A team is trying to meet milestone dates to earn a sponsor bonus. Unforeseen problems and poor communication caused mistakes and delays. Tensions are high and the sponsor is concerned. What should the project manager do?

The project manager's primary responsibility is to achieve project objectives. By discussing with the team how objectives can be met, the project manager facilitates problem-solving, re-planning, and re-engagement, directly addressing the core issue of missed milestones and delays. This approach empowers the team to find solutions and fosters a collaborative environment. Scheduling a team-building activity might temporarily boost morale but doesn't resolve the underlying performance and communication issues. Asking the sponsor to increase the bonus is inappropriate and doesn't address the current performance problems. Holding a meeting to remind everyone of ground rules might be part of a solution, but it's less proactive and problem-solving oriented than directly discussing how to meet objectives.
