OGEA-101 The Open Group Exam Lab Questions

The planning horizon, depth, and breadth of an Architecture Project, along with the contents of the EA Repository, are typically framed by Strategy, Portfolio, Segment, and End-to-end Target Architecture. The ' Segment ' refers to a part of the organization, typically addressed in a Segment Architecture, while ' End-to-end Target Architecture ' encompasses the complete view of the planned architecture across the entire organization.

“TOGAF defines **‘enterprise’ as any collection of organizations that has a common set of goals. For example, an enterprise could be a government agency, a whole corporation, a division of a corporation, a single department, or a chain of geographically distant organizations linked together by common ownership.”

Gap Analysis in TOGAF is a technique used to compare the baseline architecture (current state) with the target architecture (future desired state). The output is a set of gaps, representing what is missing or what must change to move from baseline to target. These gaps help validate that the target architecture is adequate: by identifying what is not addressed, architects can ensure that all required functionality, constraints, and transformation paths are captured. In effect, Gap Analysis validates the architecture by exposing omissions, inconsistencies, or unmet requirements between what is and what should be. It is not primarily about defining service levels, nonfunctional requirements, or quality metrics (though it helps inform those). Rather, its main role is in validating and guiding closure of architectural gaps.

Phase E: Opportunities & Solutions – Steps/Outputs emphasize grouping work packages, dependencies, and planning the roadmap/plan that reflect value/effort:

“Identify and group major work packages… Refine and validate dependencies… Create the Architecture Roadmap & Implementation and Migration Plan.”
