Jim Collins starts out with this book by explaining how he conducted his extensive research with his team to find companies who've sustained at least 3 times the market of cumulative returns over the course of 15 or more years. After they found 11, they compared each company to a direct comparison to figure out what the great companies did to make the "leap" that the good direct companies didn't.
The book was broken down into 6 main points where the first 3 were to build up and set the foundation of the company through Level 5 Leadership, choosing the right people, and Confronting the Brutal Facts while accepting them and never giving up. The next 3 explained the breakthroughs of the companies by using the Hedgehog Concept, Culture of Discipline, and Technology Accelerators.
Collins does a great job relating to the readers by using examples to explain his concepts. For example, he named a chapter "The Hedgehog Concept" and explained how great companies focused all challenges and dilemmas into simple ideas, instead of branching out into different, complex principles. He also makes use of graphs and diagrams to help his readers understand and visualize points he is trying to make.
Overall, Jim Collins writes an enjoyable book that even students can comprehend, yet CEOs can use to benefit their company.
