What is spiral model advantages, disadvantages and when. It is difficult to divide the software and the problems in several versions that would be acceptable to the customer which can be implemented and delivered incrementally. The following are the advantages of the prototyping model. Then thereafter many successive iterations versions are implemented and delivered to the customer until the desired system is released. Alas, no project development model is perfect expect for, perhaps, oxygen plus hydrogen equals water. The spiral model is similar to the incremental model, with more emphasis placed on risk analysis. Evolutionary model helps to accurately elicit user requirements during the delivery of different versions of the software.
