I've never worked anywhere in 18 years where the goals of a project weren't at least limited to the correct 'vehicle class'. Implementation details sure can change but that's why "fast and disciplined" is good - you learn to implement the software in a manner where you understand the changes needed based on concrete principles rather than a mad dash of copy-and-pasting. By 'disciplined' I don't mean that the program fullfills the dogmatic mandates of some system development philosophy - just that the software is written on solid principles that at least the author understands.
