摘要
An output item finally determined by computer software to be developed is extracted, and the output data is defined by using a data generation formula using intermediate data items. The definition processing of defining all the intermediate data items by using different data generation formulae is repeated until generation of a data item is due to input data. The definition including the thus generated data items and data generation formula execution conditions is used as a requirement definition. The thus-made requirement definition and the processing order of data items are automatically found out. Alternatively data is automatically rearranged. As a result, a program is automatically created. Such a method is applied to development of software. When requirement words are changed, words that are different from the requirement words before and after the change and define the methods of generating the requirement words are extracted and presented. Further, out of the different words, words the generation methods of which are defined by the requirement words are also extracted and presented. The necessity of the word change is examined. If the change is necessary, the change processing is continued; if not, the change processing of the requirement words is ended.
