Frugality and the Lean Culture

Tucked into the decision-making list is a commitment to spend wisely and maintain a lean culture, with a pointed reason: cost-consciousness matters especially in a business incurring net losses.

This is the counterweight to bold bets. Amazon invested aggressively in the things that compound (customers, infrastructure, selection) and stayed cheap on everything else. The famous door desks came from this. Frugality wasn't poverty, it was allocation discipline.

The letter also promises to measure programs analytically, jettison the ones without acceptable returns, and double down on what works. Frugality plus measurement is the whole system: big swings, funded by ruthlessness about everything that isn't working.
