Everyone talks about common business mistakes like poor cash flow or bad marketing, but I think a subtler one is over-relying on a single "star" employee. I've seen small companies grind to a halt when that person leaves, taking all the institutional knowledge with them. How do you build systems that make your business resilient to any one person's departure?
That star employee risk is real and the cure is to systematize knowledge and remove reliance on one person.
Set up standard operating procedures for critical tasks and store them in a central knowledge base so others can pick up quickly.
