Policy documents
Policy manuals state the requirement
A policy document states a requirement and identifies who owns it, who it applies to, and what exceptions exist. These are the shortest documents per page in the library, deliberately. A policy that runs past five pages usually means procedural detail leaked into it, and that detail belongs in a separate procedure document.
Each policy manual entry here links to any procedures written under it, so you can move from rule to execution without a second search. When a policy is superseded, the entry stays in place with a link to the replacement rather than disappearing.
