Now here's a question that anyone can answer by observation alone. How is your church growing? Are people coming to the weekend services and then visiting a small group and "sticking" because of the relationships they form there?
Or, is your church growing by small group members reaching out to friends, family and co-workers and into the small groups first?
This seems to be what separates the churches with a small group ministry from the true small group-driven churches out there.
