After five years of research, Jim Collins, author of the best-seller Built to Last, put his team’s hard work into his insightful book Good to Great. Starting with the question, ‘Can a good company become a great one?’ Collins and his team came up with eight factors that take an organisation from good to great. By examining 11 ‘good to great’ companies, Collins demonstrates exactly what it takes for an organisation to level up. Every one of the 11 companies demonstrated all of the 8 factors discovered by Collins and his team, but what’s interesting is that they can be applied to anyone at any time, whether you are looking to guide others or excel at school. There are so many parallels between business and life, which is why this book is an essential read for all ages. In this summary, I have explained each business lesson and shared how it can be applied to students and teachers.
