Which methodology combines aspects of both SDLC and prototyping?

The methodology that combines aspects of both the Systems Development Life Cycle (SDLC) and prototyping is Rapid Application Development (RAD). RAD is designed to increase the speed of software development while allowing for iterative changes based on user feedback and prototype testing.

In RAD, the emphasis is placed on rapid prototyping, which allows developers to work closely with users to create a functional version of a product quickly. This enables immediate feedback and adjustments, fostering a collaborative and flexible development environment. By incorporating elements of traditional SDLC, such as structured phases, along with the prototyping aspect, RAD effectively aims to reduce development time and respond more readily to user needs.

This combination of methodologies makes RAD particularly suitable for projects where requirements may evolve or are initially unclear. The resulting flexibility allows teams to adapt more easily to change than if they were strictly adhering to a linear SDLC approach.
