The Decision Book: Fifty Models for Strategic Thinking

The Decision Book is a popular book by Mikael Krogerus (journalist) and Roman Tschäppeler (communications expert). It has become an international bestseller because it presents the most useful tools for decision-making in a simple and clear way.

The book is not theoretical, but a practical manual that explains, illustrates and demonstrates the application of fifty proven frameworks in a few pages per model. The models are divided into four main categories:

• How to get to know yourself better (e.g. Johari Window, Maslow Pyramid, Personal Potential Trap)
• How to get to know others better and improve relationships
• How to make decisions (Eisenhower Matrix, SWOT Analysis, Rubber Band Model)
• How to develop a strategy and solve complex problems (BCG Matrix, Long Tail, Prisoner’s Dilemma, Conflict Resolution, etc.)

Each model is presented visually – in diagrams, tables or simple schemes – which facilitates quick understanding and application. The authors emphasize that it is not necessary to use all the tools, but to choose the one that best suits the situation. The book helps with everyday choices (what to eat for lunch) as well as with serious business or life dilemmas (changing careers, resolving conflicts, evaluating a business idea).

It is ideal for managers, entrepreneurs, students, and anyone who wants to think in a structured way and make better decisions. It does not delve deeply into the psychology of each model, but rather provides a clear overview and encouragement for further research. Stylishly and compactly arranged, The Decision Book is the perfect “tool in your pocket” – a book you will often leaf through instead of reading from cover to cover.
