The project has a very tight delivery schedule. As the delivery date approaches, the sponsor frequently warns the project manager to avoid any schedule slippage. The team has performed acceptably so far, and the project manager wants to maintain that performance through completion. What should the project manager do to motivate the team's performance?

Awarding certificates of appreciation is a positive reinforcement strategy that recognizes the team's efforts and motivates them to maintain their performance. This aligns with motivational theories emphasizing recognition and achievement. Sending a formal notice could be demotivating and may not improve performance. Hiring temporary team members might introduce new team dynamics, require onboarding, and could potentially slow down progress rather than accelerate it, especially with a tight deadline. Informing the team about sponsor pressure could increase stress without providing a clear path for improvement or recognition for their current efforts.
