Kerr earned a BSc (Hons) in electronic and electrical engineering from Robert Gordon's in Scotland. He is a member of the Project Management Institute and the Institution of Electrical Engineers, and is a Chartered Engineer (CEng) and a Project Management Professional (PMP). Primary expertise Program and Project management - Has lead and delivered many development projects's and programs successfully.  Recovering problem projects is a specialty

Enterprise Architecture -
Has developed architectures from scratch or adapted them using a System of Systems architectural approach.

Software Development Lifecycle - Has adapted, customized and constructed development methodologies to fit client needs.

Recent client experience 2006 Energy Market - Program Design - helped set up a major program to implement fundamental changes to market rules.

2006 Energy Market - Enterprise Architect - Provided enterprise architecture advice for the overall system, with a System of Systems & UML.  An overall architecture was produced that integrated best of breed heterogeneous applications.

Enterprise Architecture and Enterprise Integration
The greatest risk for any enterprise level project is integration. Success in implementing enterprise level projects depends on joining up business and integration processes within the context of a total enterprise architecture.  The following big ideas will help your enterprise project really succeed:

• Big Idea 1 - Create a clear business process picture of the core enterprise processes impacted
• Big Idea 2 - Analyze from the bottom up by inventorying your information flows between business functions & systems
• Big Idea 3 - Identify integration processes from the top down, link to enterprise business processes and map to information flows
• Big Idea 4 - Define your enterprise integration processes and forget the technology (for now)
• Big Idea 5 - Recognize you need a system to implement your enterprise integration processes
• Big Idea 6 - Organize yourselves so that you can be successful
• Big Idea 7 - Be prepared for hard work

Case Study: SOA and the Electricity Reliability Council of Texas
ERCOT is the Independent System Operator for electricity in Texas and are restructuring their wholesale market from a 5 zone pricing system to a nodal system with 1000s of settlement points. ERCOT selected a best of breed approach for the main system components and chose to factor out system integration from any one system vendor.

A SOA lies at the heart of the technology to support the restructuring effort that provides:

• a set of web services for external Market Participants to interact with the market
• an Enterprise Service Bus to fulfill internal information flow

The challenge of the project has several drivers:

• The scale of restructuring the market rules
• Increased number of systems to control the grid & market
• Transforming multiple point to point to an ESB
• replacing screen scraping with web services
• agreed by many Market Participants
• building a SOA while the end point systems are being developed

The solution has addressed:

• Developing a system engineering approach called System of Systems Architecture to model behavior of the overall enterprise
• Developing components of the SOA in advance of the underlying systems
• Creating an integration factory to deliver the components of the SOA
• Changing from a waterfall SDLC to RUP
• Delivering external interfaces to the market 18 months before go-live, to ensure market participation
