My first question was the extent to which TOGAF 9 addresses some of the SOA issues that have been overshadowing TOGAF 8 for over five years. I was particularly pleased to see the emphasis on Business-Led SOA (section 22.3).
In addition, there are some new or enhanced areas that look exciting.
- Architectural Partitioning- this abstracts away from the specific rows and columns of the Zachman matrix, while retaining the underlying principle of articulating different architectural views and domains in a systematic manner
- Business Capability Management - following the lead taken by the architectural frameworks of the defence world (DoDAF and MODAF), but applying a high-level concept of business capability to the civilian world. For example, the TOGAF guide points to the relevance of concept for governments in planning horizontal interoperability and shared services. Excellent.
- Content Framework. A generic reference framework for architectural deliverables.
- Enterprise Continuum. This concept was already present in TOGAF 8.1, but is now much clearer, for example in the way it talks about the general and the specific.
- Holistic Enterprise Change. This is mentioned as one of the benefits of TOGAF 9, but there is (as yet) little substance behind this. Clearly an area for further work.
