This paper presents an overview of the process theory developed in the context of the ESPRIT project NATURE.1 This theory proposes means for modelling and engineering the requirements engineering (RE) process. The key element of this theory is a situation-and decision-based process meta-model independent of any RE methodology. The process meta-model acts as a shell for defining process models by instantiation. An enactment mechanism implemented in a tool environment has been defined. It allows execution of process models and provides effective guidance to the requirements engineer. Construction of process models is also supported based on generic method knowledge chunks. The formalization of our approach is based on a free algebra.
