BACKGROUND OF THE INVENTION
The present invention relates to a method and system for managing the development work of various products in the manufacturing industry, a program for managing the development work, and the like, and mainly belongs to the field of work management technology using a computer.
[0002]
[Prior art]
The development of various commercial products in the manufacturing industry begins with the planning, goes through each process of design policy and design specification decision, rough design, detailed design, primary trial production, mass production trial production, etc., and then shifts to mass production However, after the development is completed and the production is shifted to mass production, various defects and improvements are often found at the manufacturing site and the market until the life cycle of the product is completed. In this case, the specifications and design are reviewed, and design work, prototype work, etc. will be performed again with this, but such review of the design etc. after the completion of development causes a significant increase in cost, As a result, the company's competitiveness is hindered.
[0003]
For such a situation, at the stage of design development, an attempt has been made to suppress the design change after mass production as much as possible with the aim of developing a product with as high a completeness as possible. A design support system using such a computer is disclosed.
[0004]
In other words, based on the design specifications, this support system reflects the design requirements extracted in advance by the design evaluator, the cases of problems that require design changes in the past product development, and solutions to them. In addition to creating electronic files as requirement information and registering them in the server, for specific design work, the requirement information corresponding to the design specifications is extracted from the server and presented to the designer. Detailed design is done by referring to the item information.
[0005]

[Problems to be solved by the invention]
In the system disclosed in the above publication, since the requirements for the design, past defects, and examples of design changes to the design are reflected at the time of designing, it is expected that the degree of completion at the time of final drawing will be improved. it can.
[0006]
However, in order to do so, it is necessary for the evaluator to point out the requested items to the design specification without omission, and if the person in charge is immature and the indication is insufficient, the design change after drawing or after mass production is required. Will be invited. In addition, since it is assumed that there are many examples of design changes in the past, if this is insufficient, improvement in the completeness of the design drawings cannot be expected, and the design must be reviewed after drawing or after mass production. .
[0007]
Therefore, by introducing quantitative management related to design changes, the present invention realizes development with a high degree of perfection even if there is no skilled evaluator or there are many cases of design changes of similar products. The challenge is to make it possible.
[0008]
[Means for Solving the Problems]
In order to solve the above problems, the present invention is configured as follows.
[0009]
  First, the invention according to claim 1 of the present application is a development management for managing the completeness of product development work.systemRelated toThere,Design change target number setting that sets the target number of design changes during the development period and the target number of design change indications for each phase based on the number of design changes expected to occur during the life cycle of the development target product in advance.meansAnd setting target number of design changesmeansDesign change record that records the design changes that occurred during the development period of the above products for each phasemeansDesign change indication record that records design change indications that occurred during the development period of the above products for each phasemeansAnd the above design change recordRecorded in the meansSet the actual number of design change phases and the number of design change targetsmeansDifferences between the target number of design changes for each phase and the design change indication recordRecorded in the meansSetting the actual number of design change indications for each phase and setting the target number of design change indicationsmeansDevelopment completion indication that displays the difference from the target number for each phase of design change indication set inmeansAnd the phase progress to proceed to the next phaseWith meansIt is characterized by that.

  That is, thissystemIn the life cycle from product planning to development and transition to mass production and then withdrawing from the market, development such as new development or improvement development depending on the product field This is based on the knowledge that an almost constant number of design changes will occur depending on the mode, and the number of design changes that are expected to occur during the entire life cycle period will be executed as early as possible during the development period. , Trying to improve the degree of completion of development.
[0011]
  This will be described with reference to FIG. 27. Conventionally, as shown by a broken line, there has been a need for design changes distributed over each period from planning to mass production transition (end of development) to the end of the life cycle. However, many of these design changes were predictable at the development stage. Therefore, based on the number of design changes that are considered to be almost constant throughout the entire life cycle period, the target number to be executed during the development period is set, and the target number and the actual number of design changes during the development period are determined. I tried to compare them. This changes the design as shown by the solid line in FIG.TheExecute ahead of schedule during developmentdo it,Completeness at the end of product developmentTheImprovementIt becomes possible to make it.
[0012]

Therefore, for example, when the number of design changes is insufficient, it can be considered as a shortage of actual design changes, an insufficient number of indications, or a shortage of both. It is possible to select an optimal one as a mode of managing the degree of completion.
[0014]
  In addition, the target number is set for each phase during the development period, and the difference between the design change indication and the target number of the design change and the actual number is displayed for each phase. When it is judged that there is, it becomes possible to end the phase by the phase progress means and proceed to the next phase, and thereby, it is finely managed whether or not a predetermined number of design changes have been pointed out or design changes have been made. As a result, the degree of completion at the end of development will be further improved.

[0047]
Furthermore, the change notification table records the contents etc. when the design change for which the change instruction is given is completed and the contents are notified to the related department (specifically, when the design change notice is created). As shown in FIG. 9, the change instruction code that is the source of the notification, the code of the project, and the notification were made using the change notification code automatically given when the change notification was executed as a key. The phase and date, the department and name of the notifier, the element code of the component to be notified, the purpose of notification, the content of notification, and the reason for notification are recorded.
[0048]
Next, the operation of the system by the program recorded in the program recording unit 13a in the recording device 13 of the server 10 will be described.
[0049]
First, when a new development project is launched, for example, if a project manager or the like (hereinafter referred to as “manager or the like”) accesses the server 10 from his / her client 21, the network 20 is connected from the communication control device 16 of the server 10. Then, a Web screen signal is transmitted to the client 21, and a new project registration screen W1 shown in FIG. 10 is displayed on the display device. Therefore, the administrator or the like inputs the name and code of the project to be newly launched on this screen W1 and the model code of the development target product of the project.
[0050]
Further, the administrator or the like inputs the components of the development target model of the current project on the model configuration registration screen W2 shown in FIG. 11 displayed on the display device of the client 21 next. That is, based on the model code already input on the screen W1, the names of the units constituting the current product and the names of the parts belonging to each unit are input while forming a directory structure.
[0051]
Further, the administrator or the like designates the phase of the development process set in the current project on the development phase registration screen W3 shown in FIG. 12 displayed on the display device of the client 21 next, and for each phase. Enter the scheduled date for the end event.
[0052]
Further, the administrator or the like, on the change target number registration screen W4 shown in FIG. 13 displayed on the display device of the client 21 next, for each component of the development target model set as described above and the development phase Set the target number of design changes for each. In this case, the target number is set according to the target product of the project or according to the development mode such as new development or improved development. This target number is a target value of the number of actual changes to be executed, and for example, 1.5 times the target number of change indications.
[0053]
As described above, on the screens W1 to W4 sequentially displayed on the display device of the client 21, data relating to the project, data relating to the components of the development target model, data relating to the development phase, and changes input by the administrator or the like Data relating to the target number is all transmitted to the server 10 via the network 20, and the project table of FIG. 3 and the model component table of FIG. 4 provided in the data recording unit 13 b of the recording device 13 in the server 10. , And recorded in the development phase table of FIG. 5 and the change target number table of FIG. Thereby, the setting at the time of starting a new project is completed.
[0054]
Next, the operation of the system at the time of design change in the development process after project startup will be described.
[0055]
Now, for example, in the design specification creation phase, it is assumed that there is a need for design change (specification change) for a certain part. In this case, a designer or a general manager of design (hereinafter referred to as “designer etc.”) becomes a change indicator and accesses the server 10 from his / her client 21 to point out the change.
[0056]
Then, if a predetermined input operation such as project designation is performed on the Web screen transmitted from the server 10, a model component screen W5 shown in FIG. 14 is displayed, and the model component shown in FIG. 4 is displayed on this screen W5. Each component of the development target model of the project read from the table is displayed in a directory structure. Therefore, the designer or the like now designates the unit name or part name of the component for which the change is pointed out. In addition, it is separately specified that the current operation is an operation for indicating change.
[0057]
Note that the current phase is displayed at the top of the model component screen W5 as shown by the arrow a.
[0058]
If the component designated on this screen W5 is, for example, a (part) processing circuit of a (unit) display, the unit name and part name are displayed on the next change indication creation screen W6 shown in FIG. The Then, on this screen W6, the designer or the like inputs the date of change indication, his / her department, name, design change purpose, content and reason. In addition, when there is image data indicating a change location or the like, the storage destination path in the recording device 13 of the server 10 is input.
[0059]
These data are recorded in the change indication table of FIG. In that case, the change indication code is automatically assigned and recorded, and the date of the date is automatically recorded as the change indication date, and the affiliation and name of the designer as the change indication person are used. Is automatically read and recorded from the name list registered in advance, and the value of the completion flag is not yet instructed to execute the change and has not been rejected. , “0” is recorded.
[0060]
In this way, when a designer or the like points out a change in any component in any phase, the contents and the like are sequentially recorded as new records in the change indication table.
[0061]
On the other hand, an administrator or the like who decides whether or not to execute the indicated change confirms what kind of change is pointed out periodically or at an appropriate time.
[0062]
That is, by accessing the server 10 from its own client 21 and performing a predetermined operation such as specifying the model component to be confirmed on the above-described model component screen W5, as shown in FIG. The change status screen W7 on which the design change status of the component, for example, the (part) processing circuit of the (unit) display is displayed is displayed.
[0063]
The change status screen W7 includes a list of items that have been pointed out by designers, a list of items for which change instructions have been issued for change points, and a change notification that indicates the completion of changes to the change instructions. The list of items for which the item has been performed is displayed with the corresponding items arranged side by side, with the date and the name of the person in charge. Therefore, the administrator or the like selects one of the change indication items for which no change instruction is given.
[0064]
Thereby, the change instruction screen W8 shown in FIG. 17 is displayed, and the contents recorded in the change indication table of FIG. 7 for the change indication item on this screen W8, for example, (unit) display- (part) processing For the circuit, the change purpose, change content, change reason, etc., which the designer etc. input on the change indication screen W6 of FIG. 15 are displayed. Further, the image data is read from a predetermined storage location in the recording device 13 of the server 10 in accordance with the path recorded in the change indication table and displayed as an image on the change instruction screen 8.
[0065]
Therefore, the administrator or the like confirms the contents and images displayed on the screen W8 and determines whether or not to execute the indicated change. When instructing execution of the change, the change instruction button b is clicked. Thereby, the data related to change indication on the screen W8 is recorded in the change instruction table of FIG. 8 as data related to the change instruction.
[0066]
In that case, the change instruction code is automatically assigned and recorded, the date of the change is automatically recorded as the change instruction date, and the affiliation and name of the administrator as the change instruction By identifying, it is read out from the pre-registered name list and automatically recorded, and the value of the completion flag is recorded as “0” because no change has been executed yet for the instruction. At this time, “1” indicating that there is a change instruction is recorded in the field of the completion flag of the record of the change indication item in the change indication table of FIG.
[0067]
Note that when the administrator or the like rejects the indicated change, the administrator clicks the change rejection button c on the screen W8. In this case, a new record is not created in the change instruction table of FIG. 8, but “1” is recorded in the completion flag column of the change indication table of FIG.
[0068]
Next, the designer who made the change indication confirms whether or not there has been a change instruction from the manager or the like for the change indication made by himself / herself.
[0069]
That is, when the server 10 is accessed again and a predetermined operation such as designating a component to be changed is performed, the above-described change status screen W7 shown in FIG. 16 is displayed. As described above, the list of change indication items is displayed on this screen W7. When a change instruction is given for the change indication, an instruction is displayed in the change instruction column corresponding to the change indication. The date and the name of the instructor are displayed, indicating that there has been a change instruction for the change indication. Then, if the change instruction item corresponding to the change indication on the screen W7 is selected, the change notification screen W9 shown in FIG. 18 is then displayed, and the screen W9 is read from the change instruction table of FIG. The contents of the change instruction, the image read from the storage location specified by the path, and the like are displayed. When the change indication is rejected, the fact is displayed on the change status screen W7.
[0070]
When there is a change instruction, if the contents, images, etc. are displayed on the change notification screen W9, the designers should confirm that the contents etc. correspond to the contents of the change indication pointed out by themselves. Check. And if the confirmation is made, this change notification screen will be displayed after making necessary changes such as correcting the specifications or correcting the drawings in accordance with the changes pointed out by the manager or the like. Click the change notification execution button d in W9.
[0071]
At this time, a change notification creation screen W10 shown in FIG. 19 is displayed, and the contents of the change instruction read from the change instruction table of FIG. 8 are displayed on this screen W10, as with the change notification screen W9. This screen W10 is a screen in which the display content can be edited. The designer or the like confirms the display content and performs necessary edits or clicks the completion button e as it is.
[0072]
As a result, as shown in FIG. 20, a change notification form in which the display content of the change notification screen W10 is entered is automatically created, and the content of the screen W10 is recorded in the change notification table of FIG. In that case, the change notification code is automatically assigned and recorded, the date of the change is automatically recorded as the date of change notification, and the affiliation and name of the designer etc. as the change notification By identifying, it is read from a pre-registered name list and automatically recorded. At this time, “1” indicating that there is a change notification is recorded in the completion flag column of the record of the change instruction item in the change instruction table of FIG.
[0073]
Then, the design change notice is filed or distributed to a department that needs work for reflecting the change, and the design change is completed.
[0074]
As described above, in each development phase, the design change indication, the instruction to execute the design change in response to the indication, and the notification that the design change has been executed in response to the indication are performed by the unit or part of the development target model. Etc., and are recorded in the change indication table, change instruction table, and change notification table shown in FIGS. Then, the number of executions of these change indications or change notifications is compared with the target number set at the start of the project for each phase and each component, and the development completeness of the component in that phase is confirmed. Is displayed.
[0075]
In other words, for example, assuming that the current time is in the design specification creation phase and that the (part) processing circuit of the (unit) display is displayed as the degree of completion, the above components are indicated on the model component screen W5 of FIG. First, on the change indication result screen W11 shown in FIG. 21, the preset target number of change indications of the component, the actual number of change indications up to the present time, and the difference between them are shown in a table and a graph. Is displayed. In this case, the target number is set to, for example, 1.5 times the target number for the phase and the component read from the change target number table in FIG. 6, and the actual number is the change indication in FIG. The number of records recorded in the table is counted and displayed for each phase and each component.
[0076]
Further, in the change notification result screen W12 of FIG. 22, the target number of change notifications of the constituent elements set in advance, the actual number of change notifications up to the present time, and the difference between them are the above-described change indication result screen W11. Similarly, it is displayed in a table and a graph. In this case, the target number is the target number for the phase and the component read from the change target number table in FIG. 6, and the actual number is recorded in the change notification table in FIG. The number of records is counted and displayed for each phase and each component.
[0077]
Here, the display such as “72/75 / −3” in the tables of the screens W11 and W12 indicates the actual number “72” with respect to the target number “75” and the difference “−3”.
[0078]
Administrators, etc., read the results screens W11 and W12 and read the difference in the number of change indications and the number of change notifications for each component in the relevant phase. If the difference is large, there is still room for change. In many cases, it is judged that the development has not been completed sufficiently, and the designer is requested to further review the design. On the other hand, if the difference between the number of change indications and change notifications with respect to the target number is sufficiently small, or more than the target number, the development of that component in the relevant phase is considered to be sufficiently completed. to decide.
[0079]
If it is determined that the completeness of all the constituent elements is sufficient, it is determined that the phase has been completed, and a predetermined phase end event is executed. Then, the process proceeds to the next phase. The progress of this phase is performed by clicking the phase progress button f on the phase progress screen W13 shown in FIG.
[0080]
In this way, according to the system, since the development phase is advanced while judging the degree of completion for each component of the development target model, when all phases of the development period are finished and the production phase is shifted to mass production, As a whole, a high degree of perfection has already been achieved. Therefore, the number of design changes after the shift to mass production is significantly reduced.
[0081]
In addition, in the change status screen W7 of FIG. 16, together with the graph showing the degree of completion similar to the performance screens W11 and W12, as described above, in the phase at that time, the date of indication for each change item, The date of the change instruction for the indication and the date of the change notification for the instruction are displayed side by side. Therefore, by referring to this screen W7, the progress of design change work from indication to change notification through change instruction is displayed, and it is possible to respond to the delay. Further, at the end of each phase, the delay in the progress of the development work is also determined by comparing the date at that time with the scheduled date of the end event recorded in the development phase table of FIG.
[0082]
Further, in the change indication table, change instruction table, and change notification table, for each change item, together with the code of the target component and the executed phase, the purpose, content of change indication, change instruction or change notification, Each reason is recorded and used as a reference for future development work.
[0083]
That is, on the search screen W14 shown in FIG. 24, one or more search targets are specified from change indication, change instruction, and change notification, and any of model, unit, part, and phase is required as an attribute. If so, the record of the change item having the specified attribute is searched from the table corresponding to the specified search target, and displayed in a list on the search result screen W15 shown in FIG.
[0084]
For example, if a change notification is specified as a search target and a model is specified as an attribute, a list of all change notification items for that model will be displayed on the screen W15. If the model, unit, and phase are specified, the change notification items in the specified phase for the model and unit are displayed in a list.
[0085]
Then, if any of the items displayed on the screen W15 is selected, for example, if the item is a change notification item, then the change notification detail screen W16 shown in FIG. 26 is displayed. Displayed in detail. When a change indication item is selected or a change instruction item is selected, a change indication detail screen or a change instruction detail screen similar to the screen W16 is displayed.
[0086]
Therefore, it is possible to improve the efficiency of the development work by using the design change information for the development work in the subsequent project or other projects. In that case, since it is possible to specify the model, unit, or component indicated by the part and the development phase, etc. as the search item attributes, for example, past changes in the specific part, or past in the specific phase Search can be performed by narrowing down the attributes as in the modification example, and the necessary design change information can be obtained efficiently.
