Book excerpt: "This book provides a tools-based approach to strategic management. The central framework rests on three pillars that constitute the essence of strategy, namely: to diagnose, to decide, and to deliver. Within this framework a suite of strategic management tools is offered, which include both the classics and the more nascent frameworks used to strategize. The first part of the book offers a brief introduction to the essentials of strategic management, and unpacks the "3D" framework of strategy. The second part of the book revolves around explaining the purpose, underlying theory, core idea, depiction, process, value created, risks and limitations of each tool. Concrete hands-on advice is emphasized. The book also offers case illustrations here that offer concrete examples of how the tools can be applied. The concluding chapter summarizes the key insights on a high level and offers concluding thoughts on how the tools can be combined"--
