“Good to Great: Why Some Companies Make the Leap…And Others Don’t” by Jim Collins is a seminal work in the realm of business literature, exploring the factors that differentiate truly great companies from their merely good counterparts. Collins and his research team conducted a rigorous five-year study to identify companies that made a sustained transition from mediocrity to greatness and, importantly, sustained that greatness for at least 15 years. The book introduces the concept of Level 5 leadership, emphasizing the importance of leaders who blend personal humility with professional will. Collins identifies key principles, such as getting the right people on the bus and in the right seats, confronting the brutal facts of reality, and maintaining an unwavering commitment to a core ideology, as critical components of the transformation process.
