What user-oriented method resembles a condensed version of the entire SDLC with user involvement every step of the way?

The correct answer is Rapid Application Development (RAD). This method is characterized by its focus on user involvement throughout the development process, enabling stakeholders to provide feedback and input continuously. RAD emphasizes quick iterations and prototypes that allow users to visualize and test parts of the system as it develops. This leads to a more user-centric design that can better meet the needs of the end-users.

In RAD, the stages of the software development lifecycle are condensed, allowing for faster development cycles while still ensuring that users have a significant influence on the product being created. This method pushes for the collaborative creation of functional prototypes, which can be refined based on ongoing user feedback.

Other methodologies like Joint Application Development (JAD) focus more extensively on workshops and meetings to gather requirements rather than continuous user involvement throughout a project. Agile methodology, while also user-driven, typically allows for flexibility in scope and functionality rather than focusing on rapid development as a primary goal. Incremental development, on the other hand, breaks down the system into smaller, manageable parts which are delivered over time but may not emphasize prototyping and user feedback in each cycle to the same degree as RAD does.
