Companies that have too much tribal knowledge obviously do fail. But for a company to run well, some institutional knowledge will be there. And this will be the most subtle and implicit stuff that really isnt feasible to put down on paper. Or even if it is documented, its hard to understand without building alot of context. Even if that context is present in the docs, its not really possible to internalize it without actually seeing things at work.

All that is what takes time to learn and it cant really be eliminated either because thats what is critical for you company to run on
