James Collins shows the distinguishing factors of greatly performing companies from merely good ones after five years of study on leading 28 companies that went from good to great and sustained at least 15 years of great results of cumulative stock returns beating the general stock market by seven times on average.

Readers of the book will be shocked by some of Collins research results, yet, promised exclusive insights of critical concepts that make good companies leap and emerge as great companies for a sustained period of time.
