Founders, are you doing customer development? Why or why not?
For those who are, what have you found to be the most useful aspect of it? The hardest?
I ask because it seems like the HN and lean startup communities don't overlap that much and I'm curious why.
I did a PhD in embedded computer systems design which described "realistic" methods for designing new products with small teams through intense engagement with your future users. This was in an academic setting though, and I'd been wondering how to "sell" the idea of participatory design in much the same way user-centred design had been to companies as an alternative to traditional design methods.
Then I read Steve Blank's customer development strategies. Beaten to the punch. So I'm curious - is Steve aware of PD? What inspired CD?
Anyway, to answer the OP - working as an external designer/developer for a small dental firm, I found that our approach, which was very similar to CD in a lot of ways, was very useful for learning what truly mattered to the customer. You are able to cut away the cruft from the design process very quickly. It's hard to tell what people want by watching them, it's hard to tell what they want by having them tell you, but it's easy when you collaborate with them in the design process.
The hardest part is it takes up a lot of time, but when you're establishing a toe-hold in the market, that's ok, and it's a differentiator for your company. We made a lot of people very happy by fulfilling their needs really well.
