I think the answer is A. This question is talking about the unclarity of the requirement. So the best option is to clarify the requirement with stake holders. If you go with answer D, again rework may be expected on the prototype until the requirement is clear and all are on the same page.

This problem is not interpreted as a problem with stakeholders, but rather as a lack of understanding among team members due to physical distance. This needs to be resolved by creating a prototype among team members.

While A would help clarify requirements, it relies on verbal or written communication, which can still be misinterpreted, especially in cross-cultural or remote teams. D addresses the root cause more effectively by providing a shared, visual understanding of what needs to be developed.

A is correct answer

since customer knows what he wants, why create prototype? I think A is correct

Option D takes a more practical and visual approach that directly demonstrates the software functionalities, potentially aiding in faster alignment and reducing the chances of misinterpretation or rework.

'identified completion date delays due to rework because there were different interpretations of the client's needs' highlight delay and interpretations are clarified and so, rework is decided/ongoing. In that case, what clarification is needed with customer. There is only one impact which is delay in schedule and only option here is to escalate.

rework menaing thye already have examples and still disagree so go to the source for clarification with all involved.

Prototypes is the correct tool to clarify well the requirements.

A. Set up a meeting with key stakeholders to clarify requirements

The question mentions PM has observed this issue in "progress reviews". So, it has happened multiple times. If the scenario involves delays due to different interpretations of client needs during progress reviews, then the need for a consistent practice like preparing prototypes becomes even more important.

Option D- Starting with creating prototypes (option D) and following up with a meeting with key stakeholders (option A) to ensure that the prototypes accurately reflect their expectations could lead to the best outcomes.

Why D? They are reworking already due to diff interpretation. Yet still need to do a prototype? Waste of time and resources. Shld clarify the requirement immediately to avoid further rework and delay. Answer is A

The delays in completion date indicate a problem with requirements interpretation. Clarifying requirements can help to prevent this kind of problem from happening in the future. The project manager should bring together key stakeholders from both teams to review the requirements and ensure everyone is on the same page. This can help to prevent further rework and schedule delays.

D is right, because A says "KEY stakeholders".....

I will go with A. Rework only happens when you do not satisfy client needs and requirements. Since there are different interpretations of client's needs, it is best to meet with the client and clear it for once and all. This will remove the confusion all teams will work towards the same requirements/goals.

I think D is correct. Because, keyword: rework because there were "different interpretations" (in team). I think requirement from client is still clear.
