Goal Driven Enterprise Modelling: Bridging Pragmatic and Semantic Descriptions of Information Systems

Concepts, relationships and rules in the specification of requirements of information systems exist for some reason. They express the needs and rationale of requirements at pragmatic level. On the other hand, goals justify and explain the presence of requirement components. The problem here is to bridge the gap between the description of initial requirements and the precise specification of functional requirements of information systems. Explanation of goals in terms of static and dynamic constraints is of interest, because it allows the interpretation of goals as a driving force in the process of requirements modelling. The objective of this paper is to describe some pragmatic dependencies using several types of semantic relationships in the context of goal driven information system modelling. The purpose for introducing the interaction between different classes of semantic and pragmatic dependencies is that developed specification of information system could be unambiguously interpreted among domain experts, and that it could be used for assessment of the quality of requirements.
