Therefore, there is a method of evaluating and managing the quality of the deliverable (see Patent Document 1, for example).

Japanese Patent Laying-Open No. 2005-085016

  As described above, if the work of the next process cannot be performed until the deliverable meets the standard, it is highly likely that the development of the project will be delayed if it is delayed somewhere, and that much time will be spent. In addition, even if the product satisfies the standard at that time, it is later changed by a request or the like, and often undergoes a rework process. As described above, it is necessary to manage the deliverables throughout the entire life cycle while estimating and evaluating the quality. In addition, it is difficult to uniformly evaluate the quality of the deliverable with only one value.

Embodiment 1 FIG.
FIG. 1 is a block diagram showing a system configuration centering on a product management apparatus according to an embodiment of the present invention. In FIG. 1, the product management apparatus 1 includes a management processing device 10, a storage device 20, and a communication device 30. The management processing device 10 is a device for processing and managing various data related to a development project, for example. In the present embodiment, file format data related to deliverables and process plans (hereinafter referred to as deliverable data and process plan data) is processed, and data is generated by performing conversion based on three models described later, The data is stored in the storage unit 20. And, for example, if there is a change in the deliverable data, the range affected by the change (developer who may perform a rework process and modify the deliverable, etc. (hereinafter referred to as the person in charge)) And data related to the rework process is generated according to the settings related to the rework process. Here, it is assumed that the management processing apparatus 10 according to the present embodiment includes a model conversion unit 10A, a cost storage processing unit 10B, an index calculation processing unit 10C, and an index display processing unit 10D.

  The model conversion means 10A, for example, based on product data and process plan data included in a signal transmitted via the network 100 or the like, a product configuration model (description content (form) of a product, form) described later. A process for converting and generating data (which becomes an instance) based on a model of a product such as a parent-child relationship), a project life cycle (process plan) model, and a traceability (traceability) model. Then, the data related to the conversion is stored in each storage unit of the storage device 20. As a result, the system according to the present embodiment can model (to the specification level of the product) and manage (store) the data described by the rules according to the model. For example, the flow from the upstream process to the downstream process related to software development can be grasped by the flow between specifications, and the flow (relationship) between specifications is traced from the downstream side to the upstream side. It can be carried out.

  The cost storage processing unit 10 </ b> B causes the storage unit 20 to store data relating to various costs included in a signal transmitted from the terminal 200 via the network 100. In the present embodiment, it is assumed that the traceability model storage unit 20 </ b> C stores it in order to associate with the specifications related to the deliverable. Based on the data stored in the storage device 20, the index calculation processing unit 10C calculates an index for product evaluation to be managed. Here, in the present embodiment, for example, the index calculation processing means 10C is assumed that all development costs such as technical difficulty level, understanding level of the person in charge, skill level, and the like can be converted into money via the amount of work time. Is to calculate an index based on data relating to monetary cost (hereinafter referred to as cost). Further, the index display processing unit 10D performs a process of creating a display signal for causing the terminal 200 to display the cost stored in the storage device 20 and the calculation result performed by the index calculation processing unit 10C, for example.

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

  The storage device 20 is a device for temporarily or long-term storing data necessary for the management processing device 10 to perform processing and various data relating to a project. In particular, in the present embodiment, the storage device 20 includes at least a product configuration model storage unit 20A, a project life cycle model storage unit 20B, a traceability model storage unit 20C, and a product data storage unit 20D. . The product configuration model storage unit 20A, the project life cycle model storage unit 20B, and the traceability model storage unit 20C each store data related to each model converted and generated by the model conversion unit 10A. Here, as described above, the cost for creating each product is also stored in the traceability model storage unit 20C. Details of the cost to be stored will be described later. The deliverable data storage means 20D stores, for example, deliverables created by each person in charge (developer) in the project as data. Although not particularly limited here, the storage device 20 may be configured by a plurality of physically different devices.

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

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

  The system according to the present embodiment performs data management, index calculation, and display so that quality management, evaluation, and the like of a product can be performed based on an index calculated from a cost. For this reason, various costs included in a signal transmitted from the terminal 200 via the network 100 are stored in the storage device 20. Based on the stored cost, the index calculation processing means 10C calculates the index and stores it in the storage device 20. Further, the index display processing unit 10D performs a process for displaying the calculated index in time series together with the index calculated in the past, and transmits a display signal based on the process to the terminal 200. By performing the above processing in the management processing apparatus 10, the time series change of the index is visually displayed on the terminal 200.

  FIG. 2 is a diagram illustrating a change in cost over time. In the system according to the present embodiment, it is possible to visually display the cost on the terminal 200 with the graph as shown in FIG. 2 by the processing of the index display processing means 10D. As shown in FIG. 2, in this embodiment, the actual cost, the planned work cost, the request change corresponding cost, the defect removal cost, and the design change corresponding cost are represented. The actual cost represents the ratio of the actual cost to the budget. The actual cost represents the accumulated (accumulated) actual cost stored in the storage device 20 (hereinafter, the same applies to other costs). Then, the sum of the planned work cost, the requirement change response cost, the defect removal cost, and the design change response cost becomes the actual cost. By storing these data in the storage device 20, it becomes possible to grasp the quality of the product, the usage of each cost before the baseline, the operating environment, and the like.

  The planned work cost is a cost spent for work before the baseline. Here, the baseline (reference line) is a product that has been approved as an official version through work (review and creation) (here, it is assumed that the product is approved). Further, the request change corresponding cost is a cost spent for changing a deliverable based on a request for addition of a customer regardless of the baseline. Here, the request change corresponding cost does not include a cost related to a change based on a change or the like of another deliverable, and is a cost when the change originates.

  The defect removal cost is the cost spent to remove the extracted (pointed out) defect (design change by the project member, design error, etc.) regardless of the baseline. For example, before the baseline, it is the cost spent on removing defects extracted during reviews during the planned work period, and after the baseline, the cost spent on removing defects such as specifications that originated the rework process. It becomes. In addition, the cost corresponding to the design change is a cost spent for changing the deliverable based on the change of the deliverable, the specification, etc. performed in the upstream process regardless of the baseline. Since the cost at the time of the change is included in the request change response cost and the defect removal cost, the design change response cost is a cost related to a change based on a change of other deliverables.

  For example, as shown in FIG. 2, the trend (trend) related to the use of the cost can be grasped by showing the time-series change of the cost. For example, in FIG. 2, the actual cost tends to increase even after the baseline. In addition, defect removal costs are also increasing. However, the request change response cost and the design change response cost have not increased. From this, it can be seen that the increase in the actual cost is mainly caused by the increase in the defect removal cost. Therefore, it is highly possible that the product has an inherent defect, and the defect continues to be exposed as time passes (as the process proceeds to the downstream process). Therefore, this product has low quality. Further, even in the reworking process performed to remove the defect, there is a high possibility that the review or the like is insufficient and the defect has not been completely removed.

  FIG. 3 is a diagram showing the display contents by the processing of the index display processing unit 10D according to the first embodiment. As shown in FIG. 3, in the present embodiment, five types of performance / budget ratio cost index, review cost index, defect removal cost index, change-corresponding cost index, and overtime ratio cost index are indices related to cost.

  The actual / budget ratio cost index represents the ratio of the actual cost to the budget. The review cost index represents the ratio of the cost spent for performing the review to the actual cost in the work related to the deliverable. For example, before the baseline, the costs spent on reviews during the planning period are mainly, and after the baseline, it is spent on reviews related to the rework process that originated the changes in deliverables, specifications, etc. Cost is the main.

  Further, the defect removal cost index represents a ratio of the defect removal cost to the actual cost. The change-corresponding cost index represents the ratio of the cost spent on corrections made in response to changes in specifications and the like to the actual cost throughout the life cycle of the deliverable. Here, the spent cost is the sum of the request change response cost and the design change response cost. The overtime ratio cost index represents the ratio of the overtime cost to the actual cost of the person in charge assigned to creation, review, correction, etc. of the deliverables.

  For example, each cost is accumulated with time in the life cycle of the deliverable (not reduced). Therefore, it is desirable for the above-mentioned graph of each cost index that the increase of each index after the baseline is as small as possible in order to proceed with the project.

  For this reason, a point in time before the baseline (which is easier to compare than the baseline is assumed to be the baseline point here) and a point after the baseline for quality estimation (hereinafter referred to as the base point). The quality of the product can be estimated on the basis of the value of each cost (after the line), the change in the graph, and the relationship with the graph in the upstream process.

  For example, at the time of the baseline, the result that the actual / budget ratio cost index, the review cost index, and the defect removal cost index are significantly lower than the predetermined target (not shown) (the review time and the defect removal work time are short). Suppose that For example, if this state continues throughout the life cycle, it can be assumed that the quality of the deliverable is high. For example, when the defect removal cost index significantly increases after the baseline, it can be estimated that the review was not successful even if the review time was short before the baseline. Conversely, if a result that is significantly lower than the target is obtained at the time of the baseline, it is possible to consider measures for improving the quality in advance, such as checking a review record.

  Also, for example, if there are many defect removal cost indicators or change-response cost indicators in the deliverables (specifications) of the upstream process, but the change-response cost indicator does not increase, respond to changes in the upstream process, etc. It can be inferred that the reviews and changes made may not have been made properly. Therefore, if the project is continued as it is, it can be determined that there is a possibility of deteriorating the quality of the deliverable. In addition, when only the change-corresponding cost index is large, it can be determined that there may be a problem in the quality of the deliverable in the upstream process and the project itself. As described above, the quality of the deliverable can be estimated.

  As described above, in the product management apparatus according to Embodiment 1, the index calculation processing unit 1C calculates the index based on at least the data before and after the baseline, and the index display processing unit 10D calculates the index. Since the product is managed by performing the process of displaying the index on the terminal 200, the product can be managed through the life cycle.

  In addition, since data related to monetary cost is used as the data used for calculating the index when calculating and displaying the index, the product such as skill level, technical difficulty, work time, energy, etc. of the person in charge An index can be calculated from data obtained by converting the elements in the creation with a scale of money, and the quality of the product can be estimated and evaluated. Furthermore, since each index is displayed in a time-series graph by the processing of the index display processing means 10D, it is possible to manage the deliverables throughout the life cycle based on the index. In particular, by visually expressing changes before and after the baseline, it is possible for a developer, for example, to easily evaluate quality estimation, evaluation, improvement measures, and the like of a product.

Embodiment 2. FIG.
FIG. 4 is a diagram showing the display contents by the processing of the index display processing means 10D according to Embodiment 2 of the present invention. In the above-described first embodiment, each index is represented in time series. In the present embodiment, for example, the index display processing unit 10D performs processing so that two indexes at the time of performing the quality estimation target before and after the baseline are displayed at the same time. In this way, two radar charts are displayed.

  Further, as described above, a target value for each index may be determined in advance and displayed. For example, as described above, each cost can be stored in the storage device 20. By accumulating each cost, for example, if it is possible to grasp as a quantitative indicator the cost distribution before the baseline of the deliverable that has been exposed to low quality, the operating environment of the person in charge, the target value for each indicator It can be determined in advance. Based on the target value, it is possible to set a baseline, predict a factor of quality deterioration inherent in the product before the baseline, and the like, and perform early quality improvement.

  By displaying the indicators before and after the baseline on the radar chart, depending on the indicators, the size of the area inside each of the indicators connected by a line can also help the quality estimation and evaluation.
