Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to management of design and development projects for products such as hardware and software, and more particularly to a project management system for supporting project schedule management.

[0002]

2. Description of the Related Art In a design and development project of a product such as hardware or software, the progress of the project may be delayed due to various causes. When such a delay occurs, generally, many resources are temporarily invested in the form of support in an attempt to comply with the deadline or delivery date at the time of planning. Such support may help the backed projects recover their delays and meet planned deadlines or deadlines, but from the perspective of the backing resources, the work they do in their primary work Time is wasted, delaying the original work of the supporters, causing them to input resources from another place to comply with their deadlines,
The support chain may be repeated.

In order to avoid such a situation, appropriate project management is required. That is, the purpose of project management is to eliminate delays in design and development projects and to comply with deadlines and delivery dates at the time of planning. As described above, delays in a design and development project arise from various circumstances. For example, there may be cases where the estimate of the initial initial plan is rough, or where disturbance such as jumping in while the project is in progress consumes the resources of the original project work and hinders the progress of the work. it can. Because the former is a problem of the accuracy of the initial plan, it is important to carefully examine the plan when making the initial plan and make an accurate estimate.

[0004] In the latter case, it is necessary to perform appropriate rescheduling when the situation changes, such as when a disturbance occurs. Relying on manual rescheduling increases the effort of the project manager to collect the latest status of the environment where the project is located, and also consumes the manpower of the designers to collect the latest progress. Will be. In particular, when one design and development staff is in charge of a plurality of design development projects, the man-hours spent on the progress management of the project manager and the design and development staff can be enormous.

On the other hand, as a system for supporting planning and progress management of a product manufacturing plan, there is known a production management system in a production line as disclosed in JP-A-6-266413. This system aims at shortening the time for creating a processing schedule while lots having different priorities or importance flows in a production line in a mixed manner. This system is composed of an offline scheduler that creates a long-term processing schedule up to the delivery date for lots with high priority or importance, and an online scheduler that creates a short-term processing schedule for all lots. After the long-term processing schedule is created, the online scheduler creates the short-term processing schedule, so that an accurate processing schedule based on the long-term schedule can be generated in a short time. It is possible to predict the completion date.

[0006]

In order to use such a conventional technique, the steps to be performed must be clarified in the form of a process chart, and detailed attributes such as the required time must be defined. However, in a design and development project, the process to be performed (hereinafter referred to as a work process) is unclear, and since the work process is a work that depends on people, the time required for the work (hereinafter, work man-hours or It is generally difficult to obtain an accurate value of (called man-hour).
Furthermore, since the work process and work man-hours are inaccurate, the accuracy of long-term planning such as delivery date prediction by means corresponding to the above-mentioned conventional offline scheduler is reduced. That is, even if high-precision scheduling is performed from information with low accuracy, a high-precision result cannot be obtained.
From the above, it is difficult to use the above conventional technology for design and development project management.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a project management system suitable for performing a schedule management for a project whose work process is unclear or in which it is difficult to obtain an accurate value of work man-hours at the time of planning.

Next, the operation of the design and development project management system according to the present invention will be described in detail.

(1) Overall Flow FIG. 7 is a diagram showing a processing flow in the design and development project management system according to the present invention. As shown in the figure, when a new project is generated for the development of a new product due to a model change or the development of an order (S21), an initial plan is prepared to start the new project (S22). At this point, product specifications, development budget, etc. have been determined. In the planning step S22, first,
Define the project that outlines the project, such as start date, development deadline, and delivery date. Next, enumerate and define the work processes required for the development of the target product specifications, create a plan from the amount of work obtained, evaluate the plan, and make necessary corrections to make the final Determine a development plan.

Next, a project operation is started based on the plan created in the planning step S22 (S2).

Each staff member steadily performs the given work and proceeds with the project. Each person in charge reports the progress of the work as well as the performance of the work. Managers can manage the progress and if there are any issues in the progress of the project plan,
As a countermeasure, change the plan necessary to comply with the development deadline and delivery date. When all the work required for design development is completed, the design development project is completed (S2).
4).

Next, the planning step S22 and the planning start step S23 will be described in detail.

(2) Flow of Processing in Planning Step S22 FIG. 8 is a diagram showing a flow of processing in the planning step S22. As shown in the figure, a planning step S22
Consists of a project definition step S51, a work process definition step S53, and a plan evaluation / decision step S55.

The program for implementing the planning step S22 is stored in advance in the external storage device 331 of the work computer 32.
When the administrator starts the planning work by using the input unit 325 or the like and starts the program, the program is loaded into the memory 322 and executed by the CPU 321. Also, this program (and the program described below) is installed in advance in an external storage device such as a hard disk,
It is recorded on a recording medium such as a floppy disk or a CD-ROM and provided to each user.

(A) Project Definition Step S51 First, the project definition step S51 will be described. The project definition step S51 is a step for defining a project attribute. The project attributes refer to a project name, a start date, a completion date, a product type to be developed, and the like. This project attribute data
Normally, the administrator uses the input means 325 or the like in the work computer 32 to input. The input attribute data is temporarily stored in the memory 322 or the external storage device 331 and displayed by the display unit 326. Reference numeral 52 in FIG. 8 shows an example of a screen displayed on the display unit 326 of the work computer 32 in the project definition step S51. The project attribute input by the administrator is transmitted to the communication network 33 according to the instruction from the administrator.
Through the execution project data D on the server computer
B43. That is, they are stored in the corresponding columns of the project list storage area 4301 and the product format list storage area 4302, namely, “project name”, “project start date”, “project completion date”, and “format name”. The “project code” is a unique code for identifying a project, and is automatically generated and assigned by the system at the time of project definition.

(B) Work Process Definition Step S53 Next, the work process definition step S53 will be described.
The work process definition step S53 is a step of generating all work process groups necessary for performing development satisfying the required specifications. That is, it lists the study work to be performed for the development of the required specifications and the products such as drawings and documents to be created. In the list-up work at the time of such initial planning, the manager uses his / her own work computer 32 to store the work data stored in the standard work process data and the project performance data DB 42 stored in the standard project data DB 41. The necessary work process data can be acquired from the actual project data and used. Reference numeral 54 in FIG. 8 shows an example of a screen when listing work steps required for a project for which a plan is being prepared.

When using the standard work process data stored in the standard project data DB 41, the work computer 32 changes the names of all the standard project data to the master management data of the standard project data DB 41 in accordance with an instruction from the administrator. The data is sequentially acquired from the data storage area 4101 and displayed by the display unit 326.

Next, from among the displayed standard project names, using the project code of the standard project data selected by the administrator using the input means 325, the product format name and the work belonging to the selected project are used. Product name master storage area 4 for process name and standard man-hour
102 and the work process master storage area 4103 are retrieved and acquired, and displayed by the display unit 326.

In this list-up work,
Instead of the standard project data, actual project data in the project actual data DB 42 may be used. When the administrator instructs to use the actual project data, the work computer 32 obtains all or a part of the actual project data names stored in the project list storage area 4201 of the project actual data DB 42. Then, it is displayed by the display means 326. Next, when the administrator uses the input means 325 to select desired actual project data from the displayed actual project data names, the manager uses the project code of the selected actual project data to respond. The type name, the work process name and the work plan man-hour to be searched are obtained from the product format list storage area 4202 and the work process list storage area 4203, and are acquired.
6 is displayed.

Further, if not only the standard project data DB 41 and the project performance data DB 42 but also the same type of project is currently in progress, the listing work may be performed using the execution project data DB 43.

As described above, the administrator sets the standard project data DB 41 and the project performance data DB 4
The work process group created by using 2 or the like is stored in the work process list storage area 4303 of the execution project data DB 43 via the communication network 33.

As described above, according to this system, standard project data provided by the system and past project data provided by the system can be used even for design and development projects in which necessary work processes and exact man-hours are unclear in advance. Since necessary work processes can be enumerated using actual results, necessary design considerations, drawings, and the like become clear at the initial planning stage, and a highly feasible initial plan can be drafted.

(C) Plan Evaluation / Decision Step S55 Next, the plan evaluation / decision step S55 will be described. The plan evaluation / decision step S55 is a step of creating a plan for the work process group listed in the work process definition step S53. Specifically, the start date and the completion date of each work process are determined. In addition, the amount of work required for the project is grasped from the total man-hours of the listed work process groups, and evaluation is performed by referring to the man-hour load accumulation for each person in charge.
Assignment that is reasonable in man-hours. The assignment of each work process to each person in charge in the present system is performed in the personal data storage area 4304 of the execution project data DB 43.
This is performed by associating the personal code of the person in charge stored in the work process list with the personal code of the person in charge stored in the work process list storage area 4303.

The administrator evaluates and decides such a plan using his / her own work computer 32.
In the plan evaluation / decision step S55, when the manager uses the input unit 325 or the like to input a start date, a completion date, a person in charge, or the like of each work process, the display unit 326 is displayed based on the input data. , A bar chart of the work process for each person in charge and a stack of man-hour loads are displayed to assist the manager in making a decision. Reference numeral 56 in FIG. 8 shows an example of a screen displaying a plan and a pile of man-hour loads by a bar chart.

The work process bar chart uses the planned start date and the planned completion date of each work process stored in the work process list storage area 4303, and the total man-hour is the sum of the work plan man-hours of each work process. And calculate. Here, if the accumulated man-hour load exceeds the practicable amount of the individual, that is, if excessive work is allocated, the manager judges that the plan cannot be performed and starts the schedule. Modify the date, scheduled completion date and person in charge as appropriate. The corrected result is immediately reflected on the display of the display unit 326. As a result of the evaluation of the plan and necessary modifications, when the manager determines that an appropriate plan has been created, all the project data is stored in the execution project data DB 43 via the communication network 33, You have to wait for the project plan.

(3) Process Flow of Plan Execution Step S23 FIG. 9 is a diagram showing a flow of the process of plan execution step S23. As shown in FIG.
Is a work order instructing step S601, a result / progress data collecting / registering step S604, and a determining step S60.
6, a man-hour modification step S608, and a plan change step S609.

The program for realizing the plan execution step S23 is stored in advance in the external storage device 331 of the work computer 32 of each worker, and when the plan is executed, each worker uses the input means 325 or the like. Then, when the program is started, the program is loaded into the memory 322 and executed by the CPU 321.

(A) Work Order Instruction Step S601 First, the work order instruction step S601 will be described. The work order instructing step S601 is a step of instructing a work process assigned to each person in charge on a plan and a start order thereof. In step S601, a list of tasks to be performed is displayed and instructed to the person in charge.

In the work order instructing step S601, first, the person in charge of using the work computer 32 is
For example, detection by login name to the system,
Using the person in charge as a key, the execution project data DB
Forty-three work process list storage areas 4303 are searched, and data (work process name, scheduled start date, scheduled completion date, priority, etc.) relating to the work process group assigned to the person in charge is acquired. The acquired data relating to the work process is temporarily stored in the memory 322 or the external storage device 331.

Next, the retrieved work process groups stored in the memory 322 are sorted by priority, and work instruction screens are generated by arranging the work processes in the order of work date with the closest completion date and displayed on the display means 326. Reference numeral 602 in FIG. 9 shows an example of such a work instruction screen. Based on this work instruction screen, the person in charge recognizes the work he or she is to perform at the moment and implements the work.

In the example screen 602, when the operator selects a work process to be executed from now on using the input means 325, the work computer 32 uses the selected work process as a key to execute the execution project data DB 43. To retrieve the work product of the work process. Further, an application (for example, an editing tool) associated with the product file is automatically started to enable editing of the product. For example, if the work process “Completion of A drawing” is selected in the screen example 602, A
The CAD tool used to create and edit the drawing is automatically started, the file of the A drawing is opened on the screen and can be edited, and the person in charge can perform the drawing work.

(B) Result / Progress Data Collection / Registration Step S604 Next, the result / progress data collection / registration step S604 will be described. The result / progress data collection / registration step S604 receives input of the result and progress data of the work actually performed by the person in charge, and executes the execution project data D.
This is a step of registering in B43.

Result / Progress Data Collection / Registration Step S6
In 04, first, in order to collect the work time and progress of each person in charge of the work, the display means 326 displays a screen for inputting the work results in units of days for each work process, for example, as shown in FIG.
605 is displayed. In other words, the work computer 32 searches the work process list storage area 4303 of the execution project data DB 43 for the work process assigned to the person in charge, using the person in charge as a key. Is displayed on the display means 326. On the other hand, when the person in charge inputs the operation time of performing the operation and the degree of progress of the operation process (for example, what percentage of the total operation amount is advanced) using the input unit 325, the input is performed. The data is temporarily stored in the memory 322, and further,
Via the communication network 33, the “work execution man-hour” and the “degree of progress” which are storage areas corresponding to the work process list storage area 4303 of the execution project data DB 43 are stored.

(C) Determination Step S606 Next, the determination step S606 will be described. The determination step S606 is a step of comparing the progress to be achieved in the plan with the actual progress based on the work status of the person in charge, and determining whether or not each work process is being performed as planned. Therefore, in the determination step S606, means for calculating the actual progress and means for calculating the progress target value are provided.

FIG. 10 is a diagram showing a configuration for realizing the determination step S606. As shown in the drawing, the determination step S606 is performed by the actual / progression degree acquiring unit 701,
Progress degree storage means 702, actual start date / completion date / man-hour storage means 703, man-hour accumulated value storage means 704, plan acquisition means 705, plan start date / completion date / planned man-hour storage means 706, progress calculation This is realized by means 707, actual progress value storing means 708, progress target value storing means 709, and comparative evaluation means 710. Here, each storage means:
It temporarily stores data for calculation and comparison determination, and is constituted by a memory 322 and an external storage device 331. Each processing unit is realized by loading a program stored in the external storage device 331 in advance into the memory 322 and executing the program by the CPU 321.

In determination step S606, first,
The progress acquiring unit 701 reads the “progress”, “actual start date”, and “actual completion date” for each work process from the execution project data DB 43 via the communication network 33.
, "Work execution man-hours" and "work cumulative man-hours" are retrieved and acquired, and the progress storage means 702, the actual start date / completion date / man-hour storage means 703, and the accumulated value storage means 7 are respectively obtained.
04. Further, the plan acquisition unit 705 executes the execution project data DB via the communication network 33.
From “43”, a “scheduled start date”, a “scheduled completion date”, and a “work plan man-hour” for each work process are retrieved and acquired, and stored in the planned start date / completion date / plan man-hour storage means 706.

Next, the progress calculating means 707
The actual progress value and the progress target value are calculated by using the progress degree, the work execution man-hour, the work accumulation man-hour and the work plan man-hour for each work process stored in 02, 703, 704 and 706,
These are stored in the actual progress value storage means 708 and the progress target value storage means 709, respectively. Here, the “actual progress value” is a value indicating the current degree of progress of the work process. The “progress target value” is a value that indicates the degree of progress up to the present time (for example, today), which is planned in the plan. The comparative evaluation means 710 compares the actual progress value and the progress target value stored in the actual progress value storage means 708 and the progress target value storage means 709, respectively, to determine whether or not the work process is delayed. I do. If it is determined that the work process is not delayed, the process is terminated. On the other hand, if it is determined that the work process is delayed, the process proceeds to the next man-hour correction step 608. At this time, the delayed work process may be notified to a manager or a person in charge.

Here, an example of a method of calculating the actual progress value and the progress target value performed by the progress calculating means 707 will be described. Note that the calculation method of the actual progress value and the progress target value is not limited to the following method, and an appropriate method is selected in mounting.

For example, when a certain work process is examined on a certain day (hereinafter referred to as “today”), it is assumed that the standard man-hour = 11 Hrs, the actual time = 10.5 Hrs, and the degree of progress = 80%. . Here, Hrs is an abbreviation of Hours and is a unit representing time. In this case, as a simple calculation method, the degree of progress input by the person in charge may be used as the actual progress value as it is. That is, actual progress value = [degree of progress] = 80%. In addition, the following may be considered.

[0066]

## EQU00001 ## Actual progress value = [actual time] / [standard man-hour] = 95.5% In this way, the progress calculating means 707 sets the actual progress value =
Calculate as 80% (or 95.5%).

On the other hand, the progress target value is calculated as follows, for example.

[0068]

[Equation 2] Progress target value = [actual work day from plan start date to today] / [actual work day from plan start date to plan end date] The actual progress value and progress target value calculated as described above are calculated. In comparison, if [actual progress value] <[progress target value], determination step S606 determines that the work process is “delayed”.
Is determined.

(D) Man-hour correction step S608 Next, the man-hour correction step S608 will be described. The man-hour modification step S608 is a processing step that is executed when it is determined that a delay has occurred in the determination step S606, and dynamically corrects a work plan man-hour originally not so high in accuracy according to the implementation situation. This is a processing step for approaching a realistic value.

FIG. 11 is a diagram showing a configuration for realizing the man-hour correction step S608. As shown in the figure,
The man-hour modification step S608 is performed by the selected mapping storage unit 801.
A mapping designation unit 802, a mapping group storage unit 803,
Man-hour correction means 804 and correction plan man-hour storage means 805
And the planned man-hour registration means 806. Each of the storage units 801, 803, and 805 stores data for processing, and includes a memory 322 and an external storage device 331. In addition, each processing unit is realized by a program stored in advance in the external storage device 331 or the like being loaded into the memory 322 and executed by the CPU 321.

In the man-hour modification step S 608, first, the man-hour modification unit 804 uses the data acquired and calculated in the determination step 606 and the mapping relation that defines the modification method stored in the selected mapping storage unit 801. The man-hour is corrected and stored in the corrected planned man-hour storage unit 805.

Next, the planned man-hour registration means 806 transmits the execution project data DB via the communication network 33.
The modification man-hours stored in the modification man-hour storage means 805 are registered and stored in the storage area 43 of “work plan man-hours”.

The mapping relation stored in the selected mapping storage means 801 is determined by the mapping designating means 802 from a plurality of mappings stored in the mapping group storage means 803.
This is a selected / specified mapping. Also, the mapping group storage means 8
03, a plurality of mappings are prepared in advance by the system. The mapping designation means 802 includes a mapping group storage means 803.
An appropriate one is selected from the plurality of mappings stored in the storage area according to the characteristics of each project or work process.
Further, a different mapping may be selected for each person in charge. In this case, it is possible to change the method of correcting the planned man-hour depending on the ability and experience of each person in charge.

Here, an example of a method of correcting the planned man-hour will be described with reference to 607 in FIG. The “correction pattern” described in 607 in FIG. 9 corresponds to the “mapping (relation)” described above.
Corresponds to. Here, a case where a proportional function is used as the mapping will be described. In this case, since the graph of the correction pattern is a linear function passing through the origin, the planned man-hour after correction is calculated as follows.

[0075]

[Equation 3] Planned man-hours after modification = [actual time] / [progress] = 10.5 / 0.8 ≒ 13.2 Hrs In other words, in this case, the planned man-hour is changed from 11 hours to 13.2.
Correct on time.

Thus, the man-hour correction step S60
In No. 8, the planned man-hours can be dynamically approached to a more realistic value by dynamically modifying the planned man-hours according to the actual progress.

(E) Plan Change Step S609 Next, the plan change step S609 will be described. The plan change step S609 predicts the completion date of the project based on the corrected planned man-hours and the progress of the design and development work. If a delay is predicted, a work process is performed to prevent the project from being delayed. This is a processing step of changing the priority of the project, or, in some cases, modifying the start date of the work process of another project, thereby changing the project plan.

FIG. 12 is a diagram showing a configuration for realizing the plan change step S609. As shown in the figure, the plan change step S609 includes a DB interface 901, a plan change unit 902, and a delay amount prediction unit 9
03, completion date prediction means 904, and remaining man-hour calculation means 90
5, a start / completion date / priority storage unit 906, a deadline storage unit 907, a man-hour storage unit 908, a remaining man-hour storage unit 909, a predicted completion date storage unit 910, and a delay amount storage unit 911. Is done. In addition, each storage means,
The memory 322 and the external storage device 331 are used temporarily for processing. Each processing unit is realized by loading a program stored in advance in the external storage device 331 into the memory 322 and executing the program by the CPU 321.

In the plan change step S 609, first, the DB interface 901 reads the execution project data DB 43 from the execution project data DB 43 through the communication network 33.
The start date, completion date and priority of each work process, the number of man-hours, and the project deadline are acquired and stored in the start / completion date / priority storage unit 906, the man-hour storage unit 908, and the deadline storage unit 907, respectively. .

Next, the remaining man-hour calculation means 905 calculates the remaining man-hours for each project based on the work man-hours for each work process, the start date and the completion date, and today's date, and stores the remaining man-hours in the remaining man-hour storage means 909. .

Next, the completion date prediction means 904 predicts the completion date for each project using the remaining man-hours for each project stored in the remaining man-hour storage means 909 on the basis of today, and predicts the completion date for each project. Predicted date complete completion date storage means 9
10 is stored.

Next, the delay predicting means 903 calculates the delay amount from the difference between the project deadline stored in the time limit storing means 907 and the project completion date stored in the predicted completion date storing means 910, The predicted delay amount is stored in the delay amount storage unit 911. If a delay is predicted, the administrator or the like may be notified at this time or at an appropriate timing.

Next, the plan change unit 902 acquires the start date, the completion date, and the priority from the start / completion date / priority storage unit 906, and obtains the start date, the completion date, and the priority from the estimated delay amount stored in the delay amount storage unit 911. Calculate the start date and priority for each work process, change the priority of work processes, and in some cases, modify the start date of other projects so that the deadline of the project can be complied with. Change the plan automatically. Finally, the DB interface 901
Via the communication network 33, the execution project data DB 43, the start date of each changed work process,
Register and store the completion date and priority.

In the present system, it is not a special case such as when a problem occurs in the discretion of the manager or the process, but when the actual man-hour or the work progress is set for each work process, or
At a predetermined time interval, the work plan man-hour is corrected, and the project is re-planned based on the corrected work plan man-hour.

As described above, according to the present system, the means for dynamically modifying the work plan man-hours is provided, so that the planned man-hours having a low initial accuracy can be changed to a higher precision based on the implementation status. , Can be modified to a realistic planned man-hour. Further, when the delay of the project is predicted due to the modification of the planned man-hour, the system changes the plan necessary to achieve the original purpose. Therefore, the necessity for the administrator to maintain the schedule plan while sequentially considering the latest situation is reduced, and the man-hour for the plan management can be reduced. Further, since the progress information is collected by the system, it is easy to collect the progress information, and the labor of both the manager and the person in charge is reduced.

Further, in the present system, the work plan man-hours corrected to realistic values are stored in the execution project data DB 43.
And the contents of the execution project data DB 43 can be used as project performance data and the like for estimating the number of man-hours at the time of the initial planning, thereby improving the accuracy of estimating the number of man-hours at the time of the initial planning. In other words, for a design and development project to be carried out for the first time, each work man-hour is set to a value appropriately estimated by the administrator, the project is executed, and when the same design and development project is carried out for the second time, the above work man-hour is corrected. By reusing the obtained project performance data, the accuracy of man-hour estimation at the time of the initial planning can be improved.

[0087]

As described above in detail, according to the present invention, the accuracy of estimating the number of man-hours for each work process at the time of planning is low, and even if the number of man-hours varies greatly depending on the person in charge, During the course of the project, the planned man-hours are automatically corrected according to the progress of the project, so even if the predetermined man-hours are different from the actual ones, problems can be discovered early and the Measures based on simple decision making.

Further, according to the present invention, the man-hours are changed based on the current work progress, and the plan is automatically changed using the corrected man-hours. The man-hours can be reduced, and the progress management man-hours that are burdensome for both the manager and the person in charge are reduced, so that the manager concentrates on the project management that is the original work, and the person in charge concentrates on the design work can do.
