Abstract: A software development production management system having a processor, which is enhanced in reliability by reducing a different between an evaluation of an actual development and a formed plan. A management database holds both development process component data necessary to model a development process of software and estimation parameter data used to estimate a development plan of the software. The software development production management device compares and evaluates, upon completion of the software development, an actually performed development process and the previously created software development plan, and makes a correction to the estimation parameter data as needed to feed details of the actually conducted software development back to the next development plan.

Abstract: Provided is a software development production management system, which is enhanced in reliability by reducing a difference between an evaluation of an actual development and a formed plan. A management database (3) holds both development process component data necessary to model a development process of software and estimation parameter data used to estimate a development plan of the software. A software development production management device (1) defines a software development process to be managed by consulting the development process component data held in the management database (3), and uses the estimation parameter data to create a software development plan from the defined software development process.
