Which Agile framework typically employs iterations of 2-4 weeks?

1. Kanban

2. Scrum

3. RUP (Rational Unified Process)

4. Extreme Programming (XP)

The correct answer is: Scrum

The Agile framework that typically employs iterations of 2-4 weeks is Scrum. Scrum organizes work into fixed-length iterations called sprints, which usually last between two and four weeks. This time-boxing allows teams to deliver increments of the product at regular intervals, facilitating feedback and continuous improvement. The structured nature of Scrum, including predefined roles, events (like daily stand-ups, sprint reviews, and retrospectives), and artifacts (such as product backlogs and sprint backlogs), supports the management of these iterations and helps teams focus on completing work within the set timeframe. In contrast, other frameworks like Kanban do not use time-boxed iterations and instead focus on continuous delivery by managing workflow and allowing work items to be released as soon as they are completed. RUP is more prescriptive and involves phases that do not conform to short iteration cycles in the same way that Scrum does, while Extreme Programming (XP) may have iterations but typically focuses more on engineering practices and may vary in iteration length. Hence, Scrum stands out for its specific use of 2-4 week sprints to facilitate regular delivery and adaptability.
