In my experience, tribal knowledge, which also includes cultural inculcation, can be the difference between success and failure. Sometimes, on the success side, and, sometimes, on the failure side.
The main thing about "tribal knowledge," is that it relies on long-term association/employment, and that is not something we see much of, these days.
Surely there are tribes that transcend and cross corporations. That's why you can hire old colleagues and get a team up and running in a startup or new firm
