Patent ID: 7849442

Claim:
An application requirement design support system for supporting design of a new case inputted thereto, by reusing existing contents beforehand stored, comprising: processors; receiving means for receiving information regarding the new case; common systemic hierarchical framework extracting means for extracting common systemic hierarchical frameworks associated with at least one systemic hierarchical work function contained in the information regarding the new case from a common systemic hierarchical framework database having stored common systemic hierarchical frameworks corresponding to candidate systemic hierarchical work functions, where each common systemic hierarchical framework lists a plurality of interrelated work functions at a plurality of different gradation levels of detail, the at least one systemic hierarchical work function being for utilization in a systemic hierarchical system application, the extracting effected by using the information regarding the new case as a searching key, the common systemic hierarchical frameworks having correspondence relationships to design information of all the existing contents; existing contents extracting means for extracting existing contents corresponding to the information regarding the new case from an application product table and an application product function table by using the information regarding the new case, the existing contents including an existing application product and an object achieving method; common systemic hierarchical framework assigning means for assigning the existing application product and the object achieving method which are the existing contents thus extracted to the common systemic hierarchical frameworks thus extracted and creating an assignment table for each common systemic hierarchical framework; application requirement extracting means for extracting, according to the assignment table thus created, application requirements associated with the new case received by the receiving means; and wherein the assignment table created for each common systemic hierarchical framework is associated with, for an associated common systemic hierarchical framework, object achieving methods and application products of systemic hierarchical work functions associated with the associated common systemic hierarchical framework.
