The correct answer is B - Ensured the early engagement of key stakeholders. Agile emphasizes early and continuous stakeholder involvement. In this case, engaging enterprise architects and standards stakeholders early in the design process would have helped detect conflicts before sprint execution.
From the PMI Agile Practice Guide:
"Key stakeholders should be engaged early in the development cycle to ensure alignment with organizational policies, standards, and expectations." (PMI Agile Practice Guide, Section 4.2 - Stakeholder Engagement) Mike Griffiths notes:
"Involving stakeholders early helps mitigate the risk of late surprises and rework. Enterprise architects should be consulted during backlog grooming or prior to sprint planning." (Mike Griffiths, PMI-ACP Exam Prep, Chapter 3 - Stakeholder Engagement) Incorrect options:
* A is reactive and escalatory.
* C presumes the standards are flawed without analysis.
* D ignores necessary compliance and does not solve the issue proactively.
