It is stored.

Again with reference to FIG. 1, each component of the product development process evaluation system 1 according to the embodiment will be described in detail.

The product development information input means 10 has a function of inputting an index for evaluating the product development process. Product development process evaluation system 1 according to the present embodiment
The indicators used for evaluation in are classified into a business performance evaluation index, a development performance evaluation index, a process state evaluation index, and a process quality evaluation index. “Business outcomes evaluation index” is an index that quantifies the business outcomes obtained when a certain product is developed and put on the market. For example, product sales, profit, product market share, product cost, etc. There is an indicator of. What is a "development result evaluation index"?
It is an index of the results of product development, and includes, for example, development productivity such as man-hours, time, and cost of development, and product level such as function, cost, and reliability. The “process state evaluation index” is an index related to the entire development process. The “process quality evaluation index” is an index related to an opportunity to improve a detailed item of a process, and includes an engineering evaluation index, a development management evaluation index, and a collaboration evaluation index. Although the product development information is classified into four here, the process state evaluation index and the process quality evaluation index may be a single process evaluation index.
Here, a specific method of inputting product development information will be described. First, the product development information input screen as shown in FIG. 3 is displayed, and the business type and type of the product are input. This is because a tendency of a specific index value may be obtained for each product, so that they can be classified so that more accurate evaluation can be performed. Next, an evaluation menu as shown in FIG. 4 is displayed to input an evaluation index. FIG. 4 shows an example of the input screen of the process quality evaluation index. The user can input the evaluation index by answering the displayed questionnaire.

The index value DB 11 stores each index value input by the product development information input means 10.
FIG. 5 is a diagram showing an example of index values stored in the index value DB 11. The value input by the evaluation menu shown in FIG. 4 is converted into an index value based on a predetermined formula. In the present embodiment, the index value is calculated based on the input values of “functionality” and “penetration degree”. As can be seen from the fact that a plurality of users input product development information using the same questionnaire as shown in the input screen (see FIG. 3) and accumulate the index value in the index value DB 11,
The index values of a plurality of products are stored for each index. Thereby, if the index value DB 11 is referred to,
The reference value of each index can be calculated. It is also possible to calculate the reference value for each type of industry and product.

The index correlation DB 12 is a database that stores the respective correlations of the business performance evaluation index, the development performance evaluation index, the process state evaluation index, and the process quality evaluation index. FIG. 6 is a diagram showing the relationship of each index. As can be seen from FIG. 6, there is a relationship between the business result and the development result that the business result is the result of the development result and the development result is the factor of the business result. That is, the business performance evaluation index can be explained using the development performance evaluation index as an explanatory variable. There is a similar relationship between the development performance evaluation index and the process state evaluation index and between the process state evaluation index and the process quality evaluation index. FIG. 7 is a diagram schematically showing the index correlation DB 12. As shown in FIG. 7, the index correlation DB
Reference numeral 12 stores the correlation between adjacent indexes in FIG. 6 as a table of correlation values. FIG. 8 shows a specific example of the correlation value table. FIG. 8 shows an example of the correlation between the process state evaluation index and the process quality evaluation index. The items of the process state evaluation index are listed vertically and the items of the process quality evaluation index are listed horizontally. The numerical value written at the position where the vertical item and the horizontal item intersect is the correlation value,
Indicates the strength of correlation between vertical items and horizontal items. Correlation value is 1
It is shown that the closer to, the stronger the correlation, and the closer to 0, the weaker the correlation. For example, "front loading degree"
The correlation value between the “advanced cost target achievement level” and the “cost / manufacturability evaluation” is “0.94”, and it can be seen that the correlation is strongest in FIG. In FIG. 8, numerical values are omitted for items having a small correlation value.

The correlation calculating means 13 has an index value DB 11
It has a function of calculating the correlation between the indexes as a correlation value by statistically analyzing the index value stored in (1), and stores the information of the calculated correlation value in the index correlation DB 12.

The index value input means 14 has a function of inputting each index of the product to be evaluated.

The deviation degree calculating means 15 has a function of calculating the deviation degree from the reference value for the inputted index value.
Here, the “reference value” of the index may be an average value of the index values stored in the index value DB 11 or a value in which the index values of many products are concentrated with respect to the index. good. In the present embodiment, the deviation degree from the reference value is calculated by the deviation value. A specific method of calculating the deviation degree will be described with reference to FIG. As shown in FIG. 9, when an index value is input for a certain index, the deviation value of the index value is calculated based on the index value stored in the index value DB 11. Then, the deviation degree of the index is calculated based on the calculated deviation value. The divergence is calculated based on the formula divergence = (100−deviation value) / 10. As described above, in the present embodiment, the formula is used such that the deviation degree of the index increases as the deviation value decreases, but the calculation expression of the deviation degree is not necessarily limited to this, and other calculation expressions may be used. It is possible.

The divergence index extracting means 16 has a function of extracting, from the index values input by the index value input means 14, an index having a large divergence degree as a divergence index. To determine whether or not the degree of deviation is large, the user inputs a threshold value in advance and each index having a degree of deviation larger than the threshold value is extracted. For example, when the threshold value input by the user is 5.0, "basic performance evaluation" and "mountability evaluation" among the evaluation items shown in FIG.
The item of "quality / reliability evaluation" will be extracted as a deviation index.

To extract. Specifically, first, the importance of each deviation index B1 is calculated using the formula of importance = (Σ (deviation degree of deviation index A × correlation value)) × deviation degree of deviation index B1. Here, the direction in which the value calculated by (deviation degree of deviation index A × correlation value) is added is the value of each (deviation degree × correlation value) of the deviation index A for one deviation index B1. FIG. 8 is an example of the correlation between the process state evaluation index and the process quality evaluation index, but since the configuration of the correlation table is the same, a more specific description of this formula using FIG.

Then, the importance of the "basic performance evaluation" is calculated by multiplying the result by the deviation degree of the "basic performance evaluation". In this way, after calculating the importance of each development result evaluation index, a predetermined number of development result evaluation indices are extracted in descending order of importance, and are set as the important index B2. Next, the correlation table (inside table) showing the correlation between the development performance evaluation index and the process state evaluation index is referred to. The important index B2 extracted earlier and the deviation index C1 extracted by the deviation index extraction means 16 out of the process state evaluation indexes are used. Important index B2
And the process state evaluation index deviation index C1 The process state evaluation index important index C2 is extracted by the same method as described above based on the deviation degree and the correlation value. Further, the important index D2 of the process quality evaluation index is extracted based on the extracted importance degree of the important index C2, the deviation degree of the process quality evaluation index D1 and the correlation value.
