Final answer:
Rapid Application Development (RAD) skips the design phase as it focuses on iterative development and prototyping.
Step-by-step explanation:
Rapid Application Development (RAD) is a software development methodology that emphasizes iterative development and prototyping. It focuses on quickly delivering a working system by skipping traditional waterfall phases such as the analysis, design, and documentation phases. Instead, RAD starts with a basic prototype, and then continuously refines and adds features based on user feedback. So, the answer to your question is 2) Design phase.
