Thanks for the comments and suggestions. Sincerely appreciate it.
- Regarding the error with the study design, it's not my opinion. A said it herself. B knew it too. Everyone was in the room when we reviewed it.
- I don't agree about your comments on capability though. A knew the history of the project. In this regard, it's better for the project to be handled by A. I agree she has more knowledge on this project than me, since she has worked on this product for >2 years.
- I have many other projects with B. Those other projects are new ones that I am involved from beginning, no such history issue.
I get it that it's not good to quit the project now.
Also, I should do more to "persuade" B to support me in my performance review.
Thanks.
