In agile and iterative development, which practice is used to deliver usable functionality in small increments?

• A. Iterative Development
• B. Waterfall
• C. Gantt Chart
• D. Risk Register

Answer: (A)

Iterative development delivers usable functionality in small, short cycles. In each iteration, a working piece of the product is produced that provides value and can be shown to users for feedback. This enables rapid learning, frequent validation, and the ability to adjust direction based on real input, which keeps the product aligned with needs as it evolves. Waterfall follows a linear sequence with a single final release, making it hard to incorporate feedback early. A Gantt chart is a planning tool for scheduling tasks and timelines, not a method for delivering increments of functionality. A Risk Register tracks potential problems and responses, not the actual development approach for incremental delivery.
