Description

  The present invention relates to a development process improvement effect evaluation apparatus, evaluation method, and evaluation program, and more particularly to a development process improvement effect evaluation apparatus, evaluation method, and evaluation program for improving the development process improvement effect evaluation accuracy.

  As for the conventional development process, ISO 15504 and the like based on models such as CMMI (Capability Maturity Model Integration; capability maturity model integration) and ISO 12207 (Software Lifecycle Process) have become international standards in advance (for example, see Non-Patent Document 1). ). In addition, these standards are one index for carrying out the development process depending on the organization or project.

  Here, in the CMMI shown in Non-Patent Document 1, a development process is defined as a “process area”, a “goal” is set for each process area, and a “practice” that further refines the “goal” is set. . In ISO 12207, “activity” is set for each process, and “task” in which “activity” is detailed is set. In CMMI, process areas can be classified into those related to organizations and those related to projects.

  In addition, with regard to conventional development risk evaluation methods, for example, PMBOK (registered trademark) (project management knowledge system) shows a method using risk occurrence probability and risk impact as parameters. Is also shown (for example, see Non-Patent Document 2).

  As for conventional general business process improvement, for example, a method of setting and monitoring KPI (Key Performance Indicator) for a subdivided business is shown (for example, refer to Non-Patent Document 3).

  Furthermore, conventionally, a method for determining a risk evaluation scale from a project plan and a project performance has been shown (see, for example, Patent Document 1). Conventionally, a method for determining whether to import an activity into the project management process based on skills, experience, and risk data based on new technology for each activity of ISO12207 has been shown (see, for example, Patent Document 2).

  By the way, when trying to improve the development process in a project or organization, it is important to present and explain the cost-effectiveness of the development process improvement. For example, conventionally, if the required level of the standard development process such as CMMI is executed as it is depending on the project to be improved and the situation of the organization, the development cost is expected to increase. Therefore, conventionally, it is necessary to present and explain a development process improvement plan that has a well-balanced cost-effectiveness.

  However, development process evaluations such as CMMI maturity level and ISO 15504 capability level are evaluations of the development process itself and cannot explain cost effectiveness. For this reason, conventionally, a sufficient budget for development process activities cannot be obtained, which is a limitation of process improvement activities such as quality improvement, delivery time reduction, and productivity improvement.

  In order to overcome these situations, we can formulate and execute cost-effective process improvement plans by presenting and explaining cost-effectiveness quantitatively, promoting process improvement, quality improvement and delivery time. It is necessary to shorten and improve productivity.

  Here, the technique as shown in Patent Document 1 described above determines a risk evaluation scale from a project plan and a project performance. However, in the above-described method, since the risk evaluation scale is determined based on the correlation with the trouble record, there is a possibility that a risk such as “the probability of occurrence is low, but if it occurs, the damage becomes enormous” may be missed. Moreover, in the above-mentioned method, since there is no description about risk countermeasures, the countermeasures cannot be evaluated.

  Furthermore, the method as shown in Patent Document 2 described above determines whether to import into the project management process based on risk data for each activity of ISO 12207 and input data that is a risk basis. Because there is no description of the cost-effectiveness of the results, process improvement cannot be evaluated.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a development process improvement effect evaluation apparatus, an evaluation method, and an evaluation program for improving the evaluation accuracy of the development process improvement effect. To do.

  In order to solve the above-described problems, the present invention employs means for solving the problems having the following characteristics.

  The present invention relates to a development process improvement plan setting means for setting an improvement plan for a development process for each organization or project for development in an evaluation apparatus for evaluating an improvement effect of a development process due to a development risk, and the development process improvement plan. Risk estimation setting means for estimating risk based on improvement plan data set by the setting means, cost data and risk data set in advance, and risk data obtained by the risk estimation setting means are converted into cost risk, quality Risk cost conversion means for converting at least one of the risk and delivery date risk into cost, and cost effectiveness corresponding to the improvement effect of the development process is obtained based on the cost obtained by the risk cost conversion means Effect cost acquisition means, and the effect cost acquisition means And having an evaluation result output means for outputting the evaluation result based on the calculation result is.

  Further, the present invention provides a development process improvement plan setting step for setting an improvement plan for a development process for each organization or project for development in an evaluation method for evaluating an improvement effect of a development process due to a development risk, and the development process The risk estimate setting step for estimating the risk based on the improvement plan data set by the improvement plan setting step, the cost data and the risk data set in advance, and the risk data obtained by the risk estimate setting step are converted into cost risk Cost risk step corresponding to the improvement effect of the development process based on the cost obtained by the risk cost conversion step for converting at least one risk into a cost among the quality risk and the delivery date risk, and the cost obtained by the risk cost conversion step To get the effective cost And having a flop, and the evaluation result output step of outputting the effective cost acquisition evaluation result based on the calculation result obtained by the step.

<Block configuration example of evaluation device for development process improvement effect>
First, a development process improvement effect evaluation apparatus according to the present embodiment will be described with reference to the drawings. FIG. 1 is a diagram illustrating an example of a block configuration of an evaluation apparatus according to the present embodiment. The evaluation device 10 shown in FIG. 1 includes a development process improvement plan setting unit 11, a goal achievement addition setting unit 12, a risk estimate setting unit 13, a risk cost conversion unit 14, an effect cost acquisition unit 15, and an evaluation result output.

The evaluation apparatus 10 also includes a gap table 21, a project table 22, a cost file 23, a development process improvement plan input screen file 24, a target achievement additional input screen file 25, an achievement required cost table 26, and a risk estimate. An input screen file 27, a risk cost conversion table 28, an effect file 29, and an achievement effect table 30 are included.

  In the example of FIG. 1, development process improvement is evaluated in detail up to CMMI practices. This corresponds to, for example, a task of ISO12207 or Automotive SPICE. Therefore, as another embodiment, for example, it can be evaluated by a task of ISO12207 or Automobile SPICE.

  Here, in the evaluation apparatus 10 shown in FIG. 1, first, an achievement target level of the development process (for example, CMMI maturity level 3 or ISO 12207 capability level 3) is set, and a required practice to be evaluated is determined. Information that clarifies the gap with the current state of practice is created, and the information is stored in the gap table 21.

  For example, data input to the gap table 21 is provided with an output means such as a display or an input means such as a keyboard, a mouse, or a touch panel in the evaluation apparatus 10, and a user or project manager of the evaluation apparatus 10 (user). However, it is possible to input using the input means while looking at the screen of the display. Further, the gap table 21 may be obtained from an external device that can be connected to the evaluation apparatus 10 via a communication network such as the Internet or a LAN (Local Area Network) and can transmit and receive data.

  Next, the development process improvement plan setting means 11 in the evaluation apparatus 10 reads the gap table 21 described above, and further develops, for example, a development process improvement plan for each practice and personnel / tool based on the input development process improvement plan data. Estimated indicators, etc., estimated costs, estimated man-hours, etc. are set. The development process improvement plan data includes, for example, “plan”, “estimated index”, “estimate”, and the like, but is not limited to this in the present invention. Further, the development process improvement plan data may be input by the user using an input unit or the like, or may be acquired from an external device or the like.

  Here, the estimated man-hour set in the development process improvement plan setting means 11 is converted into a cost using, for example, data of the project table 22. Further, the development process improvement plan setting means 11 totals the converted costs and stores the results in the cost file 23. Further, the development process improvement plan setting means 11 stores the set setting data in the development process improvement plan input screen file 24. The contents of the development process improvement plan input screen file 24 can be displayed on the screen of the evaluation apparatus 10.

  The goal achievement additional setting unit 12 reads the gap table 21 described above, and further, for example, is necessary for raising the level of the development process to the goal level based on the additional data for goal achievement inputted by the user or the like. Set the action item, estimated index, estimated cost and estimated man-hour. The additional data includes, for example, “item”, “estimation index”, “estimation”, and the like, but is not limited to this in the present invention. Further, the additional data may be input by the user using an input unit or the like, or may be input from an external device or the like.

  Here, the estimated man-hour set in the target achievement additional setting means 12 is converted into a cost using, for example, data of the project table 22. Further, the goal achievement additional setting means 12 totals the converted costs and stores the results in the cost file 23. The goal achievement addition setting means 12 stores the set setting data in the goal achievement addition input screen file 25. The contents of the goal achievement additional input screen file 25 can be displayed on the screen of the evaluation device 10. Further, the target achievement additional setting means 12 can acquire the cost for authentication for achieving the target level from the achievement required cost table 26 and store the acquired cost in the cost file 23.

  The risk estimate setting means 13 evaluates the risk in the gap table 21 based on the input risk estimate data and the like, and is set by the setting data set by the development process improvement plan setting means 11 or the target achievement additional setting means 12. The probability that the risk can be avoided is set by the set data. Note that the risk estimation data may be input by the user or the like using an input unit or the like, or may be input from an external device or the like. The risk estimate setting unit 13 stores the set setting data in the risk estimate input screen file 27. The contents of the risk estimate input screen file 27 can be displayed on the screen of the evaluation apparatus 10.

  The contents of the development process improvement plan input screen file 24, the goal achievement addition input screen file 25, and the risk estimate input screen file 27 described above are files displayed on the screen of the evaluation apparatus 10, for example. A user or the like can input or change various settings using an input unit or the like while referring to the screen.

  The risk cost conversion means 14 is avoided by achieving the target level, for example, based on the setting data obtained by the risk estimate setting means 13, data obtained from the risk cost conversion table 28 and the project table 22 set in advance by the user or the like. The calculated risk is converted into a cost, and the converted cost is stored in the effect file 29.

  The effect cost acquisition means 15 acquires the effect cost added by achievement of the target level from the achievement effect table 30 preset by the user or the like. In addition, the effect cost acquisition unit 15 stores the acquired effect cost in the effect file 29. Further, the effect cost acquisition means 15 totals the effect costs for each item, and stores them in the target level achievement effect item and the effect cost of the effect file 29. Further, the effect cost acquisition unit 15 stores the result obtained by the risk cost conversion unit 14 and the effect cost acquisition unit 15 in the cost file 23.

  The evaluation result output means 16 selectively refers to, for example, the data of the cost file 23, the effect file 29, the development process improvement plan input screen file 24, the target achievement additional input screen file 25, etc., and the cost effectiveness of the development process improvement plan. Further, the cost required for achieving the target level and the effect thereof are output as an evaluation result 31 to the screen or the outside.

  For example, the evaluation result output unit 16 evaluates the actual cost or the actual effect regardless of the cost of the improvement plan data set by the development process improvement plan setting unit 11 or the like when evaluating the cost effectiveness of the development process improvement. Can also be evaluated. Moreover, the evaluation result output means 16 can also evaluate using the preset evaluation division and the target level preset with respect to the evaluation division irrespective of each practice, for example.

  Here, in the present embodiment, both the process in the development process improvement plan setting unit 11 and the process in the target achievement additional setting unit 12 may be performed, or only one of them may be performed.

  Further, the input of the above-described file or table may be input directly by the user as described above, or may be acquired from an external device. Furthermore, each of the files and tables described above is stored in storage means such as an auxiliary storage device provided in the evaluation apparatus 10, and can be read or written as necessary.

<Development process improvement effect evaluation procedure>
Next, the outline of the evaluation process procedure for the development process improvement effect in this embodiment will be described with reference to a flowchart. FIG. 13 is a flowchart illustrating an example of a procedure for evaluating the development process improvement effect.

Further, by installing the program, the evaluation processing in the present invention can be easily realized by a general-purpose personal computer or the like. Next, a specific example of the above-described evaluation process will be described below.

<S01: Development Process Improvement Plan Setting Procedure>
First, the development process improvement plan setting processing procedure in S01 will be specifically described with reference to a flowchart. FIG. 14 is a flowchart illustrating an example of a development process improvement plan setting process procedure. In the example of FIG. 14, as the development process improvement plan setting process, first, a preset gap table 21 is read, a development process improvement plan input screen is displayed, and stored in a development process improvement plan input screen file (S11). The display format of the development process improvement plan input screen is the same as that of the development process improvement plan input screen file 24 described above, for example.

  Next, in the development process improvement plan setting process, a development process improvement plan, a development process improvement plan cost estimate, etc. input from the user or the outside are read and stored in the development process improvement plan input screen file (S12).

  Next, in the development process improvement plan setting process, the cost amount is calculated and stored in the development process improvement plan input screen file (S13). In this case, the man-hour is converted into a cost by the man-hour unit price in the project table 22. For example, in the case of the expense of practice ID 1.1.3, “0.1 person day × 4 persons + 0.2 person day = 0.6 person day”, “0.6 person day × 1000 thousand yen / 20 days = 30 thousand yen ”.

  Next, the development process improvement plan setting process, for example, for the project process area defined in the overall configuration of FIG. 3 described above, for example, items (predetermined breakdown items) such as personnel increase, tool introduction, training, procedure tailoring, etc. The costs are totaled and stored in the relevant item of the project in the cost file 23 (S14). In this case, the man-hour is converted into a cost by the man-hour unit price in the project table 22.

  Next, the development process improvement plan setting process, for example, for the organizational process area defined in the overall configuration shown in FIG. 3 described above, for example, organization standard procedure manual creation cost, personnel increase, tool introduction, training items (predetermined breakdown items) ) And the like are totalized and stored in the item of the organization of the cost file 23 (S15). In this case, the man-hour is converted into a cost by the man-hour unit price in the project table 22.

<S02: Target achievement additional setting processing procedure>
Next, the target achievement additional setting processing procedure in S02 will be described using a flowchart. FIG. 15 is a flowchart illustrating an example of the target achievement additional setting processing procedure.

  In the example of FIG. 15, as the goal achievement additional setting process, first, the preset gap table 21 is read, displayed on the goal achievement additional input screen, and stored in the goal achievement additional input screen file (S21). Next, in the goal achievement additional setting process, the development process improvement plan is read from the development process improvement plan input screen file 24, displayed on the goal achievement additional input screen, and stored in the goal achievement additional input screen file 25 (S22). Here, the display format of the goal achievement addition input screen is the same as that of the goal achievement addition input screen file 25 described above, for example.

  Next, in the goal achievement additional setting process, the target level achievement required item and the goal level achievement cost estimate input from the user or the outside are read and stored in the goal achievement additional input screen file (S23).

  Next, in the goal achievement addition setting process, the cost amount is calculated and stored in the goal achievement addition input screen file (S24). In this case, the man-hour is converted into a cost by the man-hour unit price in the project table 22. For example, in the case of the expense of practice ID 1.1.3, “3 times × 4 people × 2 hours + 3 person days + 0.2 person days × 4 people + 3 person days = 9.8 person days”, “9.8 Person day × 1000 thousand yen / 20 days = 490 thousand yen ”.

  Next, the goal achievement additional setting process is performed on the project process area defined in the overall configuration shown in FIG. 3 described above, for example, on items (predetermined breakdown items) such as personnel increase, tool introduction, training, procedure tailoring, etc. The costs are totaled and stored in the item of the project of the cost file 23 (S25). In this case, the man-hour is converted into a cost by the man-hour unit price in the project table 22.

  Next, the goal achievement additional setting process is performed for the organizational process area defined in the overall configuration shown in FIG. 3 described above, for example, items such as organizational standard procedure manual creation cost, personnel increase, tool introduction, training, etc. (predetermined breakdown items) ) And the like are aggregated and stored in the item of the organization of the cost file 23 (S26). In this case, the man-hour is converted into a cost by the man-hour unit price in the project table 22.

  Next, the goal achievement additional setting processing reads the data of the achievement required cost table 26, classifies the classification items of the target level achievement cost of the expense file by the cost burden (project, organization), and stores the breakdown and cost. (S27).

<S03: Risk Estimate Setting Processing Procedure>
Next, the risk estimate setting processing procedure in S03 will be described using a flowchart. FIG. 16 is a flowchart illustrating an example of a risk estimate setting process procedure. In the example of FIG. 16, as the risk estimate setting process, first, the preset gap table 21 is read, displayed on the risk estimate input screen, and stored in the risk estimate input screen file 27 (S31). In the risk estimate setting process, setting data such as a development process improvement plan is read from the development process improvement plan input screen file 24, displayed on the risk estimate input screen, and stored in the risk estimate input screen file 27 (S32). The display format of the risk estimate input screen is the same as that of the risk estimate input screen file 27 described above, for example. In the process of S32, for example, setting data may be read from the target achievement additional input screen file 25 and stored in the risk estimate input screen file 27.

  Next, the risk estimation setting process reads the project man-hour and the project period from the risk impact table of the risk cost conversion table 28, the project table 22, and the like, and calculates, for example, the cost person month and the delivery date or number of months, the quality cost, etc. Further, the influence level is displayed as a sub-screen (S33). The display format of the sub screen is the same as the content of the sub screen shown in FIG. 9B described above, for example.

  Next, in the risk estimate setting process, the influence degree, occurrence probability, and risk avoidance probability input from the user or the outside are read and stored in the risk estimate input screen file (S34). Here, the risk avoidance probability is set according to the degree of improvement of the development process with respect to the gap, for example, assuming that the target level of the practice (to eliminate the gap) is 100% risk avoidance probability.

<S04: Risk cost conversion processing procedure>
Next, the risk cost conversion processing procedure in S04 will be described using a flowchart. FIG. 17 is a flowchart illustrating an example of the risk cost conversion processing procedure.

  In the example of FIG. 17, the risk estimate input process screen file 24, the risk cost conversion table 28, and the project table 22 are read as the risk cost conversion process (S41). Next, the risk cost conversion process obtains a risk cost from the degree of influence and the occurrence probability (S42).

  For example, at least one of cost risk, delivery date risk, and quality risk is used as the risk cost, but the present invention is not limited to this. The cost risk can be calculated by, for example, “cost risk = cost ratio of the risk impact degree × occurrence probability × project man-hour × man-hour unit price”. Specifically, for example, when the cost risk has an impact level of 3 and an occurrence probability of 40%, “15% × 40% × 40 person month × 1000 thousand yen = 2400 thousand yen”.

  The delivery date risk can be calculated by, for example, “Delivery date risk = period ratio of the risk impact degree × occurrence probability × sales increase per month × project period”. Specifically, for example, when the delivery date risk has an impact level of 3 and an occurrence probability of 40%, “7.5% × 40% × 4000 thousand yen × 12 months = 1440 thousand yen”.

  Furthermore, the “quality risk” can be calculated, for example, by “quality risk = conversion man-hour ratio of the risk impact degree × occurrence probability × project man-hour × man-hour unit price”. Specifically, for example, when the quality risk has an impact level of 3 and an occurrence probability of 40%, “30% × 40% × 40 person month × 1000 thousand yen = 4800 thousand yen”.

  Here, in the risk cost conversion process, the larger one of the calculated cost risk, delivery date risk and quality risk is set as the risk cost (S43). In the process of S43, for example, an average of cost risk, delivery date risk, and quality risk may be used as the risk cost, or the risk cost may be calculated by other methods.

  Next, the risk cost conversion process calculates an effect cost for the risk cost and stores it in the practice of the effect file (S44). In the process of S44, specifically, the effect cost can be calculated as “development process improvement effect = risk cost × risk avoidance probability”. For example, when the risk cost is 4800 thousand yen and the risk avoidance probability is 20% Is “development process improvement effect = 4800 thousand yen × 20% = 960 thousand yen”. Further, in the present embodiment, it can also be obtained as “target level achievement effect = risk cost × (1−risk avoidance probability)”.

  Next, in the risk cost conversion process, it is determined whether or not all the practices have been calculated (S45). If all the practices have not been calculated (NO in S45), the process returns to S42. Further, when the calculation of all practices is completed (YES in S45), the development process improvement effect and the target level achievement effect, for example, the project process area practice defined in the overall configuration shown in FIG. The data is aggregated for each delivery date / quality and stored in the corresponding item of the effect file 29 (S46).

  In addition, the risk cost conversion process is effective for the development process improvement effect and the target level achievement effect, for example, for the organization process area practice defined in the overall configuration shown in FIG. 3 described above, for example, for each cost, delivery date, and quality. Store in the corresponding item of the file (S47).

<S05: Effective cost acquisition processing procedure>
Next, the effect cost acquisition processing procedure in S05 will be described using a flowchart. FIG. 18 is a flowchart illustrating an example of an effect cost acquisition processing procedure.

  In the example of FIG. 18, as the effect cost acquisition process, items and effect costs are read from the achievement effect table 30 (S51). Next, the effect cost acquisition process sums the effect costs for each item and stores them in the target level achievement effect item and effect cost of the effect file 29 (S52).

<S06: Evaluation Result Output Processing Procedure>
Next, the evaluation result output processing procedure in S06 will be described using a flowchart. FIG. 19 is a flowchart illustrating an example of an evaluation result output processing procedure.

In the example of FIG. 19, as the evaluation result output process, first, the expense file 23 is read, and each expense is totaled (S 61). Specifically, the following processing is performed. In addition, the symbols of the processes A to L shown below correspond to symbols added to items of overall evaluation of evaluation results described later.
A = The cost of the development process improvement plan cost totals the cost of the project.
B = Development process improvement plan cost burden sums the cost of the organization.
C = A + B is calculated.
D = The cost of achieving the target level is the total cost of the project.
E = The cost of achieving the target level is the total cost of the organization.
Calculate F = D + E.

Next, in the evaluation result output process, the project effect of the effect file 29 is read and each effect cost is totaled (S62). Specifically, the following processing is performed.
G = Effective cost of development process improvement effect is tabulated.
H = Aggregate the cost of effect of achieving the target level.

K = G + I is calculated.
Calculate L = H + J.

  Next, the evaluation result output process outputs a development process improvement plan for overall evaluation and achievement of the target level for overall evaluation (S64). Specifically, the evaluation result output process outputs C and K described above as a development process improvement plan for overall evaluation. The evaluation result output process calculates and outputs the return on investment = K / C × 100. Further, the evaluation result output process outputs F and L described above as achievement of the target level of the overall evaluation. In the evaluation result output process, the return on investment = L / F × 100 is calculated and output.

  Next, the evaluation result output process outputs an organization cost effectiveness development process improvement plan and an organization cost effectiveness target level achievement (S65). Specifically, the evaluation result output process outputs B and I described above as the development process improvement plan for the organization cost effectiveness. The evaluation result output process calculates and outputs the return on investment = I / B × 100. Further, the evaluation result output process outputs E and J described above as achievement of the target level of the organizational cost effectiveness. The evaluation result output process calculates and outputs the return on investment = J / E × 100.

  Next, the evaluation result output process outputs a development process improvement plan for project cost effectiveness and achievement of the target level for project cost effectiveness (S66). Specifically, the evaluation result output process outputs A and G described above as a development process improvement plan for project cost effectiveness. In the evaluation result output process, the return on investment = G / A × 100 is calculated and output. Further, the evaluation result output process outputs D and H described above as achievement of the target level of project cost effectiveness. In the evaluation result output process, the return on investment = H / D × 100 is calculated and output.

  Next, the evaluation result output process outputs a development process improvement evaluation breakdown (S67). As an example of the development process improvement evaluation breakdown, for example, the evaluation result output processing reads and outputs the cost burden, breakdown, and expense of the classification of the development process improvement plan cost in the cost file 23. Also, the evaluation result output process reads and outputs the project effect development process improvement effect item and effect cost in the effect file 29. The evaluation result output process reads and outputs the item of the effect of improving the development process of the organization effect and the effect cost in the effect file 29. In the evaluation result output process, the practice ID, practice name, development process improvement plan, and cost are read from the development process improvement input screen file 24 and output. In the evaluation result output process, the development process improvement effect is read from the practice unit effect of the effect file 29 and output.

  Next, the evaluation result output process outputs a target level achievement evaluation breakdown (S68). As an example of the target level achievement evaluation breakdown, for example, the evaluation result output processing reads and outputs the cost burden, breakdown, and cost of the classification of the target level achievement cost in the cost file 23. Also, the evaluation result output process reads and outputs the item of effect level achievement effect and effect cost of the project effect in the effect file 29. Further, the evaluation result output process reads and outputs the item of effect of achieving the target level of the organizational effect and the effect cost in the effect file 29. The evaluation result output process reads and outputs the practice ID, practice name, target level achievement required item, and cost from the target level achievement additional input screen file 25. The evaluation result output process reads and outputs the target level achievement effect from the practice unit effect of the effect file 29. Note that the above-described evaluation process is executed by control by a CPU or the like, for example.

<About evaluation result 31>
Next, an example of the evaluation result 31 output from the evaluation result output unit 16 in the present embodiment will be described with reference to the drawings. FIGS. 20 to 22 are diagrams illustrating an example of the evaluation result in the present embodiment (part 1). ~ 3).

  In the example of FIG. 20, evaluation results of “overall evaluation”, “organization cost effectiveness”, and “project cost effectiveness” are displayed. Note that A to L shown in FIG. 20 output the results of the mathematical expressions of the above-described processes A to L. That is, the content output in FIG. 20 is mainly the content obtained by the processing of S66 of FIG. 19 described above as the overall evaluation format shown in FIG. In this embodiment, since there may be a plurality of organizations and projects for one overall evaluation, the example shown in FIG. 20 is not limited to a single organization or project, but for a plurality of organizations or a plurality of projects. The evaluation result can be output every time.

  Thereby, in this embodiment, evaluation by cost effectiveness can be performed for every evaluation, every organization, and every project, and the evaluation accuracy of the development process improvement effect can be improved.

  FIG. 21 shows a breakdown of development process improvement evaluation. Here, the content output in FIG. 21 is mainly the content obtained in the process of S67 of FIG. 19 described above as the format of the development process improvement evaluation breakdown. Further, FIG. 22 shows a breakdown of the target level achievement evaluation. Here, the content output in FIG. 22 is mainly the content obtained by the processing of S68 in FIG. 19 described above as the format of the target level achievement evaluation breakdown. The layout of the evaluation results shown in FIGS. 20 to 22 is not limited to this, and can be arbitrarily changed by setting by the user or the like.

  As described above, in the present embodiment, not only the magnitude of risk but also the cost-effectiveness of development process improvement can be obtained quantitatively as cost. In the present embodiment, for cost conversion, for example, evaluation can be performed in correspondence with both a case where a target level authenticated from outside such as acquisition of certification is achieved and a case of other development process improvement. In the present embodiment, in the cost-effectiveness calculation, the generated cost and the effective cost are calculated. Effective cost is calculated by converting the risk avoidance due to the improvement of development process into cost, and calculating the cost effect by external certification such as acquisition of certification.

  Further, according to the present embodiment, it is possible to calculate by dividing the cost by the organizational department cost and the project cost. When there are a plurality of organizations or projects, the evaluation results can be output in units of the organizations or projects.

  That is, according to the present embodiment, cost, quality, and delivery date risk avoidance can be evaluated in terms of cost. In the case of certification acquisition, the effect of achieving the target level can be added and evaluated.

  The target level in the above-described embodiment indicates, for example, an item (hereinafter referred to as practice) that details the standard development process required in CMMI level 3, and the achievement level of the practice. However, in the present invention, the evaluation method described above can be applied based on other preset criteria (for example, international standards) without using CMMI as shown in the above-described embodiments.

  For example, in the example described above, the development process is defined as a “process area”, applied to CMMI, a “goal” is set for each process area, and a “practice” that further refines the “goal” is used. For example, by applying to ISO 12207, an “activity” may be set for each process, and a “task” that further refines the “activity” may be used to evaluate the development process improvement effect.

  Further, when applying this embodiment, for example, in the case of “Information technology-Process assessment” defined in ISO 15504 as an example of a preset evaluation category or a target level of the preset evaluation category, In addition, Base Practice (basic practice) can be used as the preset evaluation category, and Capability Level (capability level) can be used as the target level of the preset evaluation category.

  When this embodiment is applied, for example, in the case of “Software engineering- Lifecycle profiles for Very Small Entities (VSEs)” defined in ISO_IEC — 29110, Task (task) is set as a preset evaluation category. It is possible to use Level as a target level of the evaluation category set in advance.

  Furthermore, when this embodiment is applied, for example, in the case of “Functional safety of electrical / electrical / programmable electronic safety-related systems” defined in IEC61508, a measurement method (measure) is used as a pre-set evaluation category. The Safety Integrity Level (safety level) can be used as the target level of the evaluation category set in advance. Note that the criteria applicable to the present embodiment are not limited to this.

  As described above, according to the present invention, the evaluation accuracy of the development process improvement effect can be improved. Specifically, the present invention quantifies and presents the cost effectiveness of the development process improvement for the evaluation of the development process improvement effect due to the development risk, etc., thereby explaining the effect of the development process improvement plan and the development process improvement plan. This makes it possible to plan and implement optimal development process improvements.

  In addition, according to the present invention, it is possible to evaluate a cost-effectiveness further required to achieve a target level, thereby making it possible to review an appropriate plan and to make a medium- to long-term plan. In addition, by evaluating the effect of risk, for example, it is possible to perform a precise evaluation corresponding to the degree of improvement, rather than improving a certain practice.

  In the present invention, for example, at the time of budget preparation before development, etc., it is possible to evaluate the development process improvement effect by inputting actual values and predicted values so far, and during execution of the development process, for example, a predetermined value may be used. The actual value or the predicted value at that time may be input for each period of time, and the development process improvement effect at that time may be evaluated.

  Further, the present invention can be widely applied not only to the field of, for example, power electronics products but also to product development process technologies for other developed products in general.

  The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to such specific embodiments, and various modifications, within the scope of the gist of the present invention described in the claims, It can be changed.
