The correct answer is C - The team should have conducted more demonstrations with the product owner during the iteration.
Continuous feedback is essential in Agile. Regular product demos or interim check-ins during the sprint (not just at the end) allow the product owner to validate progress and course-correct early. This ensures that expectations are aligned and surprises are avoided at the sprint review.
PMI Agile Practice Guide:
"Stakeholder feedback should be gathered continuously throughout the sprint. Regular engagement and interim demos reduce the risk of misalignment at iteration end." (PMI Agile Practice Guide, Section 5.7 - Reviews and Demos) Mike Griffiths:
"Waiting until the sprint review to validate features with the product owner increases risk. Frequent collaboration and demonstrations ensure the work remains on target." (PMI-ACP Exam Prep, Chapter 3 - Value-Driven Delivery) Incorrect options:
* A is helpful but doesn't guarantee alignment.
* B is testing-focused and misses early collaboration.
* D places all responsibility on the product owner, ignoring shared ownership.
