Agile teams evaluate new tools or technologies throughspikes-time-boxed research or experimentation tasks. According to thePMI Agile Practice Guide (Section 5.2: Spikes and Exploration)andMike Griffiths' PMI-ACP Exam Prep Book (Chapter 6: Adaptive Planning), the appropriate way to introduce new technology is toengage the teamin the decision and create abacklog itemfor a spike to evaluate its viability.
* Option Cis correct: it follows agile collaboration and backlog grooming practices.
* Option Askips team consensus and formal prioritization.
* Option Bcontradicts self-organizing team principles.
* Option Dmay delay necessary action and is better suited for process discussions, not technical trials.

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.

The correct answer is D - Assume the team member's tasks to meet iteration goals and notify the Product Owner. Agile teams are self-organizing and accountable. High-performing teams take ownership of shared goals and redistribute work as needed to maintain commitment.
From the PMI Agile Practice Guide:
"High-performing agile teams collaborate to deliver sprint goals, adapting to changes such as unavailability of team members. They adjust workload and communicate impacts transparently." (PMI Agile Practice Guide, Section 4.3 - Team Performance and Self-Organization) Mike Griffiths explains:
"When team composition changes, the team must redistribute work to ensure delivery. Ownership, trust, and flexibility are core traits of high-performing agile teams." (Mike Griffiths, PMI-ACP Exam Prep, Chapter 4 - Team Performance) Incorrect options:
* A signals dysfunction and abdicates team responsibility.
* B implies external management of team staffing.
* C violates the principle of self-organization.

The correct answer is A - Provide feedback for completed user stories.
Stakeholder involvement in Agile is ongoing. Their primary role is to give timely and actionable feedback on delivered product increments to ensure alignment with their expectations and business value goals. This feedback is then used to refine the product backlog and guide future iterations.
PMI Agile Practice Guide:
"Stakeholders should engage regularly to inspect product increments and provide feedback to guide value delivery." (PMI Agile Practice Guide, Section 4.2 - Stakeholder Engagement) Mike Griffiths:
"In agile projects, stakeholders ensure their needs are met by actively reviewing completed work and providing feedback to influence upcoming work." (PMI-ACP Exam Prep, Chapter 3 - Value-Driven Delivery) Incorrect options:
* B is the team's responsibility; stakeholders should focus on the "what," not the "how."
* C is the product owner's responsibility.
* D is a collaborative task but not solely a stakeholder responsibility.

According to thePMI Agile Practice Guide (Section 7.2.2), one of the key responsibilities of the agile practitioner is toactively engage stakeholdersthroughout the development cycle-not just during review meetings. Agile frameworks promote continuous collaboration and frequent feedback. Merely attending sprint reviews is passive participation and may lead to missed alignment on expectations.
Mike Griffiths also emphasizes in hisPMI-ACP Exam Prep Book (Chapter 4: Stakeholder Engagement) that stakeholder satisfaction requires more than periodic visibility-it requiresongoing interactionand inclusion in decision-making and backlog refinement sessions. This deepens shared understanding and reduces the risk of late-stage surprises.
Hence, answerBis correct because proactivestakeholder engagement with the product ownerfosters mutual understanding, timely feedback, and course correction-ensuring the product aligns with expectations.
