The sickest analogy I have learned recently is documentation as cache by shl. To learn more go to 13 min mark in this video: How to Grow Your Business by Writing: Sahil Lavingia + David Perell

An application first looks for data in the cache. In case of a cache miss, it checks the database.

Documentation should work as a cache in your organisation. Anyone looking for information should look in the relevant documentation, and only when a cache miss happens, in this case, the info being absent in the relevant documentation, the person should go to the stakeholder.

Stakeholder = database. In-person meeting = database access.
