SOA Governance is the key to a successful adoption of Service-Oriented
Architecture. It is the process of establishing a desired outcome for
your efforts, and then leveraging people, policies, and processes to
make that outcome a reality. This includes technical policies and
standards that guide your design-time activities, policies and
processes that impact your project selection and funding decisions, and
finally run-time policies that impact your operational management
activities.
