In 2018 Amazon became the world's second trillion dollar company after Apple: a remarkable success story for a company launched out of a garage in 1994. How did they achieve this? And how can others learn from this extraordinary success and replicate it? Colin started at Amazon in 1998; Bill joined in 1999. Their time at Amazon covered a period of unmatched innovation that brought products and services including Kindle, Amazon Prime, Amazon Echo and Alexa, and Amazon Web Services to life. Through the story of these innovations they reveal and codify the principles and practices that have driven the success of one of the most extraordinary companies the world has ever known, from the famous 14-leadership principles, the bar raiser hiring process, and Amazon's founding characteristics: customer obsession, long-term thinking, eagerness to invent, and operational excellence. Through their wealth of experience they offer unprecedented access to the Amazon way as it was refined, articulated, and proven to be repeatable, scalable, and adaptable. Working Backwards shows how success is not achieved by the genius of any single leader, but rather through commitment to and execution of a set of well-defined, rigorously-executed principles and practices that you can apply at your own company, no matter the size.
