Coming from a different field, and not as a business owner, but it sounds like they’re suggesting that you document all of your processes and maintain some kind of knowledge base that you then make readily accessible to your employees and you.

I’ve found that the below is a good starting point for doing that:

• List out all of the tasks you do, don’t worry about covering absolutely everything at this point, just what you can think of.
• Sort those tasks by how frequently you do them (ie daily, weekly, annually, as needed, etc)
• Additionally sort by priority (Paying employees is probably a high priority task)
• Pick a task and start writing up a procedure for how to complete that task. You’ll probably want a list of required info, tools, and other prerequisites at the top of the procedure followed by detailed step by step instructions for completing the task. It might be a good idea to create a template for this.
• Once you’ve written up procedures for all of the tasks on your list, print it off and put it in a binder or several. Make those binders available to everyone who might need to know that info.
• As you think of other tasks, develop new processes, or think of better ways to carry out existing tasks update the document to reflect those changes. It is not and should not be a static document. It should reflect how you actually do things.
• Ensure that everyone is aware of when it changes.
