It is Price's law, that the square root of the number of employees is doing half the work.
So from that 300 employees, 17 programmers are doing 50% of the work, and out of this, 4 people are doing 25% of the work. So the value distribution looks like this:
4 people 25% of the work (6.25% per employee). Imagine the senior developer, who knows everything, he is a genius, knows stuff, the CEO the
13 employees do 25% of the work (1.92% per employee) These are the other senior developers
The remaining 283 employee is responsible for the 50% of the work (0.17% per employee). These are the "Culture, Media, and Arts Specialist" and the bunch of "Creator Success Lead at Patreon" (WTF is that title even mean???)
So one of those 4 people are doing the same work as 36 other employee. If they leave, well good luck replacing them. Out of 36 you might find someone who is worthy.
I'm seeing the same thing where I work,every single company, the most of the work done comes from a very small group of people.
Being lean means that you have those 17 people who can do 50% of the work. And there are those people, that could be fired on the spot, because they contribute practically nothing to the company. The larger the company it is, the more there are these people. And I actually dont know, how Price's law deals with people who are making negative contribution to the company, but I'm sure there will be many of this. Like a system architect, who decides to implement something stupid, a manager, who agrees to this, and then 30 developers spend a year building something not really working, which has to be constantly maintained by 15 of those 30 employees. So congratulations to the system architect, he just made about 3 million dollars worth of technical debt with some stupid decisions. But this dept is payed at 50% rate unlike regular debt. Or those people who started policing the authors for their content, which lead to people leaving the platform.
