I'm not a developer, but work as a consultant in a digital agency. I mostly help define what is going to be built, and why. I can relate to what you're saying.

There's no one true way of doing things, but I'm pretty certain doing it in teams is more often than not a wrong way. The mediocrity of the end result is very frustrating indeed. It's as if one and one become 0.5 instead of three.
