THE HELICAL APPROACH TO SOFTWARE-DESIGN

This paper is used to outline a relatively recent approach to the development of software products. Practical experience of employing the traditional waterfall lifecycle model, the Spiral Model and concurrent engineering approaches in both small and large (pan-European) software projects provide the foundation on which to present, discuss and propose a new lifecycle model; the Helical LifeCycle Approach. The authors of the paper distinguish between prototypes, and model and postulate the need for the formalization of a new software engineering job role which is focused around the Helical Project LifeCycle.
