An agile team must maximize delivered work on a project with significant product complexity. What should the project manager do to improve the team's collaboration?

The correct answer is to focus on engaging the team during the next retrospective to improve collaboration. Retrospectives are a core agile practice designed for continuous improvement, where the team inspects its processes and adapts. This provides a dedicated, structured opportunity for the team to identify collaboration issues and collectively devise solutions, directly addressing the problem. Meeting with HR for additional support is less effective because collaboration issues are often internal team dynamics, not resource shortages. Adopting another team's process might not fit this team's unique context or complexity, and could be disruptive. Comparing velocity against other teams is a metric for performance, not a direct action to improve collaboration, and can lead to unhealthy competition rather than improvement.
