Architecture governance	The management of an architecture (in development or operation) so as to ensure it conforms to pre-defined architectural requirements, principles, policies and models.
Architecture board	The group of people who maintain architecture principles and governance processes, and appoint governing architects.
Architecture contract	A document that defines those architectural requirements, principles, policies and models that a system should conform to as it is built and when it runs. Also defines any architecture stakeholder rights and interests that must be met.
