The correct answer is D – Increase the opportunities to confirm common understanding with the client.
The rise in defects and change requests indicates a disconnect between what the team is delivering and what the customer expects. Agile emphasizes constant feedback and collaboration. Ensuring shared understanding through frequent interaction and validation reduces misunderstandings and rework.
From the PMI Agile Practice Guide:
“Frequent interactions with customers and stakeholders help teams build a shared understanding and reduce the risk of misaligned expectations and defects.”
(PMI Agile Practice Guide, Section 4.2 – Stakeholder Engagement)
Mike Griffiths explains:
“A high defect rate often results from unclear requirements. Teams should improve communication loops with stakeholders to confirm understanding before development begins.”
(Mike Griffiths, PMI-ACP Exam Prep Book, Chapter 6 – Problem Detection and Resolution)
Why the other options are suboptimal:
A doesn’t address the root cause: misalignment with the client.
B is reactive and temporary, not a sustainable solution.
C may help but should be preceded by improving collaboration and understanding.
