On a hybrid project, differing interpretations of requirements caused deliverables to not meet expectations. What should the project manager have done to prevent this?

The correct answer is ensuring the team receives continuous feedback from customers and users. In a hybrid project, especially with evolving requirements, continuous feedback loops are crucial for validating understanding and ensuring deliverables align with expectations. This proactive approach helps identify and correct misinterpretations early, preventing significant rework. Ensuring the team understands every additional project requirement is important but insufficient; understanding alone doesn't guarantee alignment with evolving customer needs. Updating the project management plan to get back on track is a reactive measure, addressing the symptom rather than the root cause. Submitting a change request to adjust the project scope is also reactive and may be necessary after the issue occurs, but it doesn't prevent the initial misinterpretation.
