The complexity of an error is low because the prototype enables the developer to detect any deficiency early at the process. The complexity of an error increases because of the nature of the model each phase is sequential of the other.Ĭlient have a preview of the system from the "quick design" and the prototype developed early at the of the process.ĭevelopers can refine or add requirements and specification to the system after the prototype is built. Rapid Application Development, Dynamic Systems Development Model, Spiral. Waterfall Model, Prototype Model, Agile software development. Each life cycle is divided into phases where specific objectives are to be met.īoth models have an objective to reduce the development and maintenance cost.īoth models are suitable for short-term program or short-life span system.Ĭlient can only preview the system only after the final version of the software is developed because there is no feed back loop.ĭevelopers encounter a freezing requirement where they are not allow to modify the requirements or specification of the previous phase until the next iteration.
