What are the worst false economies (that is ways of saving money that ultimately cost more than they save) prevalent in the software industry and how do you combat them?
Technical Debt

ie "Just do it quickly, we'll refactor later". Firstly because I have yet to see someone engaging in this behaviour actually refactor later. Secondly because doing things the quick way, instead of the good way makes it harder to add future features or resolve future bugs so you end up losing time in the long run.

Sadly, many still think it saves developer cycles to have them do something fast. I guess it's possible, but I have yet to see it in practice.
