We have for many years worked with SEQUAL, a framework for understanding the quality of models and modelling languages, which covers all main aspects relative to quality of models. SEQUAL has three unique properties compared to other frameworks for quality of models: It distinguishes between quality characteristics (goals) and means to potentially achieve these goals by separating what you are trying to achieve from how to achieve it ; It is closely linked to linguistic and semiotic concepts. In particular, the core of the framework including the discussion on syntax, semantics, and pragmatics is parallel to the use of these terms in the semiotic theory of Morris. A term such a ‘quality’ is applicable on all semiotic levels. We include physical, empirical, syntactical, semantical, pragmatic, social, and deontic quality in the work on SEQUAL ; It is based on a constructivistic world-view, recognizing that models are usually created as part of a dialogue between those involved in modelling, whose knowledge of the modelling domain changes as modelling takes place. We will in the talk present the general SEQUAL framework and how it can be specialized for investigating the quality of enterprise model. Starting from a generic framework means that we can reuse a number of aspects being of general relevance for modelling, and thus better ground the proposals, both for quality of enterprise models, modelling languages, and accompanying approaches, methods and tools to achieve and keep models of high quality.
