, input unit 32, form definition analysis unit 33, form definition analysis result storage unit 34, remodeling man-hour estimation unit 35, and estimation result storage unit 36 and an estimation result output unit 37.

  FIG. 18 illustrates an example of the data structure of the form definition check sheet 300.

  The form definition check sheet 300 shown in this figure is an estimate that becomes an entry field as to whether or not a form with the form name is to be estimated in association with a form name that may be created by a leasing company. Check mark entry field (α shown in the figure), pattern number of the form, explanation of what form the form is, information on which business function the form is created with, A list of the creation conditions for the form (index number assigned) and the software part for the form creation conditions provided in the standard software package that is provided in association with these form creation conditions A customization check mark entry field (β shown in the figure), which is an entry field as to whether or not it is necessary to change, is described.

  For example, in the standard software package that realizes the creation of a report called “Profit Statement”, “Y” is set for the report creation conditions such as the internal report form with index number “02” and the occasional creation with index number “06”. Describes that it has been realized by recording, and describes that the conditions for creating business forms such as business forms with the index number “01” are not realized by recording “blank” Then, blank check mark entry fields for customization are written in association with these form creation conditions.

  When a company that operates a leasing business that requests software development man-hours is distributed, when such a form definition check sheet 300 is distributed, a check is made in the quotation availability check mark entry field provided in association with the form to be estimated. By entering the mark and entering a check mark in the customizing check mark entry field provided in association with the form creation condition that needs to be changed among the form creation conditions realized in the form to be estimated, Information on what form the company needs is written and notified to the software development company of the distribution source.

  As for the form creation condition in which “blank” is recorded in the form definition check sheet 300, only one form creation condition is included in a group of form creation conditions belonging to a certain form creation condition (for example, output condition). Means that “Y” is recorded and “blank” is recorded because the other form creation conditions are not realized. Therefore, “Y” is recorded. If a check mark is entered in the check mark entry column for customizing the form creation conditions, it means that it is necessary to realize other form creation conditions under the same group.

  Next, the modeling modification step file 30 will be described.

  FIG. 19 shows an example of the data structure of the modeling remodeling step file 30.

  As shown in this figure, the modeling remodeling step file 30 manages the pattern number of the form and the index number of the creation condition of the form in association with the business number for each business function executed in the product definition. In the business function, information on which pattern number forms are created under what creation conditions is managed, and the software (program) is associated with the pattern number and index number. By managing the number of steps of the remodeling scale, information on the size of the software remodeling scale necessary for changing the form creation conditions is managed.

  For example, in the business function of “Estimate management”-“Estimate management”-“Lease / installment estimate profit contents registration / modification” with the business number “22”, the form with the pattern number “O0001A10” has the index number “ Since it manages that it will be created under a form creation condition such as “28”, it also manages that the scale of software modification required to change the creation of the form is 200 steps. is there.

  Next, the modification work man-hour estimation file 31 will be described.

  The remodeling work man-hour estimation file 31 is prepared as a work area of the remodeling work man-hour estimating unit 35, and is used for recording data obtained while the remodeling man-hour estimating unit 35 proceeds with processing. Basically, it has the same data structure as the modification work man-hour estimation file 11 shown in FIG.

  FIG. 20 illustrates an example of a processing flow executed by the form definition analysis unit 33, and FIGS. 21 and 22 illustrate an example of a processing flow executed by the remodeling work man-hour estimation unit 35.

  Next, according to these processing flows, processing executed by the software development man-hour estimating device 1 of the present invention configured as shown in FIG. 17 will be described in detail. First, the process executed by the form definition analysis unit 33 will be described.

  When the form definition check sheet 300 is collected from the leasing company, the form definition analysis unit 33 first inputs the form definition check sheet 300 in step S70 as shown in the processing flow of FIG. . Note that the processing of step S70 is not actually executed by the form definition analysis unit 33 but by the input unit 32.

  Subsequently, in step S71, it is determined whether all the form pattern numbers described in the form definition check sheet 300 are selected, and when it is determined that all the form pattern numbers are not selected, step S72 is performed. Then, one unselected form pattern number is selected in the order from the first form pattern number.

  Subsequently, in step S73, the selected form is determined by determining whether or not a check mark is entered in the quotation availability check mark entry field (the entry field of the α portion in FIG. 18) indicated by the selected form pattern number. It is determined whether or not the pattern number form is an estimation target.

  When it is determined that the form with the selected form pattern number is not subject to estimation according to this determination processing, the process returns to step S71, whereas when it is determined that it is subject to estimation, the process proceeds to step S74. Then, the selected form pattern number is recorded in the form definition analysis result storage unit 34.

  Subsequently, in step S75, the initial value 1 is set in the variable i, and in the subsequent step S76, the check mark entry field for customization indicated by the index number i of the form of the selected form pattern number (filling of the β portion in FIG. 18) is performed. Check whether a check mark is entered in the column.

  Subsequently, in step S77, it is determined whether or not it has been detected that a check mark has been entered in accordance with this check process, and when it is detected that a check mark has been entered, the process proceeds to step S78, where The number i is recorded in the form definition analysis result storage unit 34 in association with the selected form pattern number. On the other hand, when it is detected that a check mark is not entered, the process of step S78 is omitted.

  Subsequently, in step S79, the value of i is incremented by one, and in the subsequent step S80, it is determined whether or not the value of i exceeds the maximum value imax of the index number, and does not exceed the maximum value imax. Is determined, the process returns to the process of step S76. On the other hand, when it is determined that the maximum value imax has been exceeded, the process returns to step S71.

  As described above, when it is determined that all the form pattern numbers described in the form definition check sheet 300 are selected in step S71 when the processes in steps S71 to S80 are repeated, the process ends. .

  In this way, when the form definition check sheet 300 is collected from the company that operates the leasing business, the form definition analyzing unit 33 determines which form is to be estimated based on the entry in the form definition check sheet 300. And which one of the creation conditions of the form needs to be changed is extracted, and the extracted information is processed to be recorded in the form definition analysis result storage unit 34.

  Next, processing executed by the remodeling work man-hour estimation unit 35 will be described.

  When the form definition analysis unit 33 is started when the form definition analysis unit 33 completes the process, the remodeling work man-hour estimation unit 35 is first of all at step S90, as shown in the process flow of FIG. Whether or not an unselected form pattern number is selected according to the order from the first form pattern number recorded in step S91, and whether or not an index number is recorded in association with the selected form pattern number in the subsequent step S91. Check out.

  Subsequently, in step S92, it is determined whether or not it is detected that the index number is recorded in accordance with this check process. When it is detected that the index number is not recorded, the process proceeds to step S93, where the selection is made. The information indicating that it is not necessary to modify the software that realizes the creation of the form having the form pattern number is recorded in the estimation result storage unit 36, and the process returns to step S90.

  On the other hand, when it is detected that the index number is recorded in association with the selected form pattern number according to the determination process in step S92, the process proceeds to step S94, and the remodeling man-hour estimation file 31 is copied. A remodeling man-hour estimation file 31 for the form of the selected form pattern number is created, and an initial value 0 is written in the remodeling scale recording area of the file.

  Subsequently, in step S95, one unselected index number is selected in the order from the first index number recorded in association with the selected form pattern number. Subsequently, in step S96, the number of steps of the modification scale is specified by referring to the modeling modification step file 30 using the selected form pattern number and index number as a key, and the number of steps of the specified modification scale is modified. Cumulatively add to the record area of the modification scale in the man-hour estimation file 31.

  For example, if the selected form pattern number is “O0001A10” in the profit statement and the selected index number is “28” in “No title / document added / changed”, “O0001A10” and “28” are used as keys. By referring to the modeling modification step file 30 having the data structure shown in FIG. 19, the modification scale of 200 steps recorded in the recording area indicated by “O0001A10” and “28” of the work number “22” is specified. In the case where the initial value 0 is recorded in the remodeling scale recording area of the modeling remodeling step file 30, as shown in FIG. 23, as shown in FIG. The processing is performed so that 200 steps are recorded in the recording area of the modification scale number “22”.

  Subsequently, in step S97, when it is determined whether all index numbers recorded in association with the selected form pattern number are selected, and when it is determined that all index numbers are not selected, Returning to the process of step S95, on the other hand, when it is determined that all index numbers have been selected, the process proceeds to step S98, and whether or not all form pattern numbers recorded in the form definition analysis result storage unit 34 have been selected. Determine whether.

  When it is determined that all the form pattern numbers recorded in the form definition analysis result storage unit 34 are not selected according to this determination process, the process returns to step S90, while the form definition analysis result storage unit 34 When it is determined that all the recorded form pattern numbers have been selected, the process proceeds to step S99, and the software required to create the form in which the remodeling work man-hour estimation file 31 is created is estimated. The estimation result is output and the process ends.

  Next, details of the processing executed in step S99 will be described according to the processing flow shown in FIG.

  Upon entering the process of step S99, the remodeling work man-hour estimation unit 35 firstly, in step S990, the remodeling man-hour estimation file 31 (in the form pattern number) created in step S94, as shown in the processing flow of FIG. One of the unselected remodeling man-hour estimation files 31 is selected from those created based on the above.

  Subsequently, in step S991, an initial value 1 is set in the variable j, and in the subsequent step S992, the number of steps recorded in the recording area of the modification scale indicated by the job number j of the selected modification work man-hour estimation file 31 is set. In the subsequent step S993, it is determined whether or not the read modification scale step number indicates a non-zero value.

When it is determined that the read modification scale step number indicates a non-zero value according to this determination process, the process proceeds to step S994, and the parent scale record indicated by the work number j of the selected modification work man-hour estimation file 31 is recorded. Read the number of steps of the maternal scale recorded in the area,
Number of new conversion scale steps = ((number of remodeling scale steps / number of parent scale steps) + 1)
× (number of scale steps)
Calculate the number of steps of the new conversion scale according to the formula:
Remodeling man-hour = New conversion scale steps / 1000
However, the modification man-hours are calculated according to the calculation formula of 1000: 1 man-month steps, and the calculated values are recorded in the corresponding recording area of the selected remodeling man-hour estimation file 31.

If it demonstrates in the example shown in FIG. 23, according to 200 steps currently recorded on the recording area of the modification scale of the work number 22 which the modification work man-hour estimation file 31 has.
New conversion scale step number = ((200/3450) +1) × 200≈212
And based on that,
Remodeling man-hour = 212/1000 ≒ 0.21
And the calculated values are recorded in the corresponding recording area of the selected modification man-hour estimation file 31.

  On the other hand, when it is determined that the read modification scale step number indicates 0 according to the determination process of step S993, the process of step S994 is omitted.

  Subsequently, in step S995, the value of j is incremented by one, and in the subsequent step S996, it is determined whether or not the value of j exceeds the maximum value jmax of the business number, and does not exceed the maximum value jmax. Is determined, the process returns to step S992.

  On the other hand, when it is determined that the value of j exceeds the maximum value jmax of the work number according to the processing of step S996, the process proceeds to step S997 and is recorded in the remodeling man-hour recording area of the selected remodeling man-hour estimation file 31. The total number of remodeling man-hours is calculated, and the calculated value is recorded in the estimated result storage unit 36 in a form corresponding to the form pattern number from which the selected remodeling man-hour estimation file 31 is created.

  Subsequently, in step S998, when it is determined whether all the remodeling work man-hour estimation files 31 created in step S94 are selected, and when it is determined that all the remodeling man-hour estimation files 31 are not selected, Returning to the process of step S990, when it is determined that all the modification work man-hour estimation files 31 have been selected, the process proceeds to step S999, where the estimation result recorded in the estimation result storage unit 36 is output, and the process ends.

  That is, a list of paired data of the form pattern number of the form to be estimated, which is recorded in the estimation result storage unit 36, and the total modification man-hours for the software that realizes the form is output, and the process is terminated. It is.

  Note that the processing in step S999 is not actually executed by the remodeling work man-hour estimation unit 35, but is executed by the estimation result output unit 37.
