Generally Spiral Model strategy is followed for the large and complicated projects where risks are high and development and testing goes on incremental basis. What are advantages and disadvantages of spiral model? What is Spiral Model in software testing and what are advantages and disadvantages of Spiral Model. Flexibility: Any feedback from the client that results in changes to be made to the system can be easily adopted and implemented. While one is stuck between the waterfall model vs spiral model debate, it is best to evaluate the software that is being developed and then decide the right approach. Based on the client evaluation, the software development method enters the next iteration and consequently follows the direct approach to complete the feedback recommended by the customer. • Users see the system early.
