No time is spent on big unknowns
How we structure our work and teams at Basecamp
Jason Fried

Hi Jason,

Where does fit the kind of work that requires user research, some validation of you assumptions with you user base, or usability testing? Does it all always fit in the two weeks beetwen cycles, or you have room for some of this kind of “uncertainties” (or risk diminishing pratices) in the six week time box?
