A senior engineer reviews the current plan and notices that one key control is missing. For IBM Certified watsonx Mainframe Modernization Architect, the topic is SME collaboration. What should the team do?

Here's the deal: think of SME collaboration like labeling the cables before you close the rack door. If you skip that discipline, troubleshooting gets ugly fast. In this scenario, answer D is the practical move because it keeps the implementation tied to the real IBM capability instead of chasing a shortcut. The other choices sound tempting, but they either skip governance, ignore operational reality, or solve the wrong problem.

The correct answer is D. Keep mainframe SMEs involved to confirm business meaning and edge cases. That aligns with the Domain 5: Refactor Mainframe Applications into Modular Components objective because it applies the feature or practice in the context where IBM expects a practitioner to use it. It also keeps the design reviewable, supportable, and realistic for a production environment.

Let's examine why the other options are incorrect: - Option A is incorrect because it sounds related, but it does not solve the SME collaboration requirement described in the scenario. - Option B is incorrect because it sounds related, but it does not solve the SME collaboration requirement described in the scenario. - Option C is incorrect because it narrows the solution to one artifact or metric and misses the broader SME collaboration requirement. For the exam, connect the feature to the operational outcome: the right answer is the one that preserves control, accuracy, and maintainability instead of relying on a brittle shortcut.
