TOGAF Business Architecture Foundation — Question 10

Consider the following:
In Phase A a business capability map and a core set of value streams were created while developing the Architecture Vision.
Why would such Architecture Descriptions need to be updated in Phase B?

Answer options

• A. Phase B requires that all Architecture Descriptions be updated.
• B. The development of Business Architecture Descriptions is always iterative.
• C. Phase B is an ADM Architecture Development phase.
• D. A new value stream was assessed as in the project scope.

Correct answer: B

Explanation

The correct answer is B because the development of Business Architecture Descriptions is inherently iterative, meaning they evolve as new insights and requirements emerge. Option A is incorrect because not all descriptions require updating; it depends on the context. Option C is not the reason for updates, as it simply states the phase's classification. Option D does not apply to all cases, as updates may not always stem from a new value stream assessment.
