Towards a Rigorous Process Modeling With Spem

Abstract

Modeling software process is a good way to improve development and thus quality of resulting applications. The OMG proposes the SPEM metamodel to describe software processes. Its concepts are described through class diagrams. Unfortunately, it lacks a formal description of its semantics that makes it hard to use. So, we propose a specialization of SPEM that clarifies it and we use OCL to formally express constraints on it.
