The Decision Book: Fifty Models for Strategic Thinking

The Decision Book functions as a structured visual encyclopedia of fifty established mental frameworks used in business and psychology. Authors Mikael Krogerus and Roman Tschäppeler condense complex organizational theories into one-page summaries paired with minimalist diagrams. The content is organized into four distinct quadrants: how to improve yourself, how to understand yourself better, how to improve others, and how to improve tasks. Within these sections, the book presents practical tools such as the Eisenhower Matrix for time management, the SWOT analysis for evaluating corporate positions, and the Prisoners’ Dilemma for calculating strategic incentives.

This manual serves professionals, project managers, and students who require immediate, actionable logic for problem-solving. Readers use these models to categorize information and remove emotional bias from their professional choices. By studying these frameworks, an individual gains a versatile toolkit for navigating office politics, refining personal productivity, and building more efficient workflows. The reader finishes the book with a repertoire of mental shortcuts designed to clarify complex situations and facilitate faster, data-driven conclusions in high-pressure environments.
