Warren Bird and I were interviewed at Leadership Network about our new book, Viral Churches. Here's an excerpt of the interview where I explain a little of the background to the book.

Over a six month period, with twenty-four interviewers, we surveyed hundreds and hundreds of people from denominations, networks and churches to ask questions about what is working in church planting.

...

We tried to create a standard for measuring a church multiplication movement. We define it as when a movement of churches has a 50% reproduction rate each year with 50% of the people coming to the new churches as new converts and then seeing that pattern through the third year. In other words, if one year there were 100 churches, the next year there'd be 150 churches and half of the new people in those churches would be new converts and that goes on for at least three years. We consider that to be a church multiplication movement.
