What should be proposed to the team?

Agile promotes cross-functional teams and reducing bottlenecks through knowledge sharing and skill development. The PMI Agile Practice Guide (Section 4.3.3: Cross-functional Teams) recommends that team members develop T-shaped skills to handle more types of work. Mike Griffiths in the PMI-ACP Exam Prep Book (Chapter 3: Team Performance) advocates for skill broadening to improve team throughput and resilience.

Option A is correct: cross-training removes dependencies and improves flow.

Option B delays action and prolongs the issue.

Option C reduces delivery capacity rather than addressing the root cause.

Option D arbitrarily limits scope and doesn’t resolve the underlying skill gap.
