Microsoft Humanitarian Systems (MHS) is an expeditionary team under Microsoft Chief Software Architect Ray Ozzie, tasked with investigating and building working models of advanced solutions to address collaborative aspects of some of the most vexing, emotionally-charged, and least-served human interaction problems, including relief, development, conflict resolution, human trafficking, and human rights. The team is founded on the premise that significant, forward-looking collaborative solutions can emerge when they are designed for - and developed in - complex environments where networks are unreliable, equipment fails, trust is lacking, training is minimal, users are highly mobile, and information overload is the norm.
