Governance and Conceptual, Logical and Installed Architecture Alignment Using Work Products and Workflow

Governance and related alignment methods for the management of complex systems are introduced here to facilitate and better decision making. The goal here is to increase re-use and agility. We also show how EA governance can leverage technologies like middleware and workflow to enable service evolution. The methods and work products of the previous Chapter 2 along with the following EA layers guide continual service improvement. What is the ACE EA governance? • How is the organization established? • What are the goals and benefits of EA governance? • What are the different roles and responsibilities of the EA team? How does the Conceptual ACE structure guide the EA team to make enhancements to the Logical and Installed architecture layers?
