When you build software for a client that is a completely different game. I divide this into two completely separate areas: * advisory -- you advise your client on what is prudent in their circumstances, * software development -- you produce software to client specifications, regardless of what they asked. You can advise them all you want but then you do what they asked and that's it -- they are always right.
