Policy vs Procedure vs Work Instruction: What├ö├Â┬úÔö£├é├ö├Â┬úÔö£┬║├ö├Â┬úÔö£Ôòùs the Difference?

A policy answers the question ├ö├Â┬úÔö£├é├ö├Â┬úÔö£┬║£what does this business commit to?├ö├Â┬úÔö£├é├ö├Â┬úÔö£┬║├ö├Â┬úÔö£ÔöÉ rather than describing how that commitment is delivered day to day. It is typically short, high-level, and reviewed periodically rather than for every operational change.

A procedure sits below the policy and describes a process in enough detail that someone unfamiliar with it could understand who does what, in what order, and what records the process produces. Procedures are where accountability and sequence live.

A work instruction is the most detailed level, focused on a single task, and is most valuable where precise, repeatable steps genuinely matter - operating a specific piece of equipment, carrying out a specific inspection, or following a specific safety-critical sequence.

Proportionality is the key principle across all three levels. A small business with simple, low-risk activities may only need policies and procedures, while a business with more complex or higher-risk operations benefits from detailed work instructions as well. Documentation that exceeds what a business genuinely needs becomes a burden rather than a control.

A frequent, avoidable mistake is writing detailed work instructions without involving the people who actually do the task. A work instruction written from a desk, without input from the person carrying out the work, often does not reflect how the task is genuinely performed, and is quietly ignored in practice as a result.
