Detailed explanation-1: -1. Spiral model is a software development model and is made with features of incremental, waterfall or evolutionary prototyping models. Incremental Model is a software development model where the product is, analyzed, designed, implemented and tested incrementally until the product is finished.
Detailed explanation-2: -In the spiral model, each loop may not result in deliverable software. In the incremental model, every increment actually leads to a deployable increment at the customer site, one of the major differences between the spiral and incremental models. Each loop of the spiral represents a phase of the software process.
Detailed explanation-3: -Advantages of Incremental Model The process is more flexible. It is less costly to make changes in software through the development stage. It is easier to test and debug due to smaller iterations. It is easier to manage risk because risky components are identified and handled during its iteration.
Detailed explanation-4: -As mentioned above that in Spiral Model the execution of the phases i.e., development and testing happens in a sequential manner, so the type of Spiral Model is evolutionary in nature. Waterfall Model is a relatively linear sequential design approach as each phase should be completed in order to reach the next phase.
