For example, how do you guys help each other during work estimation and prioritization. How often do you sync up and having diagreement? How do you resolve it? Specifically, I am curious if there is a case where SWE team believes that TPM did not make the right decision about product and tries to course-correct.

Interested because I have been promoted to tech lead of my team recently. I want to make sure that I can build good work relationship with my TPM. Feel free to add any advice based on your good/bad real world experience.

Thanks!
