Haha, this was hilarious to read, mainly because, on some occasions, I've been a cowboy, at least in the context of this post. I like to think it worked pretty well, since, for what we were trying to do, the processes were fighting against us, so I just... did what I considered right technically, regardless of tickets and sprints and who's team should do what.
Whether it was right, I'm not sure, but people have been happy with my work, so that allowed me a bit of leeway.
