Our approach to stabilising, standardising and optimising EA in an organisation is based on the following principles:

• Clearly defined EA products and services to be delivered to the EA customers.
• A meta-model defined and implemented on architectural principles enabling effective repository management and quality modelling.
• EA governance implemented by a central EA office.

During the Plan and Build phases, the products are delivered according to a defined and agreed project scope. The Run phase is usually delivered as an outsourced or co-sourced service to the organisation.
