Somewhat offtopic, something that isn't done enough when people are learning to do design and coding, is to analyze failures
I think that's totally on topic. It's part of the learning process. The other thing that isn't taught is how to take that 'bad design' and refactor it to become a good design. Scrapping an entire codebase isn't feasible 100% of the time, but a refactor can breathe new life into a codebase. In order to improve, you must know where it went bad. Plain and simple.
