Many organizations seem to hit the brick wall on SOA when one of four things happen:
1. Their isn't a critical mass of SOA enthusiasts
2. No one will pay for SOA infrastructure
3. No model for funding or governing shared services exists
4. Doing SOA right requires a reorganization of I.T.
Simple SOA is primarily directed at the 4th problem. Most I.T organizations have groups that "own applications" or dare I say, they "own monolithic, tightly coupled applications" - they don't own "shared services" (business or technical). Doing SOA right usually requires a new I.T. reporting structure but this can be a SLOW process.
So, the second concept I'm promoting is the use of an SOA Steering Committee.
As I mentioned in my last post, an early (and easy) step to take is having project teams leveraging the enterprise disciplines. Application architects should be working with their counterparts in EA, etc. Once the project teams begin communicating with the enterprise disciplines, the natural progression is to get all of the enterprise disciplines talking to each other.
The agenda for a typical SOA Steering Committee is:
10 minutes - The status of the SOA Roadmap: what is done and what isn't
20 minutes - A review of any new artifacts or SOA deliverables
20 minutes - A discussion on problems that the project teams are encountering
10 minutes - Recommended changes to the SOA Roadmap
It's a simple meeting that is cross-discipline. The team uses a program plan (SOA Roadmap) to keep a list of initiatives visible. The roadmap remains 'agile' and reacts to findings in the field. A fundamental goal of the team is to address issues that pop up quickly and to take decisions back to their respective teams.
In the beginning the team will likely meet often (every 2-4 weeks) and as the program matures the team will probably meet quarterly or until stabilization is realized.
