Journalist Mikael Krogerus and communications expert Roman Tschäppeler summarize 50 of the most popular decision-making models that individuals and businesses around the world adopt and use to make significant choices and to think in a strategic way. The authors’ thoughtful little book shows readers how to develop a strategy, how to choose among alternatives and how to make intelligent decisions.
