I'm doing (or at least trying to do) customer development on a B2C startup. Why? Because after a fair bit of product development experience (mostly agile, mostly outside of the startup world) many things about CD resonated strongly with me. For one quick example, the bits about listening to your customers but not necessarily doing what they say are handled with more insight and nuance than most methodologies. This (and Blank's resume) gave the process enough credibility to me for me to attempt to follow it. I don't feel I'm far enough through the process to answer "the most useful aspect" part yet, although I think most of the core process that I've tried has been useful. CD is actually a pretty small process: It doesn't really that many steps, it just takes time and discipline to execute them. The hardest parts for me so far have been (a) getting really crisp on the problem/solution hypothesis (b) approximating customer visits in a B2C environment
