The Bus Factor
The Bus Factor, as defined by Wikipedia:
A software project’s bus factor is a measurement of concentration of information in a single person, or very few people. The bus factor is the total number of key developers who would if incapacitated, as by getting hit by a bus, send the project into such disarray that it would not be able to proceed.
How would your company do without you if you became sick for a month? Six months? Quit completely? Or put the other way, if you want to quit, can you get out without leaving a complete mess behind you?
If you’re an entrepreneur, this is even more important. Especially if you’re looking into one day selling your company. Nobody wants to buy a company which is worthless without the seller.
What is the bus factor on your project or company?
