A Guide to Development

The guide proposes a simple model consisting of a set of divergent and convergent activities with reviews before continuing to the next phase of development. The use of the model is designed to improve the productivity of those associated with development. None of the individual tasks is novel; the key to increasing the chances of success lies in the commitment and common understanding which can be generated. Examples are given relating to the chemical industry and to software engineering. Keywords: Development methodology, chemical processes, software engineering.
