His/Her biography

After I obtained my Ph.D. in theoretical physics at the ETH Lausanne, I worked as a researcher in statistical physics at Princeton University, in CNRS at the Ecole Polytechnique and at the ETH Zürich. Ten years ago, I shifted to enterprise computing, initially initially specializing as a software architect in the Java Enterprise technologies. Meanwhile I specialized in UML for designing and specifying business applications. I helped a number of companies (banking and industry) in the definition of SOA architectures using UML as a core methodology. More recently, at Alcyonix, I became interested in understanding what makes the complexity of an information system and understand how it can be connected to various ideas of value. This work has been published in a book "Managing Complexity of Information Systems" published by Wiley.

Pitch of his/her session

The topic I would like to address is the complexity of information Systems (IS) both from a conceptual and an applied perspective. The concepts used in the analysis are drawn from information theory, industrial design and software engineering. The analysis capitalizes on experiences gathered during various contracting jobs involving software architecture, modeling and IS architecture that I conducted for large organizations in the banking and industry sectors.
The point of view that I will develop is that mastering complexity involves two essential steps: first, a clear understanding of the nature of complexity within the IS should be developed, second, one should identify the primary causes which contribute to its uncontrolled growth and organize these into a logical framework in order to define efficient countermeasures. Both technical and psychological causes of complexity will be considered. The relation with IS value will be discussed.
