What aspect of rapid application development primarily contributes to faster system deployment?

The aspect of rapid application development that primarily contributes to faster system deployment is iterative design. This approach emphasizes creating prototypes and refining them through repeated cycles of development and feedback. By using iterative design, developers can quickly produce a working version of the system, gather user feedback, and make necessary adjustments in subsequent iterations. This process allows for quicker incorporation of changes and reduces the time spent on extensive planning or formal documentation prior to development.

As a result, iterative design accelerates the overall development timeline, enabling teams to respond to user needs more efficiently and ultimately leading to a faster deployment of the final system. This flexibility is a key characteristic of rapid application development, distinguishing it from more traditional development methodologies that rely heavily on comprehensive design phases before coding begins.
