- 1 - Models of Systems , Work Products , and Notations 1 Wolfgang

Software development means the development of a wide range of work products covering different views on a system. These views are generally represented using different notations. In this paper we propose a model for the static part of a software development process that enables an integrated foundation of work products on the basis of a system model, as well as a flexible foundation of notations on the basis of work products. We differentiate between models of notations, work products, and systems and show their relationships. An example covering a system model for object-based systems together with different work product types and their representations by alternative notations illustrates our approach.
