The correct answer is B - Ensure there is a balanced mix of people who are experts and members with broad experience based on the work to be performed and determine training needs.
Scrum encourages cross-functional, self-organizing teams with complementary skills. Building a balanced team that reflects both depth and breadth of experience ensures optimal delivery while enabling team learning.
From PMI Agile Practice Guide:
"Agile teams are cross-functional. The team may need T-shaped skills-members with deep expertise in one area and a willingness to broaden knowledge in other areas. Creating balanced teams with knowledge diversity leads to better collaboration and learning." (PMI Agile Practice Guide, Section 4.1 - Building Agile Teams) Mike Griffiths adds:
"Team selection should prioritize diversity of skill sets and the ability to collaborate, not just performance history. The goal is a team that can deliver value collectively, not as individuals." (Mike Griffiths, Chapter 4 - Team Performance) Why the other options are not suitable:
* A may reduce team diversity and discourage healthy conflict resolution.
* C may not be feasible in distributed environments and is not a strict requirement.
* D focuses on individual velocity contributions, which contradicts Agile's team-based delivery focus.

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.
