Description

  The present invention relates to a system for managing a project related to development when developing software or the like. In particular, it is a system for performing efficient management by paying attention to the traceability of specifications described in deliverables such as documents.

  Conventionally, processes and deliverables have been handled as management targets in project management such as software development. Here, change management of processes, deliverables, etc. occupies a large element as an act of management. Conventional change management has been performed by providing a table for associating related deliverables after creating the deliverables.

  For example, in the case where deliverables such as documents generated in the flow of development work are managed using a structure representation based on the deliverable composition, when a specification change occurs in a part of the deliverable, the impact range is improved. In other words, an influence range extraction system including an extraction unit has been proposed (see, for example, Patent Document 1).

  In the computer system that handles the product configuration table, the technique described in Patent Document 1 uses (1) a specification change input unit that inputs change specification contents, and (2) the change specification contents described above. (3) using the flow element extraction unit that extracts the influence element from the “information file” and the influence element obtained from the above, the influence on the configuration from the “product configuration file” and the “related configuration file” (4) Using the “deliverable state file” from the affected artifacts obtained above, the artifacts that are substantially affected by considering the progress over time And (5) an output unit for displaying the selected product, and only a substantial influence range at the time of changing the specification can be extracted.

  In addition, when a certain product needs to be modified, it is necessary to automatically search for the related product and use the optimal procedure for correcting the product, and automatically correct the product. There has also been proposed a software development product management method and apparatus that maintain consistency between products by making modifications to (see, for example, Patent Document 2).

  In the technology described in Patent Document 2, every time a product is created by a development tool, the modification dependency between the products related to the tool and the development product in the modification dependency are corrected from the unmodified state. In addition to registering information indicating the playback procedure, which is a procedure for setting the status, in the first table (corrected dependency table), information indicating the corrected product is displayed each time the product is corrected by the development tool. Record in the second table (amendment record table), and based on these amendment dependency table and amendment record table, find the newly required deliverables and follow the corresponding rehabilitation procedure. This is characterized by correcting the above.

Here, the corrected dependency relationship is a relationship when the deliverable B needs to be corrected when the deliverable A is corrected, and the deliverable A and the deliverable B are called to have a corrected dependency relationship. , A> B. In addition, A is referred to as a left side (left-side product) in this relationship, and B is referred to as a right side (right-side product). Next, the reproduction procedure has a modification dependency expressed as A> B, and when the product A is modified, the reproduction of the product B is to change the product B from the unmodified state to the modified state. The procedure for this purpose is called the reproduction procedure of the deliverable B.

However, the above technique has the following problems.
(1) Correspondence work occurs for each project.
-Creation of a related configuration in Patent Document 1-Creation of a correction dependency table and correction record table in Patent Document 2 (2) The correspondence material must be corrected each time a product is added or deleted.
-Correction of the related configuration in Patent Document 1-Correction of the correction dependency table and correction record table in Patent Document 2 (3) Management in units of specifications is not possible.
Both enable specification change management in units of documents (deliverables), but cannot be managed in units of specifications described in the documents.

  The present invention has been made to solve the above-described problems, and depends on traceability between specifications (hereinafter referred to as specification descriptions) described in the product based on the product data. Generate model data related to relationships and simplify the task of establishing traceability. And if there is a change in the specification description etc. of the deliverables, the affected area can be identified based on the model data, and it is possible to handle the notification process etc. The purpose is to obtain a project management system that supports the project.

  The project management system according to the present invention is a product configuration model storage means for storing a configuration of a product whose specifications are described based on a predefined configuration as product configuration data, and a plurality of products, Traceability model storage means for storing the traceability relationship of specifications described in deliverables as traceability model data in advance, tasks that represent deliverables as input / output parameters, dependency relationships between tasks, and tasks Project life cycle model storage means for storing data related to the person in charge as project life cycle model data, and when the specifications described in the deliverables are changed, the results of downstream processes that are affected by the change based on the traceability model data Specify the specifications related to Based on the product configuration data, identify the deliverables with the specified specifications. Furthermore, based on the project life cycle model data, the tasks using the identified deliverables as input parameters, the dependency between tasks, and the task An influence range specifying processing means for specifying a person in charge and a notification processing means for performing a notification process for the person in charge specified by the influence range specifying processing means.

  As described above, according to the present invention, the traceability model data relating to traceability is stored in advance in the traceability model storage means, so that the task of establishing traceability can be simplified. Further, by automatically converting, generating, storing and managing the traceability model data, it contributes to the improvement of quality control and can cope with IT control such as so-called SOX method. Then, when there is a change in the specification described in the deliverable, the impact range identification processing means performed the deliverable, task, dependency between tasks and task related to the change based on the traceability model data. The person in charge (creating the deliverable) is identified, settings related to the return process are made, and the communication processing means performs notification processing to the person in charge, so the settings related to the return process can be performed automatically. It is possible to automatically notify the person in charge who may change the specification described in the deliverable through the rework process. And, for example, if the specification is further changed by the specified person in charge, it is possible to identify the affected area from the upstream process to the downstream process in the project. Therefore, it is possible to prevent the quality from being deteriorated. Since the influence range can be automatically specified without fail, it can contribute to the reduction of man-hours related to the setting of the rework process.

Embodiment 1 FIG.
FIG. 1 is a block diagram showing an apparatus configuration centering on a project management system according to an embodiment of the present invention. In FIG. 1, the project management system 1 includes a management processing device 10, a storage device 20, and a communication device 30. The management processing device 10 is a device for processing and managing various data relating to a project. In particular, in the present embodiment, data in a file format related to deliverables and process plans (hereinafter referred to as deliverable data and process plan data) is processed, and data is generated by performing conversion based on three models described later. And stored in the storage means 20. Also, if there is a change in deliverable data, specify the range affected by the change (developer etc. (hereinafter referred to as person in charge) who may perform a rework process and modify the deliverable) Then, data related to the rework process is generated according to the setting related to the rework process, and the person in charge is notified. It is assumed that the management processing apparatus 10 according to the present embodiment includes a model conversion unit 10A, an influence range specifying processing unit 10B, and a notification processing unit 10C.

  The model conversion means 10A, for example, based on product data and process plan data included in a signal transmitted via the network 100 or the like, a product configuration model, a project life cycle (process plan) model, and traceability (to be described later) Traceability) Performs processing to convert and generate data (being an instance) based on the model. Then, the data related to the conversion is stored in each storage unit of the storage device 20.

  The influence range specifying processing means 10B determines and specifies the range of tasks, deliverables, etc. affected by the change based on the traceability model data when the change is made with respect to the deliverable data. This is means for specifying a person in charge for performing the setting process for the rework process.

  Based on the request from the terminal 200 transmitted via the network 100, the communication processing unit 10C searches for template data or the like according to the request from the document data storage unit 20E, for example, and communicates a signal including the data or the like. Transmit from the device 30. Then, based on a request from the terminal 200, a signal including traceability model data and the contents of the data is transmitted from the communication device 30. Further, the data of the e-mail address of the developer who created the product by performing the process related to the influence range specified by the influence range specifying processing means 10B is searched from the notification data storage means 20D. Then, a process for notifying by e-mail so as to confirm the change of the specification description is performed.

  Here, regarding the management processing apparatus 10, it can be configured only by a dedicated device (hardware), but generally, for example, an arithmetic control means (computer) centering on a CPU (Central Processing Unit) is used. Configure the hardware. Then, the processing procedure performed by each means of the management processing device 10 is programmed in advance and stored as software, firmware, etc., for example, in the storage device 20 or the like, and the arithmetic control means executes the program so that the processing of each means is performed. To do.

  The storage device 20 is a device for temporarily or long-term storing data necessary for the management processing device 10 to perform processing and various data relating to a project. In particular, in the present embodiment, the storage device 20 includes deliverable structure model storage means 20A, project life cycle model storage means 20B, traceability model storage means 20C, notification data storage means 20D, document data storage means 20E, and results. It is assumed that the product data storage means 20F is at least included. The product configuration model storage unit 20A, the project life cycle model storage unit 20B, and the traceability model storage unit 20C each store data of each model converted and generated by the model conversion unit 10A. In addition, the notification data storage unit 20D stores data for the communication processing unit 10C to send an e-mail to the developer, such as data on the developer's e-mail address such as a product related to the project. Further, the template data storage means 20E includes a process plan, a deliverable, a change request for requesting a change of the deliverable, a review report for approving the correction contents of the deliverable, and various types for monitoring the project status. Form (template) data of various documents for developers to create forms and the like is stored in a predetermined format (for example, data in a format that can be converted into XML format or XML format data). It also stores data such as guidelines and samples for developers to create deliverables. Although not particularly limited here, the storage device 20 may be configured by a plurality of physically different devices.

  The communication device 30 is a device that serves as an interface between the management processing device 10 and the network 100. A signal transmitted via the network 100 is converted into a signal in a format that can be processed by the management processing apparatus 10. Conversely, the signal from the management processing device 10 (particularly the communication processing means 10C) is converted into a signal that can be transmitted to the network 100. Unless otherwise specified, signal communication via the network 100 in the management processing device 10 is performed via the communication device 30. Here, although not particularly provided in the present embodiment, a display device (means) and an input device (means) are provided in the project management system 1, and the project management system 1 inputs product data, data related to instructions, and the like. The work performed on the terminal 200 may be directly performed.

  The network 100 is a communication network that can perform electrical communication regardless of wired or wireless. The terminal 200 is a computer similar to the management processing apparatus 10 used by a developer of deliverables and the like related to the project. Although not particularly illustrated, the terminal 200 includes a display unit, an input unit, and the like. For example, the terminal 200 receives a request for data processing or the like from the project management system 1 and a signal including various data stored in the project management system 1. This is a device for developers and the like to give instructions such as transmission requests. In addition, support such as creation, correction, and confirmation of deliverables by developers and process schedules by project managers will be provided. It is assumed that terminal 200 in the present embodiment can communicate signals including various data with management processing apparatus 10 via network 100.

  In the system of the present embodiment, for example, each model is converted and generated based on the process plan data and product data from the terminal 200 and stored as model data. Here, model data relating to traceability is converted and generated based on the specification description in the deliverable performed by the developer in the upstream process. For example, in the software development process, a task is performed from an upstream process to a downstream process, and a product is created. In this embodiment, when a deliverable in the downstream process is created, the traceability dependency with the specification description of the upstream process is not set, but tracking is performed in advance at the stage of creating the deliverable in the upstream process. Make settings so that you can. Thereby, the person in charge instantiates the specification description in the deliverable together with the traceability according to the traceability model, stores it as model data in the storage device 20 (traceability model storage means 20C), and establishes traceability. To simplify the process. In addition, by generating traceability model data in advance, it can also serve as a guideline so that the developer (downstream process) does not deviate from the defined specification system.

  Then, when the change request document for the change in the specification description etc. in the deliverable is registered, the influence range specifying processing means 10B includes the traceability model storage means 20C, the deliverable configuration model storage means 20A, and the project life cycle model storage. Search for means 20B, and based on the traceability model, determine and identify the range affected by the change in the specification description, and the person in charge who created the deliverable (performs the rework process) by performing the tasks related to that range Then, settings relating to the rework process are performed, and data relating to the rework process is generated. Further, the communication processing means 10C retrieves the data of the developer's mail address from the notification data storage means 20D, notifies the change by electronic mail, and the task, deliverable, etc. affected by the change based on the change. Keep track of everything.

  FIG. 2 is a diagram illustrating the relationship among the product configuration model, the project life cycle model, and the traceability model. Here, software development activities can be expressed by three relationships: product structure, process plan (project life cycle), and traceability (traceability). In the present embodiment, modeling is performed from three viewpoints (delivery structure management, project life cycle management, and traceability management), and various results are generated so that model data can be converted and generated based on each model. Description contents such as specification descriptions in the deliverables are determined (defined) for the objects.

  FIG. 3 is a diagram illustrating an example of a deliverable in the present embodiment. FIG. 3 shows an example of a part of a software requirement specification (template) created by a person in charge of software development. The deliverable is, for example, a document (document) describing the specification in text, a change request document, a review report, a project form, a UML model for confirming the validity of the specification described in text, based on the specification This refers to all specification descriptions created for system implementation in software development projects, such as test cases and test data for evaluating that the created source code and specifications are implemented in source code without excess or deficiency.

  The deliverable is an element constituting the deliverable of the project, and is an input / output parameter of a task (activity) constituting the process in the process management. In particular, in the present embodiment, the traceable specification description for establishing the abstract dependency is provided for traceability management. In other words, defining the deliverables (tracking dependency of the specifications described in the deliverables) is the most important for configuration management, project planning, execution, and quality control, and will be given priority over everything. .

  In the development process, deliverables are defined by sentences and forms such as guidelines and templates. For example, the deliverables are classified as a set of deliverables for each theme, and guidelines and templates are prepared for each deliverable. The input / output parameters of the tasks that make up the development process may be modeled in document units, but in order to manage traceability, it is necessary to model up to the specification description units that make up the document. .

  The deliverable is composed of documents having various types of specification descriptions regardless of the level of abstraction of specifications (stages such as requirements, design, and implementation). The definition of the product indicates the classification of the product and what kind of specification description each product is composed of. The product configuration model is a model of this in units of documents. A product template (form), a guideline for creation, a sample, and the like are stored in the document data storage unit 20E, and a person in charge such as a person in charge can store these in the management processing apparatus 10 via the terminal 200. It is possible to request data and create a product (data) by data processing or the like performed via the terminal 200.

  In the present embodiment, the conventional guideline on how to write the specifications in the concept is replaced with the meta model, and the template on how the specifications are written in accordance with the guidelines is replaced with the model. Become. Furthermore, by modeling the product structure, it can be linked with the project life cycle model and traceability model.

  Next, the process life cycle model will be described. The process life cycle model is a series of tasks (activities) constituting a software development activity along a time axis, and is represented as a process table such as a Gantt chart. Model the project from a life cycle perspective. Then, the process plan data based on the model is converted into the input of the workflow engine to realize the automation of the development process. In the process plan data described in detail based on the model, attributes such as a start date and an end date for each task are set.

  FIG. 4 is a diagram showing a specific example when the traceability model data is visually represented. A series of development phases such as requirement definition, basic design, detailed design, and implementation can be considered as a process in which the specification description of the upstream process is made concrete toward the downstream process. Traceability represents a dependency relationship between such specification descriptions.

  Conventionally, when creating a deliverable such as a specification document, a dependency that can be traced is generated between the added specification description and the higher-level specification description every time a specification description is added, and this dependency relationship is recorded, for example. The traceability was established. In other words, when the person in charge writes a new specification in the specification, the person in charge registers the specification description in which of the specifications in the upstream process this new specification description. I was doing. Specifically, data for managing traceability called a traceability matrix is sequentially maintained. However, the maintenance work of the traceability matrix is very complicated when the granularity of the specification description to be managed is made finer and the traceability management is finer.

  Therefore, if the traceable relationship between the specification specifications of the deliverables is modeled in advance as a traceability model for the modeled deliverable composition, the person in charge will create the deliverables at the upstream process stage in advance. According to the traceability model, the specification description can be instantiated along with traceability, so that the task of establishing traceability can be simplified. In addition, modeling the deliverable structure and defining (setting) an easily traceable structure with awareness of traceability at the stage of creating the deliverable will further simplify the task of establishing traceability during development. You can also The influence range specifying processing unit 10B performs, for example, an influence range specifying process when there is a change in the product data, based on the traceability model data.

  FIG. 5 is a diagram illustrating a flowchart of a system related to a change of specifications centered on the management processing apparatus 10. Based on FIG. 5, for example, the operation of the system when a signal including product data related to a change request document is transmitted for the description content of a software requirement specification (hereinafter referred to as a specification) will be described.

  FIG. 6 is a diagram illustrating an example of a change request form. In accordance with the change request determined by the change request management, for example, a manager or the like creates a change request document (delivery product) for a specification description by a person in charge in the most upstream process. At this time, the terminal 200 performs a support process for creating a change request form by the administrator. A signal including the change request form as product data is transmitted to the management processing apparatus 10 via the network 100 (ST1). The deliverable data of the change request form is stored (registered) in the deliverable data storage means 20F.

  The influence range specification processing means 10B is affected by changing the specification description by the person in charge in the most upstream process based on the traceability model data stored in the traceability model storage means 20C. Determine and specify the specification description of the deliverable (SS1). Here, it is assumed that the influence range specification processing unit 10B specifies all the affected specification descriptions at once. Although the influence range may be specified for each stage of the process, the size of the affected range can be grasped by specifying it at a time.

  Further, based on the specification description determined to be affected and the product configuration model data stored in the product configuration model storage means 20A, the specification (development) in which the specification description is described is further determined. (SS2).

  Then, based on the determined document and the project life cycle model data stored in the project life cycle model storage unit 20B, a task using the document as an input parameter is further determined and specified (SS3). In addition, the dependency relationship between the tasks and the person in charge who will perform the determined task are determined and identified (SS4).

  The identified task or the like becomes a return, and is attached to a return process that occurs as a new process. The influence range specification processing unit 10B performs setting related to the rework process based on the specified specification description, specification, task, person in charge, etc., and data related to the rework process (delivered data related to the rework process, (Association data such as traceability model data and project life cycle model data) is generated (SS5). Here, although the flow is different from the flow of this flowchart, the communication processing means 10C transmits an e-mail to the project manager who manages the process of the project when the return process is set, and the project manager Confirms the return process and sets the start date and end date of the task related to the process.

  The communication processing unit 10C searches the notification data storage unit 20D for the e-mail address of the person in charge specified by the affected range specification processing unit 10B. Then, an e-mail is transmitted based on the e-mail address, and notification of confirmation of contents instructed to change the specification (return process occurs) is notified to, for example, a person in charge in the most upstream process ( SS6). In the present embodiment, this change instruction can be made in units of specifications. The e-mail includes data for determining whether to change the specification description, such as traceability model data, and the person in charge who sent the e-mail makes changes based on the contents of the data. You can decide whether to do it.

  Based on the instruction from the person in charge, the terminal 200 displays the contents of the e-mail on the display means (not shown), and further requests transmission (retrieval) of the specification related to the change instruction (ST2). The communication processing means 10C transmits a signal including product data based on the request (SS7). The person in charge determines whether to change the specification description based on the displayed contents, and gives an instruction to the terminal 200. The terminal 200 determines whether there is a change based on the instruction (ST3). If there is a change, the person in charge performs support processing for changing the specification description of the specification (ST4).

  Further, the change history column of the specification is changed (ST5). On the other hand, if the person in charge determines not to change the specification description (the terminal 200 determines that there is no change), only the change history column of the specification is changed. Specifically, for example, character data such as “no change” or “N” is input in the change history column. The terminal 200 performs support processing for that purpose. A signal including the product data is transmitted to the management processing apparatus 10 via the network 100 using the specifications after the above changes as product data. The product data of the specifications is stored in the product data storage means 20F. Here, the management processing apparatus 10 that has received the signal does not perform conversion generation of model data based on the product data of the specification at this stage.

  The person in charge creates a review report (product). A review report is a report that has been reconfirmed with respect to a product whose specification description has been changed. For example, a check list regarding contents to be confirmed is provided. Terminal 200 performs a review report creation support process (ST6). Using the review report as product data, a signal including the product data is transmitted to the management processing apparatus 10 via the network 100. The product data related to the review report is stored in the product data storage means 20F. Then, using the registration of the product data related to the review report as a trigger, the model conversion unit 10A generates model data based on the product data related to the specification and stores it in each storage unit (SS8).

  Then, the communication processing unit 10C determines whether it is necessary to notify the person in charge affected by the specification description related to the change by e-mail (SS9). For example, when the specification description is changed, it is determined that notification by electronic mail is performed. Further, when “no change”, “N”, or the like is entered in the change history column and no change has been made to the specification description, it is determined that it is not necessary to notify by e-mail. In SS4, all the persons in charge who are affected are specified. Here, for example, it is determined whether or not to notify the person in charge who performs the task of the one-stage downstream process. Thereby, the notification by the electronic mail performed by the communication processing unit 10C can be sequentially performed from the person in charge of the specification with a high abstraction level (in the upstream process), for example. For example, it is possible to notify the person in charge who created each specification in the order of document, model, and source code.

  If the management processing apparatus 10 determines that it is necessary to notify by e-mail, the management processing apparatus 10 performs the above-described SS6 process again and notifies a necessary person in charge. The above processing is performed until it is determined that the person in charge who has notified by e-mail has changed only the change history column without changing the specification description, and no person in charge has been affected.

  As described above, according to the system of the first embodiment, the traceability model data is set in advance in the management processing apparatus 10 by setting the traceability in the specification (product) and generating the conversion by the model conversion unit 10A. Since it is stored in the traceability model storage means 20C, the work of establishing traceability can be simplified. When a change request for specification description based on the change request is registered, the influence range specifying processing unit 10B searches the traceability model data storage unit 20C and the like, and the specification, task, and task related to the change. Since the person in charge who executed the task (created the deliverable) was specified and the communication processing means 10C notified by e-mail, the specification description could be changed by the rework process. The person in charge can be notified by e-mail automatically by the system. In addition, the determination of whether to change the specification description in the deliverable related to the task by the notification is performed by the person in charge who has received the notification. Since the influence range can be specified without exception from the upstream process to the downstream process, it is possible to save labor in the influence range analysis and prevent quality deterioration due to omission of reflection of requirements. By performing the specification of the influence range without fail, the reworking process can be performed reliably and efficiently. Furthermore, in this embodiment, when a change request document is registered, a process for specifying an impact range is performed, and when a review creation document is registered, a model conversion of a specification (product) related to the specification description conversion is performed. Since the processing is performed, the product data related to each document is memorized so that the identification of the requester, the history, the changed specification description, the changed content, the change confirmation status, etc. can be easily grasped. be able to.

Embodiment 2. FIG.
FIG. 7 is a diagram illustrating a flowchart of a system related to change of a product centering on the management processing apparatus 10 according to the second embodiment. In the first embodiment described above, the change request form is transmitted as the product data, and the influence range is specified and notified by using the registration as a trigger. In the present embodiment, the specification, etc. with the changed specification description is transmitted as product data and registered, and the influence range is specified and notified, etc., as a trigger. The configuration of the system is not particularly changed and will be described with reference to FIG.

  For example, in accordance with the change request, the person in charge who is positioned in the most upstream process among the processes related to the product change performs, for example, data processing on the terminal 200 to create a specification (product) related to the change. The terminal 200 performs support processing for creating a specification related to the change by the person in charge. A signal including the management processing apparatus 10 is transmitted via the network 100 using the specification after the specification description is changed as product data (ST11). The product data of the specifications is stored in the product data storage means 20F.

  The model conversion unit 10A of the management processing device 10 generates product configuration model data and traceability model data based on the product data of the changed specification included in the transmitted signal (SS11).

  The influence range specifying processing unit 10B searches the traceability model storage unit 20C for the traceability model data before the change. Then, the traceability model data before and after the change are compared to determine the changed part. Further, by this change, it is determined whether there is a specification description for the downstream process described in the specification, and further, which description is affected is determined and specified (SS12).

  Further, based on the specification description determined to be affected and the product configuration model data stored in the product configuration model storage unit 20A, the specification in which the specification description is described is further determined and specified ( SS13).

  Then, based on the determined document and the project life cycle model data stored in the project life cycle model storage unit 20B, a task using the document as an input parameter is further determined and specified (SS14). Further, the person in charge who becomes the performer of the determined task is determined and specified (SS15).

  Similar to the first embodiment, the influence range specification processing unit 10B performs settings related to the rework process based on the data of the specified specification description, specification, task, person in charge, etc., and generates data related to the rework process. (SS16).

  The communication processing unit 10C searches the notification data storage unit 20D for the e-mail address of the person in charge specified by the affected range specification processing unit 10B. Then, an e-mail is transmitted based on the e-mail address, and the person in charge who has confirmed the content confirmation (return process occurrence) instructed to change the specification is notified (SS17).

  Based on the instruction from the person in charge, terminal 200 displays the contents of the e-mail on the display means (not shown), and further requests transmission (retrieval) of specifications relating to the change instruction (ST12). The communication processing means 10C transmits a signal including product data based on the request (SS18). The person in charge determines whether to change the specification description based on the displayed content, and gives an instruction to the terminal 200. The terminal 200 determines whether there is a change based on the instruction (ST13), and if there is a change, performs a support process for changing the specification description of the specification by the person in charge (ST11).

  Based on the determination in ST13, the management processing apparatus 10 repeats the above-described processes from SS11 to SS17 for the product data of the specification document in which the specification description has been changed (the product data in the downstream process). . Therefore, this process is continued until the specification description is not changed (until there is no specification description for the downstream process affected by the specification change in the upstream process).

  As described above, according to the system of the second embodiment, when there is a change in the specification description or the like, the influence range specifying processing unit 10B searches the traceability model data storage unit 20C or the like and relates to the change. The product, task, and the person in charge who performed the task (created the product) are identified, and the communication processing means 10C notifies the user by e-mail. On the other hand, notification by electronic mail can be automatically performed by the system. As the person in charge changes the specification description, the influence range in the downstream process and the person in charge are identified, so the influence range can be identified from the upstream process to the downstream process. It is possible to realize a labor saving and prevention of quality deterioration due to omission of reflection of requirements.

Embodiment 3 FIG.
In Embodiment 1 described above, in SS6, the person in charge who performs notification by e-mail is determined in stages, but the present invention is not limited to this. Since all the affected ranges are specified in advance, for example, the communication processing unit 10C may send an e-mail to the affected person at a time.

  In the above-described embodiment, the specification description change of the specification is described. However, the present invention is not limited to this, and can be applied to other deliverables as long as it can be modeled.
