Hi Rahul,
Recognizing the contributions of the high-performing team members is part of the Develop Team process. Recognition and rewards are detailed there as one of the seven Tools & Techniques. The project manager can use the relevant OPAs to guide them through this process and provide the team members with the appropriate rewards and recognition.
I see from your Lessons Learned that you just passed the PMP exam. Congratulations!
Time to reward yourself, Rahul Vadakke Veetil, PMP!
