A project manager consolidates metrics in an agile project and finds team productivity has declined: items sent to development per person dropped 10%. RCA shows a knowledge gap in a modeling framework. What should the project manager do next?

Fostering knowledge sharing and coaching among team members is the most effective and agile solution. This approach leverages existing team expertise, promotes internal growth, and addresses the knowledge gap directly within the team's context. It's also cost-effective and builds team resilience. Adding new members might temporarily increase output but doesn't solve the underlying knowledge gap and can disrupt team dynamics. Hiring an external expert is costly and doesn't build internal capability. Arranging external training, while potentially helpful, is a slower, more expensive option that might not be immediately available and could further strain tight schedules.
