What are some examples of artifacts at the Goals & Initiatives level of the EA3 Cube Framework?

Current Strategic Scenario, Strategic Goals, Initiatives, Measures.

What is the IDEF-0 modeling technique and how can it be used to document EA components at the Business Level of the EA3 framework?

The Integration Definition for Function, or IDEF technique. Developed in the mid-1970’s for modeling complex military projects, IDEF-0 uses Inputs, Outputs, Controls and Mechanisms (ICOM) to show the parts of an activity within an enterprise. IDEF-0 activity modeling is suitable for business process documentation in that it provides both high level context views, and more…
