How Amazon Builds Products Backwards

In a fast-growing company with thousands of engineers, teams kept building features and products no one wanted. Engineering was expensive, and failed launches wasted months of effort. The traditional approach — start with technology, then find customers — led to solutions in search of problems.

Bezos needed a process that ensured customer obsession from day one, not as an afterthought. The challenge was cultural: how do you force every team to think about the customer before they get excited about the technology?

Bezos mandated the Working Backwards process: before writing a single line of code, every team must write a press release and FAQ for the finished product. The press release forces clarity about three things: who is the customer, what is the problem, and why does this solution matter?

This isn't a formality — Bezos would reject press releases that were vague, jargon-filled, or didn't clearly articulate the customer benefit. Teams often went through dozens of revisions before getting approval to start building.

Combined with Pre-mortem thinking — where the team imagines the launch has already failed and works backward to identify what went wrong — this process stress-tests ideas before investing engineering resources. The pre-mortem catches risks that optimistic planning misses: "What if the press coverage is negative?" "What if the first version is too slow?" "What if customers don't understand the value?"

This process produced some of the most transformative products in tech history:

• AWS (2006) — started as internal infrastructure, but the press release revealed the real customer: developers everywhere who needed affordable cloud computing
• Kindle (2007) — the press release focused on "every book ever printed, in any language, available in 60 seconds"
• Amazon Prime (2005) — the press release centered on eliminating the #1 barrier to online shopping: shipping costs
• Alexa (2014) — the press release imagined a world where you could talk to your house

The Working Backwards process is still mandatory at Amazon today, over 20 years after it was introduced. It has become one of the most widely copied product development practices in the tech industry.
