The knowledge exists — finding it is the problem
The policy is in a document somewhere. The process was explained in a meeting months ago. The answer is in one person's head, and that person is out. The organization knows the answer; the person who needs it cannot reach it.
Scattered knowledge becomes askable
Bring in the documents, policies, how-tos, and internal material your organization already has, and your team can simply ask. The answer comes back in seconds, drawn from your own sources, instead of after an hour of searching and asking around.
