I'm literally dealing with that as we speak. Some architecture developed by the Staff Eng. on a team that's really not workable and was causing the team to run in circles. Ultimately, I had to jump in and ask a lot of questions about the implementation. i.e. Why was it built that way, along with the related questions about what goals of the implementation were (elegance, speed to delivery, future-proofing, ability to parallelize code effort, etc) and what app/business problems the code was solving.
