Why do membership-based organizations flounder? Almost always, it is because the organization's leaders are either unaware their organization is floundering or are aware but do not know why. This is only logical because, if organizations' leaders knew what was happening and why, they would try to prevent it from floundering.
Why Organization's Fail
Rotary didn't stop developing membership because people were not interested in joining local Rotary clubs. Recent membership metrics have proven that. It stopped growing because Rotary and its member clubs became product oriented instead of member oriented. They marketed the results of the Object of Rotary instead of its value to its member clubs and Rotarians - its customers - those who fund its operations.
