Iteration is the process of repeating a set of actions or steps to achieve a desired outcome, often with incremental improvements. It involves cycles of planning, executing, and evaluating work, allowing for adjustments based on feedback or new information. This cyclical approach is fundamental to agile methodologies, enabling teams to adapt quickly to changing requirements and deliver value incrementally. For example, a software development team might iterate on a feature by building a basic version, testing it with users, and then refining it based on their input. Unlike a linear, one-time approach, iteration embraces continuous refinement and learning throughout a project's lifecycle. This concept is frequently encountered in project management certifications like PMP and CAPM, as well as agile focused exams such as PMI-ACP.
