Biography and current work


Research, teaching and consulting in systemic methods for strategic thinking, enterprise architecture and requirements engineering.


Alain Wegmann joined EPFL in 1996. His interests are in techniques to better align business and IT. He developed, with his group and partners, the SEAM methods: SEAM for business (strategic thinking), SEAM for enterprise architecture (business/IT alignment) and SEAM for software (IT). The originality of SEAM is in the integration of generic systems thinking principles into discipline-specific methods. This integration has three benefits: (1) the possibility to relate the different disciplines (by having common systemic principles); (2) the capability to leverage on discipline-specific knowledge (by using the vocabulary and the heuristics of each discipline) and (3) to be more efficient in solving problems (by benefiting from the problem solving techniques developed in systems thinking). SEAM is currently applied in master courses and consulting. Consulting is done for start-ups developing their business and technology strategies and for large companies having service-oriented architecture projects.

Prior to joining EPFL, Alain Wegmann worked for 14 years with Logitech in software development/engineering management (Switzerland, Taiwan, US), manufacturing (Taiwan) and marketing (US). When he left Logitech, Alain Wegmann was engineering vice-president and marketing director for large accounts.


1. (Academic) Overview of the SEAM method:

This paper presents the foundations behind SEAM. In particular, it introduces the systemic modeling paradigm on which SEAM is built. Reading this paper is useful for people who want to understand the paradigm (i.e. set of principles) underlying SEAM. However, it is not necessary to read this paper to use SEAM.

2. Example of SEAM for Business:

This paper illustrates the use of SEAM for Business to analyze the WWW communication strategy of a consulting company. This illustrates how SEAM can be applied to model the relations to the customers as well as the business strategies. This model can then drive, for example, the redesign of the company web site.

Early Requirements and Business-IT Alignment with SEAM for Business

3. Example of SEAM for Enterprise Architecture:

This paper illustrates the use of SEAM for EA in the context of a company that needs to align the business and the IT strategies. We present an enterprise model that spans from business down to IT. Such models are used in consulting and in teaching. The second paper presents our course on this topic.

4. Example of SEAM for Software:

This paper illustrates how SEAM can be used to model a software architecture. We present the SEAM model of the PetShopStore (case study intially used to document J2EE architectures).

Development of methods and tools for "strategic thinking" and "business / IT alignment". The current research topics are: service level management, alignment of business and IT strategies, IT systems to support coopetitive strategies, and integration of service/goal/process models. The research is currently funded by EPFL, SNF and industrial partners.
