G. Critical mass: An “S-shaped diffusion curve ‘takes off’ at about 10-25% adoption, when interpersonal networks become activated so that a critical mass of adopters begins using an innovation.” Once critical mass is achieved, large scale, rapid adoption of the innovation is inevitable. Once the change moves into the Middle Adopters, it becomes unstoppable. All one requires for systemic change is freedom for the visionary minority to differentiate, operate, and build a practicing minority to critical mass (Acts 5:34-39).
 The quote is a selection from David O. Kueker’s Fuller Seminary Doctor of Ministry project submitted in September, 2007, entitled Diagnosis, Dialogue, and Decision: A Threefold Process of Revitalization For the Illinois Great Rivers Conference.
It is shared here in recognition of its 12th Anniversary along with comments to update and provide perspective on the material. The original project was a Training Manual/Study Guide of three Seminars supported by three chapters of research and an Introduction. The material is available for download at www.disciplewalk.com/Resources.html. In 2009 it was provided for purchase as a softcover book entitled Designing Discipleship Systems: Christian Disciple Making For Any Size Church, Any Theology through CreateSpace.com.
