Three Numbers to Measure Project Performance
We present a method which produces at any time during the execution of a big software
development project a reliable prediction of the total duration and of the total cost to expect
at project completion. The basic idea presented in our paper is to correlate cumulative cost consumed to current
completion reached, and to learn out of this about the future of the project. Prerequisites
are a cost consumption plan and a deliverables completion plan. The approach is
presented both theoretically and on hand of a real life case. Special attention is paid to
project management techniques related to the method.
