We develop software iteratively and incrementally. That means we're constantly making small changes, improvements, and adding new features; and that we get those changes in front of real users as fast as possible. It's only but seeing how users use our software that we can get the best feedback about what to change, and what features to build next. It is a cycle: plan, build, deploy, learn, plan.
The shorter the cycle, the more easily we can cope with sudden or unexpected changes in business needs or user behavior. It gives us a chance to constantly validate our assumptions.
