FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The spiral model combines the idea of iterative development with the systematic, controlled aspects of the waterfall model. This Spiral model is a combination of iterative development process model and sequential linear development model i.e. the waterfall model with a very high emphasis on risk analysis.

Detailed explanation-2: -Spiral model is a combination of the Iterative and Waterfall SDLC models with a significant accent on the risk analysis.

Detailed explanation-3: -Agile Software Development Life Cycle (SDLC) is the combination of both iterative and incremental process models. It focuses on process adaptability and customer satisfaction by rapid delivery of working software product.

Detailed explanation-4: -Requirement gathering: In the waterfall model, the developers gather and determine project requirements once, at the beginning of the process, and build their project tasks on these determinations. In the spiral model, the developers gather requirements at the start of each iteration.

Detailed explanation-5: -Spiral model is a combination of prototype and sequential model or waterfall model. This model uses same phases as the waterfall model and the same order which is separated by planning, risk assessment and building of prototypes and simulations.
