incrementally

This term describes a process of gradual growth or change through a series of small, discrete steps. It is frequently used in technical, scientific, and business contexts to describe a strategy of cautious improvement or a phased rollout, contrasting with a "big bang" approach where everything changes simultaneously.

In software development and project management, it carries a connotation of risk mitigation. By implementing changes incrementally, developers can test and validate each small addition before proceeding, ensuring that errors are caught early and the system remains stable throughout the evolution.
