We've tried to institute technical design docs and reviews and failed. Management keeps asking we do them but doesn't enforce it. Developers don't want to do it and take it personally when you suggest a different approach during the review. Management sets deadlines on projects without consulting leads or architects. I (database architect) have suggested we add steps for technical approval and code reviews to our feature/bug tracking system but have been ignored. I'm sure people can relate out there.
