John Krogstie (born 23 May 1967) is a Norwegian computer scientist, professor in information systems at the Norwegian University of Science and Technology (NTNU) in Trondheim, Norway, and an expert in the field of enterprise modelling.

Biography[edit]

John Krogstie received a MSc in 1991 and a PhD in 1995 both in information systems from the Norwegian University of Science and Technology.[1] From 1991 to 2000 he was employed as a manager in Accenture. In 2000-2005 he was a senior researcher in SINTEF. He is a professor in information systems at NTNU in Trondheim, Norway.[2]

John Krogstie is the Norwegian representative for IFIP TC8 and was Chair (2010–2015) of IFIP WG 8.1 on information systems design and evaluation.

Work[edit]

Krogstie's research interests include information systems, conceptual modeling, mobile information systems, eGovernment and enterprise modelling.

The SEQUAL framework[edit]

The SEQUAL framework is a reference model for evaluating the quality of models, the semiotic quality framework (SEQUAL) developed by John Krogstie.[3] The SEQUAL framework is grounded in semiotics, particularly the semiotic theory of Charles W. Morris. It builds on semiotic theory and defines several quality aspects based on relationships between a model, a body of knowledge, a domain, a modeling language, and the activities of learning, taking action, and modeling.[4] Its usefulness was confirmed in an 2002 experiment.[5]

The basic idea behind the SEQUAL framework is, that conceptual models can be considered as sets of statements in a language, and therefore can be evaluated in semiotic/linguistic terms. A first semiotic framework for evaluating conceptual models was originally proposed by Lindland et al. in the 1994 article "Understanding quality in conceptual modeling".[6] In its initial version, it considered three quality levels:

  • syntactic,
  • semantic, and
  • pragmatic quality

The framework was later extended, and called the SEQUAL framework by Krogstie et al. in the 1995 article "Defining quality aspects for conceptual models".[7] In the 2002 article "Quality of interactive models"[8] Krogstie & Jørgensen extended the initial framework adding more levels of Stamper’s semiotic ladder.[9]
