For the past thirty-five years, the success of this work, a true strategy bible, a leader in France and in many French speaking countries, and now translated into English for the first time, has never waned.

This latest edition has been revamped by a small team of professors, with a dual purpose in mind:

• Firstly, to deliver a concise and cohesive textbook suitable for Master’s and MBA students in both university and business school settings, as well as for consultants and company executives, whether in active roles or undergoing training. This textbook serves as a practical handbook for addressing case studies in both academic and real-world contexts.
• Secondly, our aim is to establish a comprehensive ‘strategy encyclopedia’, facilitating a thorough exploration and critical analysis of the various approaches, theories, and concepts that underpin strategic thought and practice.

This English adaptation of the 9th French edition offers recent examples from all industries. It focuses on the current changes in the business environment, particularly those of digital strategies, artificial intelligence, innovation, leadership, globalization/de-globalization, as well as corporate social responsibility.
