Teaching EA
My colleague, John Gøtze has asked me to teach his course on Enterprise Architecture (see T8) at the IT-University of Copenhagen today. The theme is Service-oriented architecture and Henrik Hvid will join me for one of the three hours. The agenda will be as follows:
1) Introduction - Learning objectives and brief introduction to PhD-Project
2) Linking SOA and EA - Why we use SOA to create interoperability
3) SOA in theory and practice - Theoretical foundation short and lessons learned from a case study in a Nordic bank
4) SOA by Henrik Hvid
5) Case: Public sector infrastructures and SOA
Please feel free to stop by room 2A12 at ITU if you have time ;-)

PhD-presentation in the National Enterprise Architecture Committee
Thursday last week, I presented my PhD in the National Enterprise Architecture Committee. It was great to see the "family" again; The committee was established right before my PhD and therefore paved the way for my project. The members were positive towards my accomplishments so fare and they encouraged me to continue my case studies and the literature survey.
The presentation was scheduled to last half an hour, but due to a very lively discussion I almost presented for one hour. Below, I have highlighted some of the most important feedback:
1) The committee found the institutional coordination aspects in my PhD interesting - but they are very complex and difficult to generalize across government domains.
2) The sector concept in my first article must be defined better. A clear distinction must be made between the levels of government and sectors.
3) Interoperability is not one-dimensional. I have used the EIF in a couple of my articles and the committee encouraged me to work more with the three dimensions.

Meeting with Bob Sutor
Yesterday, I met with Bob Sutor from IBM. We discussed open standards in the public sector and how they affect the architectures that we build in government over the next couple of years. Bob is the vice president of standards for the IBM Corporation and really knows what he is talking about. For me, his thoughts on interoperability are very interesting and I recommend everybody to read his blog on developerworks.

Defining Interoperability
I think that most people would agree that creating interoperability requires more than just having a common technical standard or using XML to create technical integration between two applications. Therefore, inspired by Park & Ram (2004) and the IDA EIF I am working on a broader definition:
Interoperability is the ability of information systems and the business processes they support to exchange data and enable sharing of information.
From a top-down perspective John Gøtze and I in our ECEG04 paper outlined the solution to the interoperability problems in government via a model where all institutions involved follow the same standardized framework for organizational, semantic and technical interoperability. But, in reality this is hard to accomplish! Thus, if anybody has a better definition of interoperability or references to good literature about the subject, please let me know.
