Decide the outcome you want for your business (and your role in it). If you don’t have a destination, any road will get you there.
Break down the business into the categories that need to be systematized. Functional areas work well (Sales, Finance, HR, etc).
It’s important at this stage to just decide WHAT needs to be accomplished, not HOW. Too often CEOs jump to how, without assessing if they have the right WHAT.
Now you know what must be true to get to your goal (say $6M top-line). Before jumping to HOW, for each area you assess where you are.
