<P>PROBLEM TO BE SOLVED: To support decision of granularity of a component to be applied to a system that is a development object. <P>SOLUTION: An information processor supports design of the system as the development object. The processor refers to information for the development object system, information for an existing system to be entirely or partially replaced by the development object system, and information showing restriction of granularity that is a unit showing the size of a component applied to the development object system, thereby deriving a granularity application plan that is a plan for the granularity of a component applicable to the development object system. The processor further refers to the derived granularity application plan, the information for the development object system, the information for the existing system, and information showing relationship between cost that is an expense associated with design, development and maintenance of the development object system and various evaluation items, thereby calculating the cost associated with design, development and maintenance of the development object system in application of the granularity application plan to the development object system. <P>COPYRIGHT: (C)2011,JPO&INPIT |
