“Lean Coffee” is an informal networking and discussion group, a gathering for San Antonio healthcare folks that has been held in June and September 2014 and again in February and April 2015. The intent is to hold this event on a quarterly basis. Discussion groups are limited to ten people and it's not necessarily the same people each time.
It's a great format that I learned from Jim Benson. You use a “personal kanban” board (the table, really) to solicit discussion topics from the attendees. Then, we vote on what to discuss and we decide, as a group, and when the topic has been exhausted, we move on.
