ABSTRACT
Communities are groups of people that work together toward a common purpose. Their ability to do so, of course, depends on how strongly they see their common purpose, and how effectively they can coordinate their resources against that common purpose. In more than 100 improvement projects within corporate research and development (R&D), some things have emerged in the study of groups in their ability to overcome technical and scientific hurdles over years of effort that, if we are lucky, will yield a new pharmaceutical treatment.
