The correct answer is A - Teach the team the appropriate agile principle, obtain consensus, and drive adoption.
Agile values "working software over comprehensive documentation." However, this does not mean eliminating all documentation, but rather focusing on documentation that delivers value.
PMI Agile Practice Guide states:
"Agile teams should regularly question whether the work being done adds value, including documentation. If documentation does not serve a current need or stakeholder, it should be minimized or eliminated." (PMI Agile Practice Guide, Section 2.2 - Agile Manifesto) Mike Griffiths further supports this in his exam prep book:
"Agile team members are encouraged to surface inefficiencies and suggest improvements. This is an example of continuous improvement and shared responsibility." Option A aligns with both the Agile Manifesto and the principle of team empowerment. Options B, C, and D either avoid accountability or introduce hierarchy that agile teams seek to minimize.

The correct answer is A - Hold a meeting with the team and the Product Owner to develop the team charter, working agreement, guiding principles, and product vision. This collaborative approach fosters shared understanding, ownership, and alignment early in the project.
From the PMI Agile Practice Guide:
"The team chartering process includes developing working agreements, clarifying the product vision, defining team norms, and establishing the team ' s mission. Early alignment builds trust and commitment." (PMI Agile Practice Guide, Section 4.3 - Team Charter and Working Agreements) Mike Griffiths elaborates:
"A strong start includes co-creating team values, the product vision, and working agreements. Doing this together builds a strong foundation for delivery." (Mike Griffiths, PMI-ACP Exam Prep, Chapter 2 - Agile Principles and Chapter 4 - Team Formation) Incorrect options:
* B separates the Product Owner from the team early on.
* C reverses the roles-vision should be owned by the Product Owner.
* D is helpful, but not a prerequisite for team alignment and success.

The correct answer is C - Conduct retrospectives at the end of every sprint.
According to the Agile framework, regular retrospectives are a key practice to inspect and adapt the process.
If team members have concerns about the Scrum Master ' s processes, the appropriate time and space to bring up and resolve such issues is the Sprint Retrospective.
From the PMI Agile Practice Guide:
"Retrospectives are a time-boxed event that enables the team to inspect itself and create a plan for improvements to be enacted during the next iteration. It provides a structured opportunity for feedback and reflection." (PMI Agile Practice Guide, Section 3.5, Iteration Retrospectives) Mike Griffiths further adds:
"Teams must take ownership of their process. The role of the agile leader, such as a Scrum Master, is to facilitate improvement via mechanisms like retrospectives. They are not responsible for enforcing process, but for enabling continuous improvement." (Mike Griffiths, PMI-ACP Exam Prep Book, Chapter 4 - Team Performance) Why the other options are incorrect:
* A may undermine the team ' s self-organization and brings hierarchy into team-level process adjustments.
* B may address some confusion, but doesn't actively involve the team in process improvement.
* D is inappropriate-sprint planning is for work planning, not process feedback.
Therefore, the most agile-appropriate and validated solution is: C

The Minimum Viable Product (MVP) is the smallest set of features needed to satisfy early adopters and deliver value quickly while enabling further development based on feedback. From the conversation:
Android phone integration: The customer specifically asks if they can connect their phone to the calendar app, so integrating with Android is a key MVP feature.
Scheduler to add events: The customer requests the ability to schedule and manage upcoming releases, including quarterly metrics deadlines and other key dates. This is fundamental functionality for the calendar app.
Product increment release dates: The customer wants the calendar to show release dates, so having the ability to display product increment release dates is essential.
