What is iteration in product development?
Iteration in product development is one cycle of building, measuring and learning — designing a feature, releasing it, observing its impact, and feeding insights into the next cycle. Iteration is central to Agile and Lean Startup methodologies.
Iteration speed (cycle time) is a key competitive variable: companies that can run more learning cycles per quarter outpace competitors. Iteration discipline is paired with feature-flag systems, A/B testing infrastructure, and clear hypotheses.
