The basic thrust of this book is that public policy problems, which are often highly complex and uncertain, are ultimately grounded and driven by the different stories participants tell about the problem. Therefore, an analysis of the problem that hopes to inform policy making can and ought to borrow from literary criticism and its methods for analyzing stories since the policy problem itself is a collection of stories.
I read this book as preparation for writing my Ph.D. dissertation in public policy, as I am on the lookout for a theoretical and methodological grounding for my research. With the caveat that my committee will have its own input, I am fairly convinced that a narrative analysis is appropriate for my research.
That being said, do not expect that this book will give you all of the information you need to begin a narrative analysis. It is a doorway that only scratches the surface. Essentially, I used it as a test-case--let me see what this approach is all about before I go off and waste my time reading more about this methodology. At times, this book is hard to follow and you're not exactly sure where one step in the author's method ends and the next begins. Of course, drawing heavily as it does from literary analysis, this isn't necessarily a methodological problem as it is a reader's problem in trying to figure out how to do what the author is demonstrating.
With all that, this book and its author are essentially the foundations upon which narrative policy analysis have been built. That's why I started with it. I wasn't sure whether to give it a three or a four. Ultimately, the ideas are a four or five but the presentation and clarity bring the overall performance down to a three. That's not a reflection on the usefulness of the book but a judgment about overall quality and approachability.
