SOFTWARE MODIFICATION ESTIMATE METHOD AND SOFTWARE MODIFICATION ESTIMATE SYSTEM

摘要

The subject matter is directed to a software modification estimate method and a software modification estimate system that make it possible to assemble a modification development plan prior to modification work on existing software. The software modification estimate method and the software modification estimate system are provided with an input and output means (1) that inputs and outputs information on the modification of existing software, a modification estimate calculation means (2) that analyzes a modification requirement based on the information received from the input and output means and numerically calculates the fluctuation of productivity in the modification, and a database (3) that stores data necessary for the analysis and that holds the analyzed result. Thus, it is possible to estimate total steps required for the modification of the software at a preparation stage.
