Which method combines approaches like incremental and waterfall into a hybrid model for software development?

The hybrid model that combines approaches like incremental and waterfall is known as the Spiral model. This method integrates the iterative nature of incremental development with the structured approach of the Waterfall model. The Spiral model emphasizes risk assessment and refining the software through repeated cycles, or "spirals," which allow for continuous development and feedback. This means it can adapt to changes more readily than the traditional Waterfall model, making it particularly useful for complex projects where requirements may evolve.

The Spiral approach consists of four main phases: planning, risk analysis, engineering, and evaluation. Each iteration involves revisiting these phases, allowing teams to incorporate user feedback and improve the product progressively while also managing risks effectively. This combination of systematic planning and iterative development is what sets the Spiral model apart and makes it advantageous for software projects that require flexibility and responsiveness to changing requirements.
