The person who writes the process owns it. Your name goes on this.
An SOP — Standard Operating Procedure — is a written record of how to do a recurring task correctly, every time, without re-figuring it out from scratch.
This template walks you through what an SOP is, why it matters from day one of any job, a complete worked example (closing shift procedure), and a blank ten-section template you fill in for any task at any job.
You don't need to be in a big company to do this. You need one recurring task that nobody has documented yet.
