Just so you know, this is often referred to as the “Bus Factor”, aka “how many employees would need to get hit by a bus for us to suffer a catastrophic loss of knowledge/manpower?” Way too many places have a bus factor of 1, meaning if that single employee isn’t available for whatever reason, everything around them grinds to a halt. You usually want that number to be BIG as often as possible.
