I would highly recommend the book, Nudge.  It provides a blueprint for building behavioral architects.  Simply put, it can help one understand the choices that make one program work brilliantly and another fail.  These micro-adjustments are often traced back to behavioral tipping points.  I appreciate the authors’ ability to breakdown complex behavioral concepts into the notion of the Planner (best represented by Mr. Spock from Star Trek) and the Doer (seen in the styling of Homer Simpson).  When you consider the little nudges a social enterprise can utilize to standout in a crowded sector, the book is a highly valuable resource.
