The correct answer is D - Encourage self-organization by communicating the importance of a collaborative approach in decision making about the requirements. Agile teams thrive on collaboration and shared ownership. When conflicts arise between stakeholders and team members, the project manager (or Scrum Master) acts as a facilitator to encourage respectful discussion and team-driven decisions. Agile emphasizes self-organization, transparency, and frequent collaboration between customers and teams. From the PMI Agile Practice Guide: "Agile encourages ongoing stakeholder engagement and collaborative decision making. The Agile leader helps teams self-organize and resolve issues through direct communication and mutual respect." (PMI Agile Practice Guide, Section 4.2 - Stakeholder Engagement) Mike Griffiths explains: "Agile promotes co-creation. The project manager's role is to facilitate dialogue, not dictate requirements. The best outcomes come from collective decisions aligned with value." (Mike Griffiths, PMI-ACP Exam Prep Book, Chapter 3 - Stakeholder Engagement) Other options explained: * A contradicts Agile principles of team and stakeholder collaboration. * B gives unilateral authority to the customer, which can disrupt team ownership. * C excludes the team from the conversation, weakening transparency.
