What is a good business process model and how do you get value from it? We have for many years worked with SEQUAL, a general framework for understanding the quality of models and modelling languages, which covers all main aspects relative to quality of models. The framework has been widely cited since the first version was presented in the nineties, and the tutorial will focus on the most recent version of the framework (2016), specialised for quality of business process models, with a focus on how to achieve value through long-term usage of business process models in organizations.

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 evolves as modelling takes
The goal of the tutorial is to discuss issues of achieving value from business process models through addressing the appropriate quality of models. The second aspect is based on how the SEQUAL framework on quality of models and modeling languages can be used in practice to assess and evaluate a business process model. Based on the tutorial and accompanying material, the participants should be able to use the framework in their own work. The tutorial covers both the theoretical framework and in-depth case studies where the framework has been utilized

Publications looking on getting value from and quality of business process modelling in general are quite common in BPM and other BPM-oriented events. SEQUAL in itself has been around and used for several years. This tutorial will be based on material that adapts and extend and exemplify the use of the framework for business process models that is part of a forthcoming book (Krogstie 2016).

The teaching will be a combination of presentation of overall principles, exemplifying the overall principles with examples, application of the framework in industrial cases, and small interactions with the audience including Kahoot! quizzes
