I was assigned this book as part of a doctoral class on understanding problems in ministry and the systemic forces that cause them. Halstead writes to ministry leaders to help them deal with problems that hold their organizations captive and from which they cannot get "unstuck." Within the pages are some very good and useful insights. The problem is that these few good and useful insights are hidden within 172 pages of every "if-then" scenario one can imagine. Rather than helping the reader how to think in systems, it felt as if the pages were covered with "if this problem happens, then respond this way, but if this other problem happens, then respond this way."
For those of us who want to focus more on moving people toward a vision rather than constantly dealing with problems, this book was draining. There are other books that deal with systems that are much better (Senge's The Fifth Discipline). Avoid this one unless you enjoy searching for a few pieces of gold among mountains of copper.
