2208 Approach to deriving the grounds of reasonable estimation of the project size from accumulated data

Abstract

In order to achieve the business plan and to plan the project properly, it is important subject making progress in accurate estimation. The systematical evaluation methodology, certainty of the input data which is basis of estimation, taking risks into consideration and 'definition of the grounds of evaluation value' are key factors for improvement of evaluation accuracy. We have tried to establish evaluation model which systematically integrates these factors In this article we propose our activities to derive productivity metrics from the actual productivity data of the similar projects which we have completed, in order to achieve 'definition of the grounds of evaluation value' of the estimation model
