Death by Governance
Don’t overshoot
SOA Requires Governance
Asset Governance is a (1) Process with checks & balances and (2) People with defined decision rights, measuring compliance with a set of (3) Policies, producing (4) Metrics so that good business decisions
can be made involving technology and full adherence may be achieved in the fullness of time
SOA by its nature enables a federated development process with individual groups producing individual services relatively independently.
This enables scale (supporting agility) , but requires trust. Only via a well defined set of interface guidelines, policies and a Governance process can you keep complexity under control.
