True. Also it should be the managements'/team leads' role to act as a midiators. It's a waste of time to constantly argue over what is "right" when all proposed solutions are functional.

Should we spend more time flushing out the unknowns? Should we launch ASAP and interate fast? Should we automate the process? Do we have data to back our assumptions?

The "culture fit" is not superficial and I've always been advocate of fire fast if one is culturally unfit because it slows down everyone
