Startups are known for their high productivity - typically which comes from very talented people just getting on with what needs to be done. Its chaos, but in a good way and with strong leadership, you get the best out of everyone.
As the company grows, the board starts to want some more governance and demands things like scaleability in the team, repeatability, predictability, business continuance etc.
The easy solution is to start defining processes to achieve these and slowly you turn your team into a factory. New resources can come in and follow the set processes to deliver the desired outcomes etc.
The hard solution is to define some boundaries - things like security policies, privacy policies, release procedures, issue tracking etc and then provide good leadership to your team who continue to get things done. You then find other ways to measure and report to the board without introducing overheads and processes.
What I've described is very theoretical and 'chaos' and 'factory' are extremes, but I'm really keen to hear how people are dealing with issues like scaleability in the team, repeatability, predictability, business continuance etc without stifling the team?
