When speaking of evaluation, there are performance measurement and monitoring, both of which concern the output and outcome. However, is there any difference between these two terms?

You are welcome.

Thank you. It solves my puzzle!

That's a good question. Performance measurement is mainly for the external report to stakeholders that may increase the transparency of funds used, while monitoring is more about internal tracking, to make sure your program is in the right direction and keeps pace with your goals.
