There are certain parameters that have an impact on the overall value of your business. We call them value drivers. The most critical one has to do with how important you are to the success of your company. In a nutshell, the more essential you are to the success of your company, the less it is worth to someone else.
There are many value drivers, but in our opinion the most important one is having a business that can run without you. Make yourself operationally irrelevant to your business and you will have gone a long way towards maximizing its value.
