How policies are written
Writing policies is a difficult task, they cannot be too specific or too broad, must be consistent and clear, and enforceable in some way. Not everything warrants a policy, in fact the less policies you have the better. The best policies are valid for a long period of time and need little to no amendments. It is always good to start with the purpose of the policy (why), followed by possible implementation paths (how) and examples of how it will affect the organization (what). Pictured below is the Golden Circle from Simon Sinek. For a more formal approach to writing policies, check out this document.
