The Open Group OGEA-103 Question Answer
What concept enables the simultaneous operation of multiple ADM phases?
Iteration
Change Management
Digital Transformation
Transition Planning
Comprehensive and Detailed In-Depth Explanation from Expert in Enterprise Architecture, guiding in TOGAF and ArchiMate:
TOGAF explicitly allows the ADM to be executed in a non-linear and iterative manner.
Iteration enables:
Multiple ADM phases to be active at the same time
Overlapping work across architecture domains
Incremental refinement of architectures
Agile and responsive architecture development
Why Option A is correct:
Iteration is the TOGAF mechanism that enables simultaneous and repeated execution of ADM phases.
Why the other options are incorrect:
B. Change Management: Controls change, but does not enable parallel ADM execution.
C. Digital Transformation: A business initiative, not an ADM execution concept.
D. Transition Planning: A specific planning activity, not an execution model.
