A client needed a software application to be delivered with a demo of the working software at every stage of development. The project head ensured that all the team members were in the same location. The work was completed in a short duration with minimal documentation and through continuous customer interaction. Which model did the team use? A agile B. spiral C waterfall D. RAD ​

Rapid Application Development (RAD)

Explanation:

Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.

RAD is an acronym for rapid application development and it is a model that is typically based on the concepts of prototyping and iterative development technique with minimal documentation or planning involved.

In the RAD model, more priority is given to the development of the software while minimal attention is given to documentation or planning. Therefore, it focuses on developing softwares within a short period of time and using prototypes (working modules) such as templates, codes, processes, tools, etc.

Basically, the RAD model comprises of five (5) phases and these includes;

I. Business modeling.

II. Data modeling.

III. Process modeling.

IV. Application generation.

V. Testing and turnover.

In conclusion, the RAD model allows software application to be delivered with a demo of the working software at every stage of development for continuous customer interaction.
