Description: Iteration is a single development cycle in which a product is improved or refined. This concept is fundamental in various software development methodologies and project management, where continuous improvement is sought through repeated cycles of design, implementation, testing, and review. Each iteration allows teams to assess progress, identify issues, and adjust their approach as necessary. Iteration fosters adaptability and flexibility, enabling teams to respond to changes in requirements or project environments. Additionally, it promotes collaboration and communication among team members, as each iteration cycle typically includes reviews and feedback. In the context of agile methodologies, such as Scrum or Extreme Programming, iteration becomes a central pillar, where incremental product deliveries are made in short periods, thus facilitating the incorporation of improvements and adjustments based on stakeholder feedback. In summary, iteration is an essential process that allows development teams to advance effectively and efficiently, ensuring that the final product meets user expectations and needs.
