Abstract This paper is divided into two parts. The first contains a survey of various system development lifecycle models, including the Waterfall, Spiral, and Evolutionary Models. The second part introduces a conceptual framework for a new approach to complex, large‐scale system developments based upon a customer focus throughout the system development lifecycle. This customer‐focused approach utilizes automated Concept of Operations (CONOPS) and group dynamics techniques to allow greater understanding of end‐user ‘actual’ needs by system designers via more productive interactions. This approach is based on the development and use of detailed user objectives and critical success factors prior to and separate from their mapping into basic and derived system requirements. It provides a means for capturing previously obscure requirements within the user environment and mindset.
