Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) This invention relates to a software development management system, and in particular to a software development management system for estimating the development period, development man-hours, and development cost necessary for software development. Regarding management systems.

(Prior Art) Generally, software resources are developed through work processes such as system design, program design, program creation, program unit testing, integration testing, and comprehensive testing. In order to complete the work process for software development in a short period of time and to develop high-performance software, it is necessary to formulate a sufficient development plan before the actual development work.

If this development plan is made correctly, even if the work does not proceed as planned, it will be possible to recover by correcting any part of the plan that has gone awry. If sufficient planning is not done, it will take time to clarify the cause-and-effect relationship of work delays, and it will not be possible to perform recovery at an appropriate time, resulting in increased confusion in the development project.

Such a development plan is usually created by referring to past development cases of similar software and making corrections that take into account the uniqueness of the software to be developed. The developed development plan is summarized as a software development estimate, and the estimate displays the development period, development man-hours, development cost, etc. required for software development.

However, when estimating the development time, development man-hours, and development costs for such software, it is necessary to make corrections that take into account the peculiarities of the software being developed, as mentioned above, so the estimates are not sufficient. It requires extensive knowledge and know-how from experience, and it is difficult to make an accurate estimate unless you are an experienced manager.

Further, even if the manager is a skilled manager, the estimation work is performed manually, and therefore estimation errors often occur due to calculation errors, omission of conditions, etc.

Furthermore, there are individual differences in the estimation results, and even for software development under the same conditions, the estimation results may differ depending on the person making the estimate.
The development period, development man-hours, and development costs may differ.

(Problems to be Solved by the Invention) Conventionally, software development estimates have been made manually, which has the drawback of requiring sufficient experience to make accurate estimates.

This invention was made in view of these points, and automatically changes the software development period and time simply by inputting conditions.
The purpose of the present invention is to provide a software development management system that can calculate development man-hours and development costs, and that can always make highly accurate estimates regardless of the experience of the estimator.

[Structure of the Invention] (Means and Effects for Solving the Problems) The software development management system according to the present invention is a system in which various conditions for calculating the development scale for software to be developed and specifying the development conditions are registered. A display means for displaying a configuration file and various conditions stored in this condition configuration file on a screen, and selecting and inputting conditions corresponding to the software to be developed from among the various conditions in the condition configuration file displayed on the screen. an input means, a standard process database in which information for calculating development time, development man-hours, and development costs from various conditions in the condition setting file are registered, and conditions input by the input means and the standard process; The present invention is characterized by comprising a calculation means for calculating a development period, a development man-hour, and a development cost corresponding to the software to be developed based on information in a database.

In this software development management system, various conditions of the condition setting file are displayed on the screen, so that the operator can input necessary conditions through input means in an interactive manner with the screen.

This prevents estimation errors due to omissions in inputting conditions.+I-
can do. Furthermore, when the conditions corresponding to the software to be developed are specified by the input means, the information in the standard process database is referenced to determine the development period for the software to be developed corresponding to the input conditions.
Development man-hours and development costs are automatically calculated. Therefore, it becomes possible to automatically calculate the software development period, development man-hours, and development cost just by inputting the conditions, and it becomes possible to always make highly accurate estimates regardless of the estimator's experience.

(Example) Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a software development management system according to an embodiment of the present invention. This software development management system is realized by a computer system such as a personal computer or a workstation, and includes a display device 11, a keyboard 12,
It includes an estimate calculation control section 13, a printer 4, a condition setting file 15, and a standard process database 16.

The display device 11 displays various operational guidance and calculation results for the operator on the screen. As the operation guidance, setting information on the software development scale and menu information on the development conditions stored in the condition setting file 15 are displayed.

Further, as a result of the arithmetic processing, information such as the software development period, man-hours, and costs automatically calculated by the estimate calculation control unit 13 is displayed as an estimate in a predetermined form.

The format of this development estimate is to provide information such as software development time, man-hours, and costs for each work item, that is, for each work such as system design, program design, program creation, program unit testing, integration testing, and comprehensive testing. Is there a format that shows each process, a format that shows only development costs such as personnel costs and miscellaneous expenses by year or month, or a format that shows the deployment of personnel for each work process by month? Regardless of the format of the estimate, information on software development time, man-hours, and costs are important parameters in creating each estimate.

The keyboard 12 displays the calculated value of the development scale (number of steps) and the number of function points of the software to be developed according to the operator's manual key operations, as well as the development of the software to be developed using the development condition menu displayed on the screen on the display 11. Enter conditions etc.

The estimate calculation control unit 13 uses the development scale and development conditions input from the keyboard 12 and the standard process database 16.
The development period, man-hours, and costs corresponding to the input conditions are automatically calculated based on the contents of the information. The result of this calculation is
It is displayed on the display 11 as an estimate in various formats, or printed out from the printer 14.

The condition setting file I5 stores contents to be displayed on the screen on the display 11 for guidance display to the operator. That is, the condition setting file 15 includes two tables SL and S2 for guidance display, and the contents of these tables SL and S2 are displayed on the screen.

Table S1 includes information that notifies the operator that the screen is for setting the development scale (development scale setting), information that instructs the operator to input the development scale (estimated number of development steps), and information that instructs the operator to input the number of function points ( number of functions) are registered.

The expected number of development steps is a value obtained by converting the development scale of the software to be developed into the number of execution steps of the software program, and is a value calculated by the administrator. The number of functions is calculated using the function point method (F
This is the number of points determined by each evaluation item in the scale estimation calculation method called P), such as the number of input screens, number of output screens, number of output forms, number of files, etc., and their types, and the number of points is large. As the development progresses, the scale of development also increases.

Registered in the table S2 are information (development conditions) that notifies the operator that the screen is for setting development conditions, and menu information for the development conditions.

The menu information includes an item to inquire about the presence of an online system, a section to inquire about the presence of a database, an item to inquire about the presence of a database, an item to inquire about the presence of technical novelty, and a special Items to inquire about whether a device is connected, items to inquire if there are any special requirements in terms of performance, items to inquire if there are any special requirements in terms of quality, items to inquire if there are any special requirements for troubleshooting, items to inquire about the development period. Section 1, which inquires about the experience of the person in charge of software development, is included.

The standard process database 16 has registered information for calculating the standard development period, standard development man-hours, and standard development cost from various conditions in the condition setting file. That is, the standard process database 16 includes a process step management table T1, a development step number calculation table T2, a step productivity variation coefficient table T3, and a skill table T.
4. It is equipped with a standard construction period calculation table T5, a personnel cost rank unit price table T6, and an overhead cost calculation table T7, and the contents of these management tables TI-T7 are stored in the estimate calculation control unit 1.
3 is used as a standard value or correction value for calculating development time, man-hours, and costs.

The process-specific step management table TI indicates the productivity standard value for each work process such as system design, program design, program creation, program unit test, integration test, and comprehensive test. is expressed as the estimated number of steps (number of steps/person-month) that can be created by one person working per month. The standard value of productivity for each work process varies depending on the size of the development scale.

The development step number calculation table T2 has 9 numbers corresponding to the number of function points input from the keyboard 12.
This shows the scale of 14 shots (number of steps).

The step productivity variation coefficient table T3 is based on the keyboard 1
This indicates a correction coefficient corresponding to the difficulty level determined by the development conditions such as the presence or absence of online availability input from 2, and this correction coefficient is used to calculate the number of development man-hours for each work process.

The skill table T4 shows the skills of the person in charge of the work required for each work process, and these skills correspond to the experience and skills of the person in charge of the work.

The standard construction period calculation table T5 is a table for calculating the standard construction period from the standard man-hours, and the standard construction period corresponding to the standard man-hour or the calculation formula for calculating the standard construction period is registered.

The personnel cost unit price table T8 is used to calculate the development cost, and, for example, the unit price of personnel costs is registered for each rank determined according to the skill of the person in charge of the work.

The miscellaneous expenses calculation table shows miscellaneous expenses such as machine usage costs and consumables costs relative to the total personnel costs.

The contents of these management tables Tl-T7 can be updated respectively.Next, the operation of the software development management system shown in FIG. 1 will be explained with reference to the flowchart shown in FIG.

First, the contents registered in the condition setting file 15 are displayed on the display 11 as operation guidance for the operator.
is displayed on the screen (step Al).

The operator determines the development scale (number of steps) of the software to be developed according to the inquiry information about the number of development steps and the number of functions displayed on the screen.
is input from the keyboard 12, and is read by the estimate calculation control section 13 (step A2). In inputting the development scale, the operator may, for example, input only the development scale calculated by himself or only the number of functions. Further, in step A2, each inquiry item of the development conditions registered in the condition setting file 15 is also displayed on the screen, and the corresponding development condition is designated by the operator. The specified development conditions are also read by the estimate calculation control unit 13.

Next, the estimate calculation control unit 13 refers to the corresponding management table in the standard process database 1B based on the read development scale calculation information and development condition designation information (step AI). Then, the estimate calculation control unit 13
From the contents of the management table, the development process and development period corresponding to the development scale and development conditions are calculated for each work process, and the personnel costs for each work process and miscellaneous expenses for each work process are also calculated as a standard case. Calculate (Step A
4).

After this, the estimate calculation control unit 13 calculates the calculated development process,
The development period and development costs (personnel costs + miscellaneous expenses) are displayed in a predetermined form on the display 11, and are printed out from the printer 14 if necessary.

As described above, in the software development management system of this embodiment, various conditions of the condition setting file 15 are displayed on the screen, so the operator can input the necessary conditions from the keyboard 12 in an interactive manner with the screen. can. Therefore, it is possible to prevent estimation errors due to omission of conditions.

Furthermore, when the conditions corresponding to the software to be developed are specified using the keyboard 12, the development period, development man-hours, and Costs are automatically calculated. Therefore, it is now possible to automatically calculate the software development period, development man-hours, and development cost just by entering the conditions.
It is possible to always make highly accurate estimates regardless of the experience of the estimator.

In addition, if the automatically calculated development period does not meet the delivery deadline, we will automatically calculate the estimate again using the shortened development period as the development condition and calculate the development man-hours corresponding to the specified delivery date. However, in this case, it is expected that the quality of the developed product will deteriorate.

For this reason, it is preferable to automatically calculate the quality of the development product along with the development man-hours, construction period, and development costs. Such quality calculation processing can be realized by further providing a management table for calculating quality in the standard process database 16.

[Effects of the invention] As described above, according to the present invention, software development time, development man-hours, and development costs can be automatically calculated simply by inputting conditions, and it is possible to calculate software development time, development man-hours, and development costs automatically regardless of the estimator's experience. It becomes possible to make highly accurate estimates.
