Which type of systems development speeds up the design phase and intensively involves users?

The correct choice emphasizes the importance of Joint Application Development (JAD) in systems development, particularly in enhancing the design phase and fostering user involvement. JAD is a structured process that brings together users and developers in a series of focused workshops to gather requirements and define system features collaboratively. This approach significantly accelerates the design phase because it emphasizes direct communication and collaboration among stakeholders.

During JAD sessions, users provide immediate feedback, which helps developers understand their needs more clearly and make necessary adjustments in real time. This direct involvement not only speeds up the design process but also ensures that the final product is more aligned with user expectations, reducing the potential for miscommunication and rework later in the development lifecycle. As a result, the systems developed through JAD tend to have higher user satisfaction and are more likely to meet organizational goals.

Understanding this methodology highlights its effectiveness compared to other approaches, which may not emphasize user involvement to the same extent or may stretch the design phase over a longer period without the concentrated input that JAD promotes.
