A company needs structure and processes if it wants to become an environment in which people want to work productively. When a company grows from 2 people to maybe 7, you have to start thinking about management structures, processes and first rules that everybody needs to apply.

When a company grows beyond 7, these problems starts to become more and more complex. You need more structures and more rules. BUT! How can you manage the growth of a company without using old traditional models?

Ed Cutmull [1] wrote, that it is the job of a manager to make sure that the organization will survive in case of failures. So, there is the notion of stability in being a manager.

E.g. a friend of mine, Boris, has a small company and he started last year in autumn with these kind of questions:

What is the best structure for his small company? What is his position and his role within his company? Given the fact that he is doing the work as a job, and running a company as a manager. I am 100% sure we will see a lot of change in his small company over the next months. [tbc]
