Software process models describe the engineering of a product, e.g. the software that has to be produced. Directions in Software Process Research . Advances in Computers, Vol. 41, Academic Press. The variety of existing process support systems, for example process sensitive software engineering environments or workflow management systems, corresponds to the variety of process types.
Planning provides parameters which adapt process models to different contexts.
Plan deviations are not considered. No support for modifying the project s state is provided. Directions in software process research . In Marvin V. Zelkowitz, editor, Advances in Computers, vol. Academic Press, 1995.
