Which methodology is recognized for using gates as part of its approach?

The Rational Unified Process (RUP) is recognized for using gates as part of its approach. This methodology is structured around iterative development and emphasizes delivering software in increments. RUP includes well-defined phases and checkpoints, or "gates," which serve as criteria for assessing the progress of the project and determining whether to proceed to the next phase.

These gates provide critical decision points where stakeholders can evaluate the outcomes of the current phase, ensuring that any necessary adjustments are made before moving forward. This structured approach fosters a clear path for project management and helps identify risks early in the process, ultimately contributing to a more controlled and predictable software development lifecycle.

In contrast, Agile methodologies utilize iterative and incremental development without strict phases or gates; they focus on flexibility and responsiveness to change. The Waterfall methodology follows a linear progression without the iterative elements and does not incorporate gates. Lean focuses on maximizing value by minimizing waste but does not use a gate framework like RUP.
