This panel will discuss specific failures that faculty have encountered while working in sustainability, social entrepreneurship and humanitarian engineering programs abroad. This is partly a follow-up to the NCIIA 2010 conference talk titled "Preparing Students to Travel Overseas: Experiences from MIT's D-Lab". A discussion started during the talk about how rarely, and with good reasons, people discuss their failures. This talk will help "advance the field of invention, innovation, and entrepreneurship education" by giving real world examples of failures and lessons that can be learned for future projects. We hope that, by exposing past errors, participants can move on to new ones and continue to become more effective.
