Unit economics helps you manage people

Unit economics shows which processes need to be improved at the moment. In addition, unit economics provides a tool for evaluating business processes through metrics.

All this allows you to formulate requirements for the people who are responsible for the business process. This means that you can manage your staff; you don't just say that a person must have certain skills, but you understand why they must have these particular skills. 

In addition, by understanding what metrics you really need to achieve, you can more accurately formulate requirements when hiring and save money by hiring people without skills that are redundant for you.
