The book deals with the economic and social mystery of the entities that underpin communities. It provides an overview of the prevalence and value of small firms to economies around the world; continues with a focus on the motivations for business ownership; and discusses the lifecycles of small firms. The book considers each tribe in detail alongside a discussion of the research relevant to the issues they confront.

The book argues that taxonomy through a case-based approach to deepen the understanding of the issues identified within each tribe and how it impacts on their capacity to achieve business goals and aspirations.
