Alan Harrison is a writer, father, performer, consultant, recovering artist, and the author of the industry best-seller “Scene Change: Why Today’s Nonprofit Arts Organizations Have to Stop Producing Art and Start Producing Impact, “Scene Change 2: The Five REAL Responsibilities of Nonprofit Arts Boards,” and his latest and last of the trilogy, “Scene Change 3: The Ones Who Get It.” For 30 years, he has led, produced, directed, promoted, raised money for, starred and failed in over 300 theatrical productions on and Off-Broadway and at prestigious (and not so prestigious) nonprofit arts organizations across the country. He’s also a two-time “Jeopardy!” champion so, you know, there’s that. The arts invoke passion (mostly from artists), but nonprofit arts are only successful when they result in measurably positive change among those that need it most. When a nonprofit’s donors are also its recipients, then its mission devolves into meaningless puffery, flapdoodle, and codswallop.
