None, The FEAC Institute has built its curriculum based upon a zero-competency model. New or inexperienced enterprise architects focus on building basic vocabulary and competency in the program's first three weeks. For more experienced architects, expectations and differences in experience are level set against a curriculum built around International Organization for Standardization (ISO) enterprise architecture standards. This approach provides something for both new and experienced architects during the program's first three weeks (e.g., Certified EA Practitioner/Yellow Belt). Course complexity progresses from week four onward with an increasing focus on architecture practices and analysis approaches.
