He holds positions on the CBI's Innovation, Science and Technology (IST) working group, as well as with PITCOM and EURIM, and is a Chartered Fellow of the BCS, a Fellow of the IoD and a Senior Member of the IEEE. Wayne writes one of the most popular Sun blogs at:

Large (and, increasingly, smaller) enterprises have embraced Enterprise Architecture as a key tool to interpret and strategically manage the complexity of their IT estates, and it's not surprising that many of them have assembled large teams and spent many millions of pounds to achieve an 'Enterprise Architecture'.

The case studies presented explore Wayne's experiences with Enterprise Architecture in three major customer engagements. They include an Enterprise Architecture team which led its company into a ú70+ million 'pitfall'; the use of Enterprise Architecture to define a Service Oriented Architecture; and an example of how much Enterprise Architecture is about achieving the proper governance model.

Key takeaways:

  • Enterprise Architecture best practices drawn from multiple engagements.
  • How to use good governance to avoid and limit the 'Ivory Tower' syndrome.
  • How to combine Enterprise Architecture and Service Oriented Architecture to deliver sustainable Transformation
