Description

  The present invention relates to a development support apparatus that supports product development work. More specifically, the present invention relates to a development support apparatus that extracts problems predicted to occur during development from problems of products developed in the past. The present invention relates to a support method and a program.

  There are two main types of product development: new product development, which develops new products that have not existed before, and existing improved product development, which is developed by adding or improving functions based on past products. Can be separated. There are few product developments that are carried out in the newly developed type, and most product developments are existing improved type product developments.

  In product development, quality control is an important issue, and quality control personnel are expected to encounter the product specifications of newly developed products in order to suppress the occurrence of quality problems in product development. The problems are extracted with reference to the problems that occurred in the past product development, and documented. The collected documents are distributed to the designers to be alerted or used as a checklist for review. This work should be done at an early stage of product development, especially immediately after specification.

  As a first conventional technique for supporting development, there is a development support system that presents knowledge information, that is, information technically related to a task in charge, to a development designer. This development support system associates the components that make up development products, including development products developed in the past, that is, combinations of models, units, and parts, with keywords that indicate technical themes, and further associates keywords with knowledge information. And register in advance. When the person in charge requests presentation of knowledge information, first, the keyword corresponding to the component in charge of the person in charge is read from the keywords registered in association with each component constituting the development product. Next, based on the read keyword, knowledge information related to the component in charge of the person in charge is extracted and presented from the knowledge information registered in association with the keyword. Thus, by using keywords, knowledge information related to components different from the components in charge of the person in charge can be presented, so that the person in charge can obtain a wide range of information (for example, patents) Reference 1).

  As a second conventional technique for supporting development, there is a product information comparison system that compares a plurality of pieces of product information having standard information indicating the characteristics of the product and displays the differences visually. This product information comparison system compares the product information of the standard product and the product information of other products for each characteristic, and the differences, for example, newly added characteristics, previously deleted characteristics, Alternatively, a characteristic of a level different from the level is displayed so as to be visually recognizable, for example, shaded or color-coded. Differences in the characteristics that are visually recognizable can be reflected in the specifications of the developed product, preventing the occurrence of quality problems and improving the product development efficiency (for example, patents) Reference 2).

  The first conventional technique searches and presents knowledge information, that is, information technically related to a task in charge, based on a keyword corresponding to a component that the person in charge is in charge of. However, since the person in charge is not determined at the initial stage of development, there is a problem that the component in charge of the person in charge cannot be specified and the development support system cannot be used well. Furthermore, the knowledge information corresponding to the component that the person in charge is responsible for is extracted from the knowledge information of all past development products, so the amount of knowledge information that the person in charge must check is enormous. It takes a lot of time and effort to confirm all the knowledge information obtained. Furthermore, the obtained knowledge information includes knowledge information that has been referred to in the past, and time is wasted in order to exclude the referenced knowledge information.

  In the second conventional technique, product information of a reference product and product information of other products are compared for each characteristic, and the difference is displayed in a visually recognizable manner. However, regarding the difference in characteristics, investigating the related quality problem or inquiring the related person has a problem that the person in charge needs to perform separately separately, which is inefficient. Furthermore, investigations and inquiries often depend on individual know-how, and there is a possibility of leakage or omission.

  Standard product attribute information list, new product attribute information list, difference list, general attribute difference list, general attribute difference related part name list, used part name difference list, related part name list, and related problems A table such as a list is created when the control device 12 executes the program of the specification difference extraction processing unit 113, the problem extraction processing unit 114, and the problem display processing unit 115 to process the processing procedure shown in FIG. The table is temporarily used and is stored in the memory 13.

  In this way, when extracting the problems, the product specifications of the new product and the product specifications of the reference product are compared, and the product specifications of the new product that differ from the product specifications of the reference product are extracted and extracted. Since the problems related to the difference specification are extracted, only the problems that should be particularly noted this time from which problems that have been referred to in the past have been removed can be obtained. Therefore, it is possible to reduce the work time for the confirmation work of the extracted problems, and it is possible to improve the work efficiency for suppressing the occurrence of quality problems. In addition, problems related to the product specifications of the new product can be extracted without depending on the component of the product for which the development designer is in charge, so that the problems can be extracted at the initial stage of product development.

  In other words, once the product specifications of a new product are determined, the quality control person in charge of the new product does not include the same product specifications as the product specifications of the past reference product that is the basis of the new product. Based on the specifications, it is possible to automatically extract a problem that may newly occur from problems that have occurred in the past. Further, the extracted problems can be collected and distributed to a person in charge of development design to call attention, or used as a check list at the time of review, thereby suppressing the occurrence of quality problems.

  That is, new product that is different from the product specification information representing the product specification of the reference product, that is, product specification information of the attention product is extracted as difference specification information, and problem information related to the extracted difference specification information is further extracted. When the product specification information is determined, the problem information from which the problem information related to the product specification information of the reference product is removed can be extracted. Therefore, at the initial stage of product development, problems that may newly occur can be extracted based on the product specifications of the new product, and the occurrence of quality problems can be suppressed.

  Further, the part is stored in association with a product specification, for example, a combination of attribute name and attribute value, and the problem is stored in association with the part, and the product specification indicated by the extracted difference specification, for example, attribute name and attribute is stored. Since parts related to the combination of values are extracted, and problems related to the extracted parts are extracted, problems specific to the new product can be extracted even from parts not used in the standard product. It can be effectively used to predict the occurrence of quality problems.

  That is, the part identification information is associated with the product specification information representing the product specification related to the part of the part identification information, and the part name of the part related to the problem information, that is, the part identification information is stored in association with the problem information. Since the problem information related to the part identification information is extracted from the part identification information related to the product specification information included in the difference specification information, the problem information related to the parts not used in the reference product is extracted. be able to. Therefore, problem information related to the product specification unique to the product of interest can be extracted from a wide range, which is effective in preventing the occurrence of quality problems.

  Furthermore, the part names of the parts that make up the product are included in the product specifications, and problems related to the parts with the part names included in the product specifications indicated by the difference specifications are extracted. Related problems can be extracted.

  That is, the product specification information indicating the product specification includes the part names of the parts constituting the product of the product specification, that is, the part identification information, and the problem information related to the part of the part identification information included in the difference specification information is extracted. The problem information related to the parts used in the reference product can be excluded. Therefore, it is possible to extract problem information related to a part newly used in the product of interest.
