In an agile approach, how does iteration differ from a plan-driven approach?

Iteration occurs across activities — requirements and design are developed together rather than separately

Iteration only occurs during the testing phase

Iteration occurs within activities, just as in plan-driven development

There is no iteration — each feature is built once

Correct Answer

Iteration occurs across activities — requirements and design are developed together rather than separately

Explanation

In an agile approach, iteration occurs across activities. Therefore, the requirements and the design are developed together, rather than separately. This is a fundamental contrast with plan-driven development where requirements must be substantially defined before design begins.
