So, I learned. I learned from interviewing the customers, I learned from the senior members of the development team, I learned from books. I wrote a bunch of code to automate certain processes.

And it turned out… some of those processes didn't make sense. They weren't repeatable; they didn't actually make sense. At one point, I had an argument which was almost *exactly* the famous bodybuilding forum "how many days are in a week" thread. With a customer who owned a $30MM business.
