Which approach emphasizes user feedback during system design?

The approach that emphasizes user feedback during system design is Joint Application Development (JAD). This technique involves collaborative workshops attended by various stakeholders, including end-users and developers, to gather requirements and develop systems more effectively.

In JAD sessions, participants can interact, voice their needs, and provide instant feedback on the system design and functionalities. This ensures that the final product aligns with user expectations and improves overall satisfaction. The format of JAD encourages comprehensive discussions and the exploration of ideas, which can lead to innovative solutions and a deeper understanding of user requirements.

While other methodologies like Rapid Application Development (RAD) and Prototyping also incorporate user feedback, JAD particularly stands out due to its structured, collaborative nature. The Systems Development Life Cycle (SDLC), on the other hand, typically follows a linear sequence of phases, which may limit the ongoing engagement of users throughout the entire design process.
