Design systems engineering of software products: implementation of a software estimation model

In this paper, we present the implementation of a software estimation model to evaluate effort, schedule and cost of software development during all the phases of a project. An approach based on COCOMO II model is used, and we propose an adaptation to a particular context of an organization. Both human and cultural aspects of the company are considered in order to mitigate the problem of acceptability. Our model is based on the work of Dr. Allan Albrecht on Function Points (FP) and Dr. Barry Boehm on COCOMO II model
