DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technology for managing projects such as system development and program development.
In particular, the present invention relates to a technique for automatically assigning a worker according to a manager's intention to each work of a next project based on past work results of each worker.

[0002]

2. Description of the Related Art In a so-called project management system for defining and managing work contents, work periods, and the like of a plurality of workers involved in a project, it is possible to manage a project in accordance with a project definition.

The conventional project management system collects the work results of the previously executed projects and makes the request by the project manager available so that the work results of the previously executed projects can be used in the next project planning. It is common to display the contents of the work result items that have been performed (for example, JP-A-8-30676). Here, the work performance items are the name of the worker, the work period, the content of the product by the worker, the degree of work delay, the quality, and the like.

By the way, when planning a project,
It is important to assign appropriate workers to each work of a project based on past work performance in order to carry out the project as planned. However, the above-described conventional project management system only collects and displays past work results. Therefore, when assigning workers using such a conventional project management system, it is difficult to assign workers. However, there is a problem that much labor and time are spent. In other words, when assigning workers using the conventional project management system, the project manager displays in the project management system the contents of work performance items that may be necessary for assigning workers. In addition, since the assignment of the worker must be performed in consideration of the content of the displayed work result item, much labor and time are spent on the assignment of the worker.

[0005] In addition to the above-described project management system, a project management system described in Japanese Patent Application Laid-Open No. 9-101987 is conventionally known. When assigning a worker to a certain work, the project management system requests each worker to estimate the completion time of the work, and requests the worker to perform the work with the earliest result of the estimation of the completion time. Like that.

[0006]

Problems to be Solved by the Invention
According to the project management system described in Japanese Patent Laid-Open No. 7, the labor and time required for assigning workers can be reduced. However, since the work request is made to the worker whose estimation of the completion time is the earliest, there is a problem that the work request may be made to the worker who does not follow the intention of the project manager. For example, if you want to select a worker with more emphasis on the quality of the deliverable than on the delivery date, the completion time is slightly later but the quality of the deliverable is lower than that of the worker with better quality, but the completion time A work request is sent to a worker who is early.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a project management system capable of automatically assigning work to workers according to the intention of a project manager. It is in.

[0008]

In order to achieve the above object, the present invention provides a project management server (10 in FIG. 1),
Clients provided for each of a plurality of workers (FIG. 1
20-1 to 20-n), the project management server (10 in FIG. 1) includes a plurality of tasks to be considered when assigning workers. An input means (11 in FIG. 1) for inputting the basic information of the worker assignment including the result item and the priority of each work result item, and the basic information of the worker assignment inputted from the input means (11 in FIG. 1). Based on the information and the work performance of each of the work performance items of the worker, prioritize the past work performance related to the work performance item with a higher priority, and rank the workers in the order of superior work performance, Worker assignment management means (14 in FIG. 1) for performing a process of giving a work request to a client of the worker preferentially from a worker having a higher job order until a worker accepting the work request appears.
The clients (20-1 to 20-n in FIG. 1)
In response to a work request from the project management server (10 in FIG. 1), an operator reply means (22 in FIG. 1) for replying to the project management server (10 in FIG. 1) whether or not the work request can be accepted. ).

In this configuration, when allocating a worker, the input means (11 in FIG. 1) transmits a plurality of work result items and the worker assignment basic information including the priority order of each work result item. Is entered. Worker assignment management means (1 in FIG. 1)
4) The past work related to the work result item having a higher priority is based on the worker assignment basic information input from the input means (11 in FIG. 1) and the work result of each of the work result items of the worker. A worker who accepts a work request by prioritizing the results and ranking the workers in the order of excellent work results, and giving the work request to the client of that worker with priority from the worker with the highest rank Repeat until appears.

Further, according to the present invention, when a certain worker cancels a work request already accepted, the work is automatically assigned to a substitute worker according to the intention of the manager. Each of the clients (120- in FIG. 13)
1-120-n) includes a work postponement cancellation report means (126 in FIG. 13) for sending a work cancellation report to the project management server (110 in FIG. 13) when canceling the accepted work request. Server (Fig. 13
110) is the work postponement cancellation report means (1 in FIG. 13).
26), a strategy management unit (117 in FIG. 13) for receiving the work cancellation report sent from the server, and the worker assignment management unit (114 in FIG. 13) is provided with the strategy management unit (114 in FIG. 13).
117) receives the work cancellation report, the priority order is determined based on the worker assignment basic information input from the input means (111 in FIG. 13) and the work performance of each work performance item of the worker. Prioritize past work results for higher work result items and rank the workers in order of work performance, targeting workers excluding the worker of the client that output the work cancellation report. The process of giving a work request to a client of the worker with priority from the worker with the higher job priority is performed until a worker accepting the work request appears.

In this configuration, when canceling a work request that has already been accepted, the worker must use the client (FIG. 13).
The work cancellation report is sent to the project management server (110 in FIG. 13) using the work postponement cancellation report means (126 in FIG. 13) in 120-1 to 120-n). When the strategy management means (117 in FIG. 13) in the project management server (110 in FIG. 13) receives the work cancellation report, the worker assignment management means (114 in FIG. 13) changes the input means (114 in FIG. 13).
Based on the worker assignment basic information input from (111) and the work results of each work result item of the worker, the past work results of the work result items with higher priorities are prioritized and the workers are performed. Are ranked in the order of superiority, and then, with the exception of the worker of the client that output the work cancellation report, the worker with the highest rank is given priority to the client of that worker. Is performed until a worker accepting the work request appears.

Further, the present invention provides a method for automatically changing a scheduled work period of a work to be performed after the work when it becomes necessary to postpone the scheduled end date of the work. Work delay cancellation report means (126 in FIG. 13)
Is configured to send a work postponement report including the postponed end date to the project management server (110 in FIG. 13) when postponing the scheduled end date of the work that has received the work request, FIG. 13 at 117) shows, when the work postponement report is received, the postponed work to the client requesting a work to be performed after the work reported to postpone the scheduled end date by the work postponement report. A structure is provided for sending a work change request including a scheduled period.

In this configuration, when postponing the scheduled end date of the work for which the work request has been accepted, the work postponement cancellation report means (126 in FIG. 13) sends a work postponement report including the scheduled end date after the postponement. The strategy management means (117 in FIG. 13), which has sent to the project management server (110 in FIG. 13) and received this work postponement report, performs it after the work reported to postpone the scheduled end date by the work postponement report. A work change request including the postponed work scheduled period is sent to the client requesting the work to be performed.

Next, the operation when assigning workers to the work of the currently planned project will be described.

When assigning a worker to the work of the project, the project manager inputs the worker assignment basic information from the input / output means 11. Now, for example, in order to assign a worker to the work of the work type “coding”, the project manager sets the worker assignment basic information 500 shown in FIG.
Is input from the input / output unit 11.

When the worker assignment basic information 500 shown in FIG. 2 is inputted from the input / output means 11, the worker assignment management means 1
Reference numeral 4 denotes a worker who has passed the content “coding” of the work type field 501 in the worker assignment basic information 500 to the project plan management means 13 and has performed work of the work type “coding” in a past project. (Work assignment candidate) is inquired (FIG. 6, S61).

When an inquiry about a work assignment candidate is made, the project plan management means 13 refers to a project plan DB 16 in which past project plans are stored, as shown in the flowchart of FIG. Then, the obtained work assignment candidate name is passed to the worker assignment management means 14 (S71, S72).

In the case of this example, the project plan DB 16
Are the contents shown in FIG. 3, so that S71, S72
Then, the following processing is performed. Worker assignment management means 1
4, when the work type “coding” is passed, the project plan management means 13 refers to the project plan DB 16 in S71, and the worker name field of the record in which the content of the work type field 164 is “coding”. The operator name registered at 168 is obtained. This worker name becomes the work assignment candidate name. Next S7
In 2, the work assignment candidate name obtained in S71 is passed to the worker assignment management means 14. In the example of FIG. 3, there are three records in which the content of the work type field 164 is “coding”, and the worker name fields 168
Contains the worker names "C", "D", "E", "F",
Since “J” and “K” are registered, the project plan management means 13 outputs “C”, “D”, “E”, “F”,
“J” and “K” are sent to the worker assignment management means 14 as work assignment candidate names.

When the work assignment candidate name is sent from the project plan management means 13, the worker assignment management means 14 sends the received work assignment candidate name and the work type field of the worker assignment basic information 500. 501, the work type set in the work result item priority field 504,
The work result item name is passed to the work assignment candidate result management means 12 (FIG. 6, S62). In the case of this example, the worker assignment management means 14 assigns the work assignment candidate names “C”, “D”,
"E", "F", "J", "K", work type "coding", work result item names "total man-hours", "delay degree", "deliverable quality", "deliverable amount", ""Degree of progress" to the work assignment candidate result management means 12.

The work assignment candidate result management means 12 receives the work assignment candidate name, work type,
When the work result item name is passed, as shown in the flow chart of FIG. 8, a work history item (item in the worker history DB 23) required to obtain the contents of the work result item indicated by the work result item name. (S81).

For example, in the work result item name passed from the worker assignment management means 14, the "degree of delay" represented by the following equation (1) is a scale indicating how much the work is delayed with respect to the scheduled work period. Is included, the "work end date" is a work history item required to determine the "delay degree".

Degree of delay = {(work end date−scheduled end date) / (scheduled end date−scheduled start date)} × 100 (1)

That is, in order to obtain the "delay degree",
"Work end date", "Scheduled end date", "Scheduled start date" are required, but "Scheduled end date" and "Scheduled start date" are required.
Are registered in the project plan DB 16 and only the “work end date” is registered in the worker history DB 23. Therefore, the work history items required to obtain the “degree of delay” are “work end date”. Become.

For example, when the work result item name passed from the worker assignment management means 14 includes “total man-hours” indicating the cumulative time spent for the work, the worker history DB 23 Since it can be obtained only by the registered “total man-hours”, the work history item “total man-hours” is the work history item necessary to obtain the work result item “total man-hours”.

As a specific method of obtaining the work history items required for obtaining the contents of the work result items in S81, for example, a method for obtaining the contents in association with each work result item There is a method of preparing a table in which the work history items necessary for the operation are registered, and using the table.

When the process of S81 is completed, the work assignment candidate result management means 12 sets the work assignment candidate "C",
One of the clients “D”, “E”, “F”, “J”, and “K” has the work history item obtained in S81 and the work type passed from the worker assignment management unit 14. By sending "coding", the content of the above-mentioned work history item for the work of the work type "coding" is inquired (S82). Further, in S82, if there is a work history item whose contents need to be inquired due to the field configuration of the work assignment candidate result DB 15, the contents are also inquired. Work assignment candidate result DB
If the fifteen field configuration is as shown in FIG.
The start date, project ID, project name, and work ID of the work of the work type “coding” are queried.

For example, in S82, if the work assignment candidate result management means 12 makes an inquiry to the client 20-C (1 ≦ C ≦ n) of the work assignment candidate “C”, the client As shown in the flowchart of FIG. 9, the worker history management unit 21 in 20-C acquires the contents of the inquired work history items with reference to the worker history DB 23, and acquires the contents of the acquired work history items. And a work history answer including a work ID for specifying the work history item is sent to the work assignment candidate result management means 12 (S91,
S92).

Now, for example, the contents of the worker history DB 23 in the client 20-C are as shown in FIG. 5, and the worker assignment management means 14 sends the work history item "work" of the work type "coding". Assuming that the contents of “work end date”, “total man-hours”, “deliverable quantity”, and “deliverable quality” are inquired, the worker history management unit 21 proceeds to S9
At 1, S92, the following processing is performed.
The worker history management means 21 refers to the worker history DB 23 in S91, and, in the record in which the content of the work type field 234 is “coding”, the work end date field 236, the total man-hour field 237, and the amount of deliverables. The work ID field 233 for acquiring the contents "96/05/25", "110 hours", "20K", and "A" registered in the field 238 and the product quality field 239, and specifying the contents. The contents of "P
1-T3 "and the like. In the next S92, a work history answer including the contents of each field (each work history item) acquired in S91 is sent to the work assignment candidate result management means 12.

The work assignment candidate result management means 12 receives the work history reply including the above contents from the worker history management means 21 in the client 20-C, and is transferred from the worker assignment management means 14. A plan item required to obtain the contents of the work result item indicated by the work result item name obtained is obtained, and if there is such a plan item, the contents are inquired to the project plan management means 13 (FIG. 8, S83). . At that time, the work assignment candidate result management means 1
2 passes to the project plan management means 13 the work ID "P1-T3" included in the above-mentioned work history answer and the name of the plan item whose contents are to be known.

Now, for example, if it is assumed that the work result item name passed from the worker assignment management means 14 includes the “delay degree” defined by the above equation (1),
The work assignment candidate result management means 12 inquires of the project plan management means 13 about the contents of the plan items “scheduled start date” and “scheduled end date” for the work ID “P1-T3”.

The project plan management means 13 receives the work ID “P1-T3” from the work assignment candidate result management means 12.
Plan items "scheduled start date" and "scheduled end date"
When there is an inquiry about the content of the work ID, as shown in the flowchart of FIG.
In the record in which the contents of the field 163 are “P1-T3”, the contents of the scheduled start date field 165 and the scheduled end date field 166 “96/05/05”, “9”
6/05/20 "and sends it to the work assignment candidate result management means 12 (S101, S102).

When the contents of the inquired plan item are sent from the project plan management means 13, the work assignment candidate result management means 12
Based on the contents of the work history item in the work history response already sent from the worker history management means 21 of -C,
The work result items “total man-hours”, “delay degree”, “deliverable quality”, “deliverable amount”, which are set in the work result item priority field 504 of the worker assignment basic information 500,
The content of the "degree of progress" is calculated (S84 in FIG. 8).

Here, the contents of the work history items sent from the worker history management means 21 can be used as they are for "total man-hours", "product quality" and the like. Also,
The “delay degree” includes the contents of the work history item “work end date” sent from the worker history management unit 21 and the plan items “scheduled start date” and “scheduled end date” sent from the project plan management unit 13. It can be obtained by substituting the content of “day” into the above-described equation (1).

At S84, the work result item “total man-hours”,
When the contents of “delay degree”, “deliverable quality”, “deliverable amount”, and “degree of progress” are calculated, the work assignment candidate result management means 12, as shown in FIG.
Each field 1501-1 of the 15th first record
The predetermined information is registered in 513 (S85). "Total man-hours", "Delay degree", "Delivery quality" calculated in S84,
"Delivery amount", "Degree of progress" content "110H", "3
“1%”, “A”, “20K”, and “90%” are the total man-hour field 1509 and the delay degree field 15, respectively.
10, the product quality field 1511, the product quantity field 1512, and the progress degree field 1513 are registered. Also, "R1" is displayed in the result ID field 1501.
In the worker name field 1502, the name “C” of the work assignment candidate currently being processed is indicated, and in the work type field 1503, the work type “coding” currently targeted for worker assignment is indicated by the project ID. A field 1504 includes a project ID “P” as information indicating which project the work result is for.
In the project name field 1505, the project name “A system development” is used as information indicating which project the work result is for, and the work ID is
A field 1506 includes work ID “P1-T3” as information indicating which work the work result is for.
However, in the start date field 1507, the work ID “P1-T
The start date “96/05/05” of the work of “3” and the end date “96/05/25” of the work with the work ID “P1-T3” are registered in the end date field 1508.

The work assignment candidate result management means 12 executes S8
When the process of 5 is completed, it is determined whether or not the above-described process has been performed for all the work assignment candidates (S86). In this example, the work assignment candidates are “C”, “D”,
"E", "F", "J" and "K"
Since the process is performed only for the work assignment candidate “C”, the determination result in S86 is NO.

When the result of the determination in S86 is NO, the work assignment candidate result management means 12 selects the unprocessed work assignment candidates "D", "E", "F", "J", and "K". (S82 to S8)
5). Then, when the above-described processing is performed on all the work assignment candidates (S86: YES), the work assignment candidate result management unit 12 passes the contents of the work assignment candidate result DB 15 to the worker assignment management unit 14. (S87).

When the contents of the work assignment candidate achievement DB 15 are passed from the work assignment candidate achievement management means 12, the worker assignment management means 14, as shown in the flowchart of FIG. The work results (contents of fields 1509 to 1513) of the work assignment candidates “C”, “D”, “E”, “F”, “J”, and “K” passed from
The work assignment candidates “C”, “D”, and “C” are assigned based on the work result item priority set in the work result item priority field 504 of the worker assignment basic information 500 input from the input / output unit 11. "E", "F", "J",
"K" is ranked (FIG. 6, S63). When ranking the work assignment candidates, the worker assignment management means 14 first ranks the work assignment candidates with higher work performance higher based on the work performance of the work performance item with the highest priority. Work assignment candidates. And
If each work assignment candidate can be ranked in a different order based on the work result item with the highest priority, the process is terminated, and if there is a work assignment candidate with the same order, Each work assignment candidate is ranked based on the work result of the work result item of the second priority. If the rank of the work assignment candidate whose rank is the same in the top work result item is different in the work result item of the second priority, the highest work result In the items, the ranks of the workers who have become the same rank are set in the order of the ranks obtained by using the work result items of the second priority, and the process is terminated. On the other hand, if the rank of the work assignment candidate whose rank is the same in the highest-ranked work result item is the same in the second highest-ranked work result item, the third rank is assigned. The ranking is performed using the work result of the work result item of the priority order. Hereinafter, the same processing is performed until all the work assignment candidates are ranked in different ranks.

When the work assignment candidates are ranked in S63, the worker assignment management means 14 sends a work request including the scheduled work period to the client of the work assignment candidate with the highest rank (S64). ). Now, for example, in S63, each of the work assignment candidates is “K”, “E”, “C”,
Assuming that the ranks are ranked in the order of “F”, “J”, and “D”, the worker assignment management unit 14 assigns the candidate “K”
Work request to the client 20-K (1 ≦ K ≦ n).

This work request is received by the worker answering means 22 in the client 20-K. Worker answering means 2
When the work request is received, the work request is passed to the worker schedule management means 24, and an inquiry is made as to whether the work request can be accepted.

Thus, the worker schedule management means 24 refers to the worker schedule DB 25, determines whether or not the work request can be accepted based on the schedule information before and after the scheduled work period, and determines the result of the work. Is returned to the responder means 22. If it is determined that the work is acceptable, the worker schedule management means 24 registers the requested work schedule in the worker schedule DB 25.

If the worker schedule management means 24 determines that the work is acceptable, the worker reply means 22 notifies the worker assignment management means 14 of the project management server 10 that the work is acceptable, and determines that the work is unacceptable. If so, give a notice of non-acceptance.

When the acceptability notification is sent from the client 20-K of the work assignment candidate “K” (FIG. 6, S65: YES), the worker assignment management means 14 sends the work input / output means 11 to the input / output means 11. Outputs the information indicating the work assignment candidate “K” as the worker who assigns the project plan DB 16 using the project plan management means 13.
Then, the fact that the worker “K” has been assigned to the work to be currently assigned is registered (S68). On the contrary,
If an unacceptable notice has been sent from the client 20-K (S65: NO), the client 20-E (1 ≦ E ≦ n) of the second work assignment candidate “E” ranked second.
(S64). And client 2
0-E sends an acceptance notice (S6
5 is YES), the process of S68 is performed, and if an unacceptable notification is sent (NO in S65), the order is ranked third.
Client 20-C of the th work assignment candidate “C”
A work request is sent to (1 ≦ C ≦ n) (S64). Hereinafter, the same processing is performed until a work assignment candidate accepting the work request appears. If the work request is not accepted even if the work request has been sent to all the work assignment candidates (S66: YES), the request is output to the input / output means 11 to notify the project manager of the fact. (S6
7).

Next, the configuration of the worker assignment management means 14 in the project management server 10 will be described, and its operation will be described in detail.

FIG. 11 is a block diagram showing a configuration example of the worker assignment management means 14. Referring to FIG. 11, the worker assignment management unit 14 includes an assignment information acquisition unit 141, a worker ordering unit 142, and a work request unit 143.

The allocation information acquisition means 141 is
When, for example, the worker assignment basic information 500 shown in FIG. 2 is input from No. 1, the work assignment candidate is inquired to the project plan management means 13 to obtain the work assignment candidate name (S61 in FIG. 6). After that, the assignment information acquisition means 14
1 transfers the work type, work result item, and work assignment candidate name to the work assignment candidate result management means 12, and waits for the contents of the work assignment candidate result DB 15 to be sent (S6).
2).

When all the contents of the work assignment candidate result DB 15 are sent, the assignment information acquisition means 141 sends all the contents of each field of the work assignment candidate result DB 15 and the contents of the worker assignment basic information 500. The contents of the work result item priority field 504 are passed to the worker ordering means 142.

As a result, the worker ordering means 142
Rank work assignment candidates. In this ranking,
The worker ordering unit 142 firstly assigns the first priority to the work result item “delay degree” in the work result item priority field 504 in the order of superior work results in the work assignment candidate result DB 15. The record IDs of the records are ranked. When ranking, work performance items that are considered to be superior when their values are small, such as “Delay degree” and “Total man-hours”, are ranked in ascending order, and conversely, the values are Work performance items that are deemed to be superior are ranked in descending order.

In the case of the example shown in FIG.
The values of “delay degree” of the record of “R6” are “31%”, “62%”, “0%”, “36%”, and “4”, respectively.
5% "and" 0% ", the ranking of the result IDs with respect to" delay degree "is (R3, R6), R1, R4, R
5, R2. Here, (R3, R6) is R3 and R
6 indicates the same rank.

In the ranking based on the work result item “delay degree” having the first priority, since there is a result ID having the same rank, the worker ranking means 142 sets the priority to the second. The ranking based on the work results of the work result item “Total man-hours” is performed. In the case of the example of FIG. 4, the “total man-hours” of the records with the result IDs “R1” to “R6”
Are “110H”, “120H”, and “10H”, respectively.
0H "," 150H "," 160H ", and" 90H ".
R6, R3, R1, R2, R4, and R5. In the ranking by the work result item “total man-hours” with the second highest priority, the result IDs “R3” and “R” which have the same rank in the ranking using the work result item with the first priority
6 ”could be placed in a different order, and the worker ordering means 142 assigns a priority to the order of the result ID obtained based on the work result item“ delay degree ”with the first priority. The order of the result ID is determined by reflecting the order obtained based on the second-ranked work result item “total man-hours”. In other words, the ranks of “R3” and “R6” having the same rank determined based on the work performance item “degree of delay” are determined in the order (R6,
R3), the result ID is R6, R
The order is 3, R1, R2, R4, R5.

When the work IDs are ranked in the order of R6, R3, R1, R2, R4, and R5, the worker ordering means 142
Indicates the worker name registered in the worker name field 1502 in each record of the work assignment candidate result DB 15;
The results are ranked according to the rank of the result ID. Therefore, the ranking of work assignment candidates is “K”, “E”, “C”,
The order is "F", "J", and "D".

Thereafter, the worker ranking means 142 determines the ranking results of the work assignment candidates “K”, “E”, “C”,
“F”, “J”, and “D” are passed to the work request means 143.

As a result, the work requesting means 143 sends the client 20- of the work assignment candidate “K” with the highest rank.
A work request is made to K (FIG. 6, S64). And
When the acceptability is notified from the client 20-K (S65: YES), the process of S68 is performed. When the acceptability is notified (S65: NO), the work assignment candidate “E Is requested to the client 20-E (S64). Hereinafter, the work request means 14 is repeated until a client accepting the work request appears.
3 performs the same processing. However, even if the work request is made to all of the work assignment candidates, but no work assignment candidate accepts the request (S66: YES), the fact is output to the input / output means 11 (S67).

Next, the configuration of the worker history management means 21 in the client 20-1 will be described, and the processing performed by the worker history management means 21 will be described in detail.

FIG. 12 is a block diagram showing an example of the configuration of the worker history management means 21. The worker history inquiry receiving means 211, the worker history database management means (worker history DB management means) 212, , Work time monitoring means 213
And a product evaluation means 214.

The worker history DB management means 212 in the worker history management means 21 sends the work ID of the work requested by the project manager to the work time monitoring means 213, and determines the start time and end time of the work. Ask to be monitored.

The work time monitoring means 213 stores the worker history D
The start time at which the work with the work ID received from the B management means 212 is started and the end time at which the work is ended are monitored. As a method of monitoring the start time and the end time, for example, the following method can be used.

When a project manager requests a worker to perform a task, application software (for example, word processor software of company A) used for the task and a file name (for example, X system) handled by the application software are used. (Specification.TXT) is specified, and the start time is when the file name of the application software is used for the first time on the client 20-1. Further, when the administrator requests the worker to perform the work, the application software (for example, e-mail software of Company B) that reports the end of the work, and the file name (for example, X System specifications.TX
T) is designated, and the time when the application software transmits the attached file to the administrator on the client 20-1 is defined as an end time.

The work time monitoring means 213 sends the start time and the end time obtained as described above to the worker history DB management means 212.

When the work requested by the administrator is completed,
The worker history DB management means 212 is a
4, the work ID of the completed work is sent, and a request is made to evaluate the result of the work.

The product evaluation means 214 evaluates the product of the received work ID. From the viewpoint of evaluation, there are the quantity of the product and the quality of the product. As a method of evaluating the product, for example, the following method can be used.

The amount of deliverables measures the amount of files generated by the application software used in the work. The amount of deliverables depends on the nature of the work being targeted. For example, when the work is specification creation or the like, the deliverable is a document, and the amount of the deliverable is the number of pages of the finished work. If the work is coding or the like, the product is a source code, so the amount of the product is the number of lines of the product after the work.

Since it is difficult to automatically calculate the quality of the product from the product, when the end of the work is detected by the work time monitoring means 213, the worker who made the product is directly inquired. An assessment of the quality of the deliverable:
There are three-level evaluations by operators.

The product evaluation means 214 sends the evaluation result of the product obtained as described above to the worker history DB management means 212.

The worker history DB management means 212 stores the start time and the end time obtained from the work time monitoring means 213,
The product evaluation result obtained from the product evaluation means 214 is registered in the worker history DB 23.

The worker history DB 23 in which various information is registered as described above is stored in the project management server 10.
Is used as follows from the work assignment candidate result management means 12.

The work assignment candidate result management means 12 sends the work type to be inquired to the worker history inquiry receiving means 211 in the client of the work assignment candidate and the work history item name.

The worker history inquiry receiving means 211 sends the work type and the work history item name to the worker history DB management means 212 to inquire about the work history of the work type.

The worker history DB management means 212 acquires a work history answer from the worker history DB 23 and sends the acquired work history answer to the worker history inquiry receiving means 211.

Thus, the worker history inquiry receiving means 21
1 sends the work history answer to the project plan management means 13 of the project management server 10.

The worker schedule management means 124 has the functions of the worker schedule management means 24 shown in FIG. It has a function of changing the contents of the worker schedule DB 125 according to the request.

Next, the operation of this embodiment will be described.

A project manager wants to assign a worker to a task in a currently planned project.
In the case where the worker assignment basic information 500 as shown in FIG. 2 is input from the input / output unit 111, in this embodiment,
The same processing as that of the embodiment shown in FIG. 1 is performed, and a worker according to the intention of the project manager is assigned to the above work.

[0100] If the worker who has assigned the work can perform the work as planned, no problem occurs, but sometimes it becomes difficult for the worker who has assigned the work to process the work, or It may be difficult to complete the work within the scheduled work period. In the present embodiment, when such a situation occurs, the following measures are taken in order to automatically take measures such as assigning a substitute worker.

Now, for example, the client 120-K (1
It is assumed that the worker “K” of ≦ K ≦ n) cannot process the requested work. In such a case, the worker “K” of the client 120-K sends a work cancellation report to the project management server 110 using the work postponement cancellation report means 126. The work cancellation report includes the worker name “K”, the work ID of the work whose request is to be canceled, and the work type.

The work cancellation report from the client 120-K is received by the strategy management means 117 in the project management server 110.

[0103] The strategy management means 117
Upon receiving the work cancellation report from 0-K (FIG. 14, S1)
41), a proxy worker assignment request is passed to the worker assignment management means 114 (S142). The substitute work assignment request includes the worker name “K”, the work ID, and the work type included in the work cancellation report.

Upon receiving the substitute worker assignment request from the strategy management unit 117, the worker assignment management unit 114 receives information indicating the work (work assigned to a substitute worker) for which the work request has been canceled (work cancellation report in progress). Input request for input of worker assignment basic information including the work ID, work type, etc.
11 is output.

When a request for inputting basic worker assignment information is output to the input / output means 111, the manager assigns the same basic worker assignment basic information as input when assigning a worker to the work whose work request has been canceled. Input from the input / output unit 111.

When the worker assignment basic information is input from the input / output means 111, the worker assignment management means 114 performs the same processing as in S61 of FIG. To get from. Now, for example, as work assignment candidate names, “C”, “D”, “E”,
It is assumed that “F”, “J”, and “K” have been acquired.

Thereafter, the worker assignment management means 114 performs the same processing as in S62 of FIG. 6, and waits for the contents of the work assignment candidate result DB 115 to be sent from the work assignment candidate result management means 112.

Next, the worker assignment managing means 114 stores the work assignment candidates “C”, “D”, “E”, “F”, and “J” excluding the worker “K” who has canceled the work request. Ranking is performed for the target. The specific method of this ranking is
This is the same as the method described in S63 of FIG.

Thereafter, the worker assignment management means 114 performs the processing shown in S64 to S68 shown in FIG.
Send a work request to the substitute worker.

For example, assume that the worker "K" of the client 120-K cannot complete the requested work within the scheduled work period. In such a case, the worker of the client 120-K uses the work postponement cancellation report means 126 to
Send the work postponement report to 10. This work deferral report includes
It includes the worker name “K”, the work ID of the work whose work period is to be postponed, the work type, and the scheduled work end date after the postponement.

The work postponement report from the client 120-K is received by the strategy management means 117 in the project management server 110.

The strategy management means 117 is the client 12
When the work postponement report from 0-K is received (FIG. 14, S1
41), the work ID of the work following the work (postponed work) indicated by the work ID in the work postponement report, the worker name,
An inquiry is made about the scheduled work period (S143).

In response to this inquiry, the project plan management means 113 refers to the project plan DB 116 and obtains a work ID, a worker name, and a planned work period following the delayed work. Then, the acquired information is passed to the strategy management unit 117.

When the above information is passed from the project plan management means 113, the strategy management means 117 changes the scheduled work period of all the work following the postponed work. As a method of changing the scheduled work period, for example, the following method can be considered. Of all the work following the postponed work, the scheduled start date of the work to be performed first is the next day of the scheduled work end date included in the work postponement report, and the planned end of the work to be performed first above The day is added to the scheduled start date by the original scheduled work period. Similarly, in the work after the first work to be performed, the scheduled work period is similarly sequentially shifted.

In addition to the above-described method, for example, of all the works following the postponed work, only the planned work period of a certain work is shortened, and the planned work period of the other work is not changed. There is also a way to do this.

When the postponed work schedule period is obtained as described above, the strategy management means 117 uses the project plan management means 113 to
Then, the scheduled work period of the postponed work and the work following it is changed (S145).

After that, the strategy management means 117 sends a work change request including the changed work schedule period and work ID to the client of the worker who has requested the work whose postponed work period has been postponed (S146). .

Worker answer means 122 in the client
Upon receiving a work change request from the project management server 110, the schedule of the work whose scheduled work period has been changed and registered in the worker schedule DB 125 using the worker schedule management means 24 is described in the content of the work change request. Change according to.

Although not described in the above embodiment, when determining whether or not to accept a work request from the project management server 110 by the worker schedule management means 124, the work schedule is considered in consideration of the importance of the work. A decision may be made whether to accept the request. In other words, when a work request is sent from the project management server 110, if the scheduled work period included in the work request overlaps with the scheduled work period of the work already scheduled in the worker schedule DB 125, the request is made this time. If the work performed is higher in importance, the current work request is accepted, an acceptability notification is sent to the project management server 110, and the contents of the worker schedule DB 125 are changed. In addition, for the already scheduled work whose scheduled work overlaps with the currently accepted work, the work postponement cancellation reporting means 1
26, the work ID of the work is passed, and a request to send a work cancellation report to the project management server 110 is made. In response to this request, the work postponement cancellation report unit 126 sends a work cancellation report to the project management server 110. The importance of the work request may be set by the project manager, or may be determined on the client side based on the work type.

In the above-described embodiment, when a work cancellation report is sent from a client, the project manager is caused to input the worker assignment basic information again. All of the worker assignment basic information is stored in the input / output means 111, and the worker assignment basic information on the work for which the work cancellation report has been sent is selected from the information and passed to the worker assignment management means 114. Can also. In this case, however, it is necessary to provide the worker assignment basic information with a work ID field in which a work ID is set, in addition to the fields 501 to 504 shown in FIG. That is, in order to select the worker assignment basic information corresponding to the work for which the work request has been canceled from all the worker assignment basic information stored in the input / output unit 111, the canceled work and the worker Since it is necessary to associate the basic information with the assignment, it is necessary to add a work ID field in the basic information on the worker assignment.

[0121]

As described above, according to the project management system of the present invention, when a manager gives a priority to a work result item, a work having a better past work result with respect to a work result item having a higher priority is given. Workers are ranked higher in the rank order, and workers with higher ranks are given priority to send requests to their clients. Assignments can be made automatically.

Further, since the present invention is provided with a work postponement canceling means and a strategy managing means, if a worker who cancels a work request that has already been accepted appears, a proxy work according to the intention of the manager is performed for the work. In addition, when a worker who needs to postpone the scheduled work end date appears, the scheduled work period of the work to be performed after the work can be automatically changed.
