Iterationszyklus

Iterationszyklus, or iteration cycle, is a repeated sequence of activities used to develop, review, and refine a product or process. Each cycle begins with planning and design, proceeds to implementation or prototyping, then includes evaluation, feedback, and adjustment. The cycle is repeated until objectives are met or the product reaches a production state. In software engineering and product development, iterationszyklus is a core concept of iterative and incremental models, including Agile and Scrum, where work is delivered in time-boxed iterations or sprints, each yielding a potentially shippable increment.

Origin and concepts: The idea derives from iterative development, which values learning and adaptation over strict adherence to a fixed plan. The cycle emphasizes early and continuous delivery, stakeholder involvement, and risk reduction by revealing issues early and allowing changes based on real feedback.

Key elements: Typical steps include planning and requirements refinement, design and implementation, testing and validation, and review with feedback. Insights gained in one cycle inform adjustments in the next. Common metrics used to assess performance are velocity, cycle time, defect rates, and customer satisfaction.

Relation to related terms: An iteration cycle is distinct from a release, though several iterations may combine into a single increment. A time-boxed iteration in Agile is often called a sprint, which formalizes duration and scope to maintain focus and predictability.

Applications: Iterationszyklus is used across software and systems engineering, product design, research and development, and other domains that benefit from incremental improvement and rapid learning.
