Description

  The present invention relates to a calculation method, a calculation device, and a computer program for realizing the calculation device for calculating a change degree of a job support system in response to a change request related to a job.

  For the construction of a business support system that supports various business, various specifications for designing the system, hardware and software modules that make up the system, test programs and test specifications for testing the system, etc. A huge number of parts and documents are required.

  When such a business support system is introduced or operated after the introduction, a change request related to the business occurs due to various factors. In such a case, after confirming what change is necessary for which part of the business support system, such as parts, documents, etc., verify that the system after the change works without problems. A CSV (Computerized System Validation) activity is carried out to maintain the verified state and record the verification result.

  As a technique for extracting the range of influence associated with a software function change, for example, an ID number is assigned to each software function, and when a function ID for specifying a function to be investigated is input, the function ID is searched. An influence range extraction system that displays an influence range list including chapter numbers in a document associated with a function ID is disclosed (see Patent Document 1).

  In addition, when relevance data indicating the presence or absence of direct relevance between two elements belonging to different classifications is stored, and designation of a specific element is accepted, the element is directly or via other elements By extracting elements that are indirectly related, you can immediately determine whether to change the design value for other elements that are affected by the change in the design value of a specific element. A design support apparatus that can significantly reduce the burden on the worker has been disclosed (see Patent Document 2).

In addition, in order to easily grasp the range of influence on the change request, the first matrix column indicating the relationship between the location of the software requirement specification and the location of the software design specification, the location of the software design specification Cross between specifications composed of a second matrix column indicating the relevance with the program specification description location and a third matrix column indicating the relevance between the program specification description location and the source program component. A reference table is disclosed (see Patent Document 3).

  However, in the system of Patent Document 1, the range of influence can be extracted is limited to the software function. In general, a change request for a business support system is not limited to a software function, but is related to a system such as hardware and documents, or a factor not directly related to the system, such as an infrastructure. There are many cases where a change request is made due to various factors, and there is a problem that the scope of influence cannot be grasped for such a change request.

  Further, in the apparatus of Patent Document 2, although other elements related to the design element are extracted to reduce the labor of the operator, since it is limited to the design element, it is similar to the example of Patent Document 1. In addition, when a change request is made due to various factors such as a business support system, there is a problem that it cannot be handled.

  Furthermore, in the example of Patent Document 3, although the relationship between the required software specifications and the design document or program code can be provided, the scope of influence on the entire system such as hardware and network infrastructure can be accurately grasped. There is a problem that you can not.

  The present invention has been made in view of such circumstances, and a calculation method and calculation capable of calculating a range of influence on a work support system, that is, a degree of change of the entire system, for a change request related to work. It is an object of the present invention to provide an apparatus and a computer program for realizing the calculation apparatus.

The features.

  The calculation device according to the second aspect of the present invention is based on a plurality of information databases in which information related to a business support system and an identifier for identifying the information are recorded in association with each other, and the business support system changes in response to a change request related to a business In the calculation device for calculating the degree, based on the association means for associating the information related between the information databases with each other by the identifier, the reception means for receiving the search condition for the change request, and the search condition received by the reception means A search means for searching each information database, a specifying means for specifying an identifier associated with the information in an information database in which information obtained by searching by the search means is recorded, and a specifying means specified by the specifying means Information associated with an identifier of another information database associated with the identifier and obtained by searching with the search means Based on the distribution, characterized by comprising a calculating means for calculating a change degree.

  According to a third aspect of the present invention, in the calculation device according to the second aspect, each of the information databases comprises user requirement information, functional requirement information, verification requirement information for verifying the user requirement information or functional requirement information, or a business support system. Any one of the component element information to be recorded is recorded, and the calculation means is configured to calculate a change degree based on the verification requirement information or the component element information.

  According to a fourth aspect of the present invention, there is provided a calculation device according to the second aspect, comprising: a setting unit configured to set an approval classification in association with the recorded information; and an approval classification associated with information related to the degree of change calculated by the calculation unit. Output means for outputting.

  A computer program according to a fifth aspect of the present invention provides a business support for a change request related to a business based on a plurality of information databases in which information related to the business support system and an identifier for identifying the information are associated with each other and recorded on the computer. In a computer program for calculating a degree of change of a system, an association means for associating information related to each other between the information databases with an identifier, a reception means for receiving a search condition for a change request, and a received search Search means for searching each information database based on conditions, specification means for specifying an identifier associated with the information in the information database in which information obtained by the search is recorded, and an identifier associated with the specified identifier Information associated with identifiers of other information databases Based on the retrieved information obtained, characterized in that to function as calculating means for calculating a change degree.

  In the first invention, the second invention, and the fifth invention, in each information database, information related to the business support system and an identifier for identifying the information are recorded in association with each other. The related information is associated with each other by an identifier. That is, related information among the information recorded across the information databases is associated with identifiers corresponding to the information. The business support system is a computer system for supporting various business operations, and includes various components and information such as hardware, software, and documents. When a search condition for a change request related to a business is received, each information database is searched according to the received search condition, and the information is identified in the information database in which information obtained from the search result is recorded. Specify the identifier to be used. In this case, the change request includes not only those directly related to the business but also those indirectly related and those considered to be related. Based on the identified identifier, an identifier of another information database associated with the identifier is identified. The degree of change is calculated based on the information corresponding to the identifier specified in the other information database and the information obtained from the previous search result.

  For example, by outputting (displaying) a list of information corresponding to identifiers specified in other information databases and information obtained from previous search results, it is possible to respond to a change request among information related to the business support system. The affected area can be clarified. Moreover, the change degree can be calculated quantitatively by including information in which the number of processes necessary for the change and the amount of work can be grasped in the information. As a result, it is possible to qualitatively and quantitatively understand the range of influence of the change request on the entire system. Also, when relevant information is extracted in the information database due to the search condition, relevant information can also be extracted from other information databases based on the information via the identifier, which has an impact on the change request. It is possible to grasp the receiving range without omission.

  In the third invention, each of the information databases is any of user requirement information, functional requirement information, verification requirement information for verifying the user requirement information or functional requirement information, or component information constituting the business support system. Is recorded. For example, the user requirement information database records user requirement information in association with a user requirement number that is an identifier. In addition, the functional requirement information database associates a user requirement number with a functional requirement number (identifier), and records functional requirement information (for example, a functional specification) in association with the functional requirement number. The verification requirement information database associates a user requirement number, a functional requirement number, and a verification requirement number (for example, a test script number) as an identifier, and also verifies the verification requirement information (for example, test contents) in association with the verification requirement number. Is recorded. Further, the component information database associates a component number (for example, a configuration item number) that is a user requirement number, a functional requirement number, and an identifier, and also configures component element information (for example, an item name, Or the type of hardware, software, or document).

  The calculation means calculates the degree of change based on the verification requirement information or the component element information. For example, by specifying the test script number and the test content based on the verification requirement information, the test amount for the change request can be grasped. Further, based on the component element information, it is possible to grasp the change range of software, hardware, documents, etc., which are configuration items constituting the business support system. As a result, it is possible to grasp not only a limited range of influence on software functions, design elements, program codes, etc., but also the degree of change with respect to configuration items constituting the entire system, as in the past. In addition, because the component information database is linked to other information databases via identifiers, it is possible to understand the effect of the change on the functional specification or the test even if there is a change in the system component. can do.

  In the fourth invention, an approval category (for example, an approval level) for the change request is set in association with the information recorded in the information database. When calculating the degree of change, an approval category related to information affected by the change request is output. Thereby, the approval level according to the change degree with respect to a change request | requirement can be determined, and it becomes possible to perform the actual change process after grasping | ascertaining the change degree rapidly.

  In the first invention, the second invention, and the fifth invention, it is possible to clarify the range affected by the change request among the information related to the business support system. In addition, by including information that can grasp the number of steps required for change and the amount of work in the information, the degree of change can be calculated quantitatively, and the range of influence on the entire system for change requests can be qualitatively and quantitatively determined. Can be grasped. Also, when relevant information is extracted in the information database due to the search condition, relevant information can also be extracted from other information databases based on the information via the identifier, which has an impact on the change request. It is possible to grasp the receiving range without omission.

  In the third aspect of the invention, as in the prior art, not only the limited scope of influence on software functions, design elements, or program codes, but also the degree of change to the configuration items that make up the entire system are understood. can do. In addition, because the component information database is linked to other information databases via identifiers, it is possible to understand the effect of the change on the functional specification or the test even if there is a change in the system component. can do.

  In the fourth invention, the approval level according to the degree of change with respect to the change request can be determined, and the actual change process after grasping the degree of change can be quickly performed.

That is an identifier for identifying each recorded information (record), and a requirement content (for example, a text-based record) associated with the user requirement number. ), A flag indicating the presence or absence of regulatory requirements such as laws or regulations, a requirement type indicating whether the recorded record is a business-related requirement (for example, business requirement, non-business requirement, etc.), and changing each record It consists of the approval level and so on.

  The approval level can be set according to the importance of information related to the business support system, and is, for example, SO (System Owner), VL (Validation Leader), or the like. The approval level may be an IT person in charge, a business person in charge, a project leader, or the like.

  The presence / absence of the regulatory requirement and the requirement type can be accepted as search conditions, and the search range of records can be set according to the search conditions.

  FIG. 3 is an explanatory diagram showing the structure of the FRS database 30. The FRS database 30 records functional requirement numbers (for example, FRS-001,...) In association with user requirement numbers. The functional requirement number is an identifier for identifying each recorded information (record). The FRS database 30 includes a requirement content (for example, a text-based record) associated with the functional requirement number, a requirement type (for example, application, infrastructure, network, etc.) of the recorded record, and an approval level when each record is changed. Etc.

  The requirement type can be accepted as a search condition, and a record search range can be set according to the search condition.

  FIG. 4 is an explanatory diagram showing the structure of the test item database 40. The test item database 40 records a test phase, a test script number, and a test step number in association with the user requirement number and the functional requirement number. The test phase, test script number, and test step number are identifiers for identifying each recorded information (record).

  The test phase includes, for example, DQ (Design Qualification: a stage for verifying whether it is designed according to user requirements and functional requirements), IQ (Installation Qualification: a stage for verifying whether it is installed according to requirements), OQ (Operational Qualification: requirements) It is composed of a stage for verifying operation according to function), PQ (Performance Qualification: stage for verifying whether it can be used for business), etc., and specifies a stage in the introduction or operation of the business support system.

  The test script number identifies a series of test processes for verifying a specific function, and indicates how much verification is required when making changes to the business support system. Can be estimated by number. The test step number identifies an individual test processing step in each test script.

  In addition, the test item database 40 records test contents (for example, text-based records) and test results (for example, text-based records) associated with test phases, test script numbers, and test step numbers. .

  FIG. 5 is an explanatory diagram showing the structure of the configuration management item database 50. The configuration management item database 50 records configuration item numbers (for example, ITEM-0001,...) In association with user requirement numbers and functional requirement numbers. The configuration item number is an identifier for identifying each recorded information (record).

  The configuration management item database 50 includes an item name (for example, a text-based record) associated with a configuration item number, a supplier name (for example, a text-based record), a type indicating the distinction between hardware, software, or a document, a document The version number of is recorded.

  The item name is, for example, a part name or a part model number, an application name, a document name, or the like. The supplier name is, for example, the name of a vendor that supplies parts, the name of a supplier company, and the like. A type indicating a distinction between hardware, software, and documents can be accepted as a search condition, and a record search range can be set according to the search condition.

  Each of the databases 20 to 50 described above is generated during the operation of introducing the business support system.

  The search processing unit 13 specifies an identifier for identifying the record in the database in which the extracted record is recorded as a result of the search. For example, if the extracted record is a user requirement as a result of the search, the user requirement number corresponding to the requirement content is specified. As a result of the search, if the extracted record is an item name, the constituent item number corresponding to the item name is specified.

  The search processing unit 13 specifies an identifier of another database associated with the identifier based on the identifier specified by the search result. For example, when a user requirement number in the URS database 20 is specified as a result of the search, an identifier (functional requirement number, test) associated with the user requirement number in the FRS database 30, the test item database 40, and the configuration management item database 50 Identify script number, configuration item number, etc. Further, for example, when a configuration item number in the configuration management item database 50 is specified as a result of the search, an identifier (user requirement number) associated with the configuration item number in the URS database 20, the FRS database 30, and the test item database 40 is identified. , Functional requirement number, test script number, etc.).

  The search processing unit 13 extracts a record corresponding to the identifier specified in another database and a record obtained from the previous search result, and outputs the extracted record to the change degree calculation unit 14.

  FIG. 6 is an explanatory diagram showing an example of record extraction. The example of FIG. 6 shows a case where there is a search hit in the URS database 20 as a result of searching each database according to the search condition. In this case, the search processing unit 13 first specifies the user requirement number URS-001 corresponding to the record extracted from the search result. Next, the search processing unit 13 specifies the function requirement numbers FRS-001 and FRS-002 associated with the user requirement number URS-001 in the FRS database 30.

  Further, the search processing unit 13 specifies the user requirement number URS-001 specified in the URS database 20 and the FRS database 30 and the script number associated with the functional requirement numbers FRS-001 and FRS-002 in the test item database 40. At the same time, the configuration item numbers ITEM-0001 and ITEM-0002 are specified in the configuration management item database 50.

  The search processing unit 13 extracts all records corresponding to the specified user requirement number URS-001, functional requirement number FRS-001, FRS-002, test script number, configuration item number ITEM-0001, and ITEM-0002.

  FIG. 7 is an explanatory diagram showing an example of record extraction. The example of FIG. 7 shows a case where there is a search hit in the configuration management item database 50 as a result of searching each database according to the search condition. In this case, the search processing unit 13 first identifies the configuration item number ITEM-0002 corresponding to the record extracted from the search result. The search processing unit 13 specifies the user requirement number URS-001 and the functional requirement number FRS-002 associated with the configuration item number ITEM-0002.

  The search processing unit 13 stores the user requirement number URS-001 specified in the configuration management item database 50, the user requirement number URS-001 associated with the functional requirement number FRS-002, and the functional requirement number FRS-002 in the FRS database 30. At the same time, the user requirement number URS-001 is specified in the URS database 20.

  The search processing unit 13 specifies the test script number associated with the user requirement number URS-001 and the functional requirement number FRS-002 specified in the FRS database 30 in the test item database 40.

  Further, the search processing unit 13 identifies the function requirement numbers FRS-001 and FRS-001 associated with the user requirement number URS-001 in the FRS database 30, and is associated with the function requirement numbers FRS-001 and FRS-001. The test script number is specified in the test item database 40, and the configuration item number ITEM-0001 associated with the functional requirement numbers FRS-001 and FRS-001 is specified in the configuration management item database 50.

  The search processing unit 13 extracts all records corresponding to the specified user requirement number URS-001, functional requirement number FRS-001, FRS-002, test script number, configuration item number ITEM-0001, and ITEM-0002.

  In the above example, the case where there is one search hit in one database is shown, but the same applies when there are a plurality of search hits in one database or there are search hits in a plurality of databases. All related records can be extracted.

  The change degree calculation unit 14 refers to the record extracted by the search processing unit 13 and calculates, for example, the number of scripts to be changed based on the test script number. Moreover, the change degree calculation part 14 specifies the approval level matched with the extracted record.

  The output unit 16 has an interface function with a display device such as a liquid crystal display and a monitor, and outputs the number of scripts calculated by the change degree calculation unit 14, the approval level, and all the extracted records.

  The storage unit 15 stores search conditions. Further, the storage unit 15 stores the processing results processed by the search processing unit 13, the change degree calculation unit 14, and the like. In addition, when a change request is made, the storage unit 15 temporarily stores information that is scheduled to be changed among information recorded in the URS database 20, the FRS database 30, the test item database 40, and the configuration management item database 50, Hold until CSV is complete.

  Each process in the control unit 12, the search processing unit 13, and the change degree calculation unit 14 can be realized by a dedicated hardware circuit. However, the processing unit is configured by a CPU, a RAM, a ROM, and the like. It can also be realized by loading a predetermined computer program into the RAM and causing the CPU to execute the computer program.

  Next, the operation of the calculation apparatus 10 according to the present invention will be described. FIG. 8 is a flowchart showing the procedure of the change degree calculation process. Hereinafter, in the flowchart, the main subject of the operation will be described as the control unit 12, but each process is performed not by the control unit 12 alone but by the calculation device 10 as a whole.

  A change request to the business support system is first made based on a change request from a user. FIG. 9 is an explanatory diagram showing an example of a change request form input screen. As shown in FIG. 9, the user inputs a change request on a text basis on a predetermined input screen. The input change request is transmitted to a CSV person in charge, for example.

  The control unit 12 determines whether there is a search condition input (S11). If there is no search condition input (NO in S11), the control unit 12 continues the process of step S11 and waits until the search condition is input.

  FIG. 10 is an explanatory diagram showing an example of a search condition input screen. As for the search condition, for example, the person in charge of CSV can set an appropriate keyword, search range, and the like based on a user change request. As shown in FIG. 10, as a search condition, an arbitrary keyword can be input in the user request, function specification, and configuration item columns. The search range can be specified by selecting a requirement type for a user request, a type for a functional specification, and a type for a configuration item from a pull-down menu. It should be noted that the fields for entering keywords can be combined into one.

  If there is a search condition input (YES in S11), the control unit 12 searches each database (S12), and records that match the keyword based on the input search condition (more specifically, matches the matching keyword). (S13). In addition, when it does not correspond to a keyword, you may determine the presence or absence of the record similar to a keyword.

  If there is a matching record (YES in S13), the control unit 12 extracts the record (S14) and, based on the identifier corresponding to the extracted record, determines another identifier associated with the identifier. Is searched (S15). The control unit 12 extracts a record corresponding to the identifier specified in another database, that is, a related record (S16), and outputs a list of all the extracted records (S17).

  11 and 12 are explanatory diagrams illustrating an example of the search result screen. As shown in FIG. 11, a user requirement number and requirement content, a functional requirement number and requirement content, a test volume (number of test scripts), an approval level, and the like are displayed on the screen showing the planned change content. Moreover, as shown in FIG. 12, the configuration item number and the item name are displayed on the screen showing the scheduled change configuration item. The person in charge can grasp the degree of change of the system in response to the change request from the change schedule content or the change schedule configuration item displayed on the search result screen.

  In addition, the person in charge can select the content or item to be actually changed from the content displayed on the search result screen, or enter the search condition again and add the content or item to be changed. You can also Further, the screens shown in FIGS. 11 and 12 can be simultaneously displayed on one screen.

  The control unit 12 determines whether or not a search condition has been input (S18). If there is a search condition input (YES in S18), the control unit 12 continues the processing from step S12 and repeats the record extraction for the change request again. When there is no search condition input (NO in S18), the control unit 12 calculates the degree of change (S19), extracts the approval level (S20), and ends the process.

  13 and 14 are explanatory diagrams showing an example of a screen for inputting the requirement content after the change. As shown in FIG. 13, the scheduled change contents and the scheduled change configuration items are limited to those selected by the person in charge, and the contents and items that were not selected are deleted from the list. Further, the person in charge can grasp the contents of the change schedule and input the requirement contents after the change to correct the contents of the change schedule.

  For example, as shown in FIG. 13, in response to the requirement content that “there should be an input screen for clinical trial notification” as the content to be changed, the person in charge should have “an input screen for clinical trial notification and an input assist function” You can change the contents of the change schedule. In addition, as the scheduled change content, the person in charge says that “the memory must have at least 1 GB required by the application”. It is possible to change the scheduled change contents such as “being secured”. Note that the screens shown in FIGS. 13 and 14 can be simultaneously displayed on one screen.

  15 and 16 are explanatory diagrams showing examples of the change degree display screen. As shown in FIGS. 15 and 16, the scheduled change content is displayed as the qualitative change degree, and the scheduled change configuration item (number of items) and the change volume (number of scripts) are displayed as the quantitative change degree. In addition, the approval level regarding the scheduled change content is displayed. Note that the screens shown in FIGS. 15 and 16 can be simultaneously displayed on one screen.

  If there is no matching record in step S13 (NO in S13), for example, the control unit 12 displays that there is no record corresponding to the search condition and prompts the person in charge to input the search condition again. The control unit 12 determines whether there is a search condition input (S21), and if there is no search condition input (NO in S21), the process ends. When there is a search condition input (YES in S21), the control unit 12 continues the processing from step S12.

  As described above, in the present invention, the range that is affected by the change request is clarified in the information related to the system constructed or operated by hardware, software, documents, etc. such as the business support system. Can be. In addition, by including information that can grasp the number of steps required for change and the amount of work in the information, the degree of change can be calculated quantitatively, and the range of influence on the entire system for change requests can be qualitatively and quantitatively determined. Can be grasped. In addition, when related records are extracted in one database by the search condition, related records can be extracted from other databases based on the records via the identifier, so that the change request is affected. It is possible to grasp the receiving range without omission.

  Further, as in the prior art, it is possible not only to grasp a limited range of influence on software functions, design elements, program codes, etc., but also to grasp the degree of change with respect to configuration items constituting the entire system. In addition, because the configuration management item database is linked to other databases via identifiers, even if there is a change in the system configuration item, the effect on the functional specification or the test due to the change must be understood. Can do. Moreover, the approval level according to the change degree with respect to a change request can be determined, and the actual change process after grasping the change degree can be quickly performed.

  In the above-described embodiment, the URS database 20, the FRS database 30, the test item database 40, and the configuration management item database 50 have been described. However, the database is an example, and is not limited thereto. It is not limited to four. The four databases described above may be configured to be stored in physically different storage devices such as hard disks, or may be configured to store the databases separately in one storage device.

  In the above-described embodiment, the user requirement number, the function requirement number, and the like have been described. However, the identifier is an example and is not limited thereto.
