A project is scheduled to end in 2 weeks.

One of the ways to ensure success in a project is by motivating team members. As the project progresses, stress levels increase, and overall, things turn hostile. All this reduces the motivation of the team1. One of the crucial reasons behind project success is high project team motivation. Organizations with higher-than-average levels of employee engagement see 27% higher profits, 50% higher sales, 50% higher customer loyalty levels, and 38% above-average productivity1. Therefore, initiating rewards and incentives according to assessment results can be an effective way to encourage the team and boost their performance. References:
