The decision-making philosophy that built Amazon into a $1.7T company — Two-Way Door decisions, Working Backwards, Day 1 mindset, and long-term thinking. Documented across 25 years of shareholder letters, with concrete applications for founders and managers.
Working Backwards is Amazon's product development methodology that starts with the desired customer outcome — written as a press release announcing the finished product — before any engineering begins. Championed by Jeff Bezos, it forces precise articulation of customer value and the product experience before committing resources, reversing the natural tendency to build first and then figure out why customers should care.
