In the audio-only version of this informal video hangout from Mark Finnern's departed treehouse, Finnern reflects with Jon Reed of diginomica on what he learned at SAP in the early days of building enterprise tribes. Now a consultant, Finnern explains why companies should be passionate about communities - not just for customers, but for competitive edge. Finnern also makes his case playfulness as a way of energizing companies and breaking down silos. The guys also discuss Finnern's keys to a successful enterprise communities, and where companies run into trouble. They move into the tricky territory of KPIs, and measuring the results of community investments. The podcast closes with Finnern's take on how SAP has handled community - and the SAP Mentors - after his departure.
