A Compositional Knowledge Level Process Model of Requirements Engineering

Abstract

In current literature few detailed process models for Requirements Engineering are presented: usually high-level activities are distinguished, without a more precise specification of each activity. In this paper the process of Requirements Engineering has been analyzed using knowledge-level modelling techniques, resulting in a well-specified compositional process model for the Requirements Engineering task. This process model is considered to be a generic process model: it can be refined (by instantiation or specialisation) into a process model for a specific kind of Requirements Engineering process.

Requirements engineering methodologies for COTS systems

“…Elicitation -requirements are discovered 2. Analysis and negotiation -"conflicts, ambiguities and inconsistencies" [9] are found and stakeholder agreement is sought. 3.…”

“…4. Documentation -requirements are noted and maintained [9]. These are the "must haves" that a requirements engineering methodology needs to have.…”

Knowledge Based System for Business Software

“…Knowledge level process model of requirement engineering is a set of abstractions that represents requirement elicitation, manipulation and maintenance processes. Thus knowledge-level process is important for its decomposition based on separation of concerns and realization of applicable characterization [1]. Difficulties associated with the engineering of complex systems have manifested themselves in a crisis of software productivity.…”
