CHANGE-POINTS - A PROPOSAL FOR SOFTWARE PRODUCTIVITY-MEASUREMENT

This article describes a productivity measurement approach based on a common output for design, implementation, and testing. It relies on the traditional definition of productivity: Output divided by Input = Productivity. It presents the concept of a unit of work - an abstract work item - which reflects that, to manage a development project, we must make logical subdivisions of the work effort. The notion of CHANGE-POINTs is derived from these subdivisions. Because we need to view productivity within the context of effectiveness, the article introduces the productivity, interference, and effectiveness matrix for that purpose.
