Amazon's "Day 1" mentality is a culture and an operating model that puts customers at the center of everything Amazon does. Putting "Day 1" into practice relies on maintaining a long-term focus, obsessing over customers, and bold innovation.
As an example, at AWS, around 90% of the features developed come directly from hearing about what their customers need. The other 10% comes from being close enough to customers where they can invent on their behalf when they don’t, or can’t, articulate those needs.
