What does a high functioning CS organization look like?

Hi all,

I have been in both individual contributor roles and leadership roles, mostly with smaller start-ups/scale-ups. One thing I have a hard time defining for myself is what a truly high functioning CS organization looks like. There are so many opinions out there on how to improve things, that I feel the end goal/vision is missing.

When you look at an organisation of for example 100, or 500, or 1000+ people, what do you look for? What are the must-haves? Where do you start defining what you want, or what you are looking for?

Thanks in advance!
