System mapping is a set of tools with different capabilities. Seven tools are described in the book, including causal loop diagrams (CLD), system dynamic (SD), theory of change (ToC), fuzzy cognitive mapping (FCM), and Bayesian belief network (BNN). It covers various data collection and analysis techniques for action research and facilitation. This book provides information about the typology of system mapping, an explanation of how to use them, the advantages/disadvantages, and a brief history of their development.
The authors seem to avoid lengthy discussions about the theoretical background of the tools. They guide the readers directly to be familiar with the implementation and to be able to select one or combined tools to serve specific purposes. Although some confusions remain. First, why are these tools selected among others? Second, the names of each instrument are often used interchangeably, meaning that they are somewhat relied on each other such as CLD and SD. Overall, this book is application-oriented.
