Which model is known for providing the theoretical basis for other Software Development Life Cycle (SDLC) models?

Waterfall Model
Incremental Model
Spiral Model
Prototyping Model

The correct answer is: Waterfall Model

The Waterfall Model is recognized as the foundational model that has influenced various other Software Development Life Cycle (SDLC) models. This model follows a sequential design process, where each phase must be completed before moving on to the next. This linear sequence provides clarity and structured phases, such as requirements analysis, design, implementation, testing, deployment, and maintenance. The significance of the Waterfall Model lies in its simplicity and ease of understanding, which allows it to serve as a basis for more complex models. Many subsequent methodologies, such as the Spiral Model or Incremental Model, incorporate elements of the Waterfall approach while introducing iterative processes or risk management components. Essentially, the Waterfall Model sets the stage for the development of various agile and iterative methodologies, underscoring its role as a pivotal framework in the evolution of software development practices.
