Breaking the Huddle serves on several levels: it is a pretty good distillation of many of InterVarsity's best practices over the past decade in terms of evangelism and growth training--Five Thresholds, leadership cycle, discipleship cycle, prayer and network mapping, apprenticing, mentoring, witnessing communities, etc. It is also a very good evangelism strategy and discipleship book for churches and communities. But besides this there are very insightful little sections throughout concerning wise and effective leadership such as the wonderful little sections on recognizing and seizing upon "God moments" and embracing change.
