A standard operating procedure (SOP) is something I’ve been asked to communicate a number of times. Usually the SOP is already written, but needs further communicating as people don’t seem to be following what it says. It sometimes turns out that further communication is an issue, but not the only issue.
An SOP is supposed to achieve consistent results by consistency of action. It isn’t just about a prescribed process; it can also include a basis for assessment such as a decision tree. The whole SOP should work as a flowchart with identifiable stages, logical procedures, and clear rationale for decision points.
