Abstract

Earned value management (EVM) has long been used by organizations to plan, monitor, and control the development and evolution of custom developed systems. EVM was developed for managing such projects, and assumes a waterfall development model. COTS-based systems (CBS), on the other hand, are formed and evolved through the selection and composition of pre-existing, off-the-shelf packages or components with potentially some number of custom components. Experience indicates that a spiral or iterative development process is a key to success with CBS. While EVM has been applied to CBS projects, the results have not been uniformly satisfying. This paper explores the fundamental challenges in using EVM with CBS, and proposes adaptations to some of the principals of EVM to render it more suitable for CBS development.
