Governing SOA is a full time job.
Actually, for most large organizations - it requires a team of professionals, highly trained in SOA Governance, Architecture and Operational Management.
MomentumSI offers an organization the ability to outsource either all or part of their SOA Center.
Some of the world's largest corporations rely on Momentum to provide outsourced SOA Governance Centers.
In some cases the initial focus is on an "SOA Center of Excellence" (CoE) where the goal is to provide advice and guidance on SOA initiatives.
The SOA CoE typically evolves into a more comprehensive organization that provides planning, management, and governance of service based projects.
It is also common for the Center to provide a shared instance of SOA Infrastructure.
The Center quickly becomes the hub of all SOA activity - aligning enterprise wide initiatives.
