Seeing my company fail at software engineering -- we created a huge messy system that was barely ever refactored while the list of features piled up uncontrollably and the team grew -- i would like to know how others do it.

I've already read "The Mythical Man-Month", "The Phoenix Project" to learn some useful lessons on how to successfully build software. Maybe there are other books you guys know, possibly with real world stories of successes to learn from? I would like to suggest specific steps to my leadership so I'm looking for any information on the topic.
