Value-Based Pricing and TDD

I first heard about value-based pricing from an accountant who was creating a startup based on the idea. He tells a story about consulting for a family who inherited an estate. Because of the accountant’s extensive knowledge, he was able to give advice that saved the family a million or more. However, he only charged for his time, a couple of hours. To save that amount, the story goes, the family would have been happy to pay more, an amount based on the value of the work rather than the time it took.
