Document. All. Of. Your. Processes.
A simple diagram will do.
I used to document processes in a Word document. (*gag*)
You know what happened to those Word documents? They went into the digital wasteland of my company's server.
When I started doing simple diagrams I could bring up those visuals with team members to explain the steps and/or modify the process as the business evolved.
Visual flowcharts deliver better clarity than Word documents.
 Documenting your internal processes can actually make your team stronger and better. I think a lot of times companies tend to, whenever I say document, they think of a Word document and it's step one, step two, step three. What actually works better is a visual chart. So it's almost like a flowchart you're gonna put in there of who's responsible for what and the next step in the process.
Whenever you actually put a visual in front of people, it helps them remember it better than just putting it into a Word document. Also, whenever you need to go back and modify that workflow, it's easier to do that in a visual piece rather than a written piece. I have always made sure that whenever I was onboarding a new team member that they had access to those visual workflow documents so that they could do their job better and they knew what was expected of them.
