Which of the following methodology is/are iterative?Question 3Select one:a.UPb.XPc.Scrumd.All of the above

To determine which methodologies are iterative, let’s evaluate each option:

1. Waterfall (U) Methodology: This is a linear approach where each phase must be completed before the next one begins. It is not iterative.

2. XP (Extreme Programming): This is an Agile development methodology that emphasizes customer satisfaction and flexibility. XP incorporates iterative practices, allowing for continuous feedback and adaptation.

3. Scrum: This is another Agile framework that promotes iterative progress through sprints, which are time-boxed cycles of work.

Based on this analysis:

• A (U): Not iterative.
• B (XP): Iterative.
• C (Scrum): Iterative.
• D (All of the above): Incorrect since not all are iterative.

Final Answer

B and C are the iterative methodologies; therefore, the correct choice is: B (XP) and C (Scrum).
