Design site Core77 recently turned to our friend and partner T.J. Cook, CEO of CauseLabs, for an essay on the mobile money app that we designed and CauseLabs developed. 

In the story, Cook talks about the assumptions that both CauseLabs and IDEO.org challenged while building a financial literacy app for the Chicago nonprofit Moneythink. “Overturning these assumptions turned out to be a vital part of the process of creating something awesome,” Cook wrote. “Had we not searched out for what we didn't know, we would have ended up building the completely wrong thing.” Inspiring stuff, and a great reminder that testing what you think you know, not matter how seemingly obvious, is a key component of human-centered design.
