Abstract: Enterprise modelling frameworks are effective tools to communicate organisation|s structure, processes, and information systems. However, an increasingly interconnected, dynamic, and uncertain world is pressing to regard organisations and information systems as complex evolving systems. This paper: 1) argues the importance of using complexity principles in analysing, modelling and (re)designing organisations and its information systems; 2) discusses the conceptual implications and limitations of current enterprise modelling frameworks regarding complexity principles; 3) proposes an extension to overcome such limitations; 4) illustrates some benefits of this extension with a case study.

Keywords: enterprise architecture; complex systems; complexity principles; organisational design; modelling; information systems; enterprise modelling; organisational structure.
