Hi Deepak,
Not sure if I understand your question correctly, are you looking for a list of example of how to collect customer/stakeholder feedback, measure overall project performance and project review techniques?
I don't have all the examples but I can get the ball rolling:
1. Feedback
-Surveys and questionnaires
-Interviews
-Meetings (customer wrap-up)
2. Performance measurement
from PMBOK6, pg 126
-Document analysis
-Regression analysis
-Trend analysis
-Variance analysis
3. Project review
-Meetings (learns learned, close-out reporting)
-Expert Judgement
