Jesse James Garrett interviews Flickr’s Eric Costello (via Pelle Braendgaard):
JJG: Do you have any formal project management tools?
EC: No, we’re not very formal! That can be kind of frustrating for me as an engineer who has to make the UI work. But it’s also what I thrive on, which is solving UI problems. So although we rarely have everything spec-ed out adequately, it’s part of the fun of doing the development, meeting challenges that arise as we start to actually build the UIs we’ve talked about.
