Do you want software that works? Get it right the first time every time. Code exactly what is needed by your customer and don't waste time with bugs, errors, and compile issues. Write code that makes you money and doesn't give you support headaches. See how a small team of programmers holds their clients accountable for completely documenting every new feature request and gets top level approval before making any design changes.

If you are stuck in change order hell, this will give you some ammunition to keep your clients in line.
