"The Decision Book" by Mikael Krogerus and Roman Tschäppeler presents fifty models for strategic thinking, aiming to improve decision-making skills across various aspects of life, from personal growth to understanding others and leading teams. The book, translated and revised, offers concise descriptions and visual diagrams for each model, encouraging readers to engage with the concepts through practical application actively. It emphasises simplifying complexity and providing frameworks for analysing situations rather than offering definitive answers. The authors intend to provide a workbook that guides individuals in structuring their thoughts and making more informed choices.
