The time interval between the project’s beginning and final delivery is substantially reduced because all parts of the system are prototyped and tested simultaneously. It’s a very efficient approach that reduces the complexity of the development process, where the goal is divided into sub-parts and each sub-part is developed individually. In the end, when all individual pieces are properly developed, then the different prototypes are collectively merged into a single final product in their predefined order. This is because developing a prototype from scratch for every iteration of the process can sometimes be very frustrating for the developers.Ĭ) Incremental Prototyping – In this type of incremental Prototyping, the final expected product is broken into different small pieces of prototypes and being developed individually. In comparison to Rapid Throwaway Prototyping, it offers a better approach which saves time as well as effort. In this method, the prototype developed initially is incrementally refined on the basis of customer feedback till it finally gets accepted. Customer feedback helps in preventing unnecessary design faults and hence, the final prototype developed is of better quality. In this method, a developed prototype need not necessarily be a part of the ultimately accepted prototype. This technique offers a useful method of exploring ideas and getting customer feedback for each of them. There are four types of models available: The process continues until the user approves the prototype and finds the working model to be satisfactory. Once the customer figures out the problems, the prototype is further refined to eliminate them. This document is used to build the initial prototype supporting only the basic functionality as desired by the customer. The process starts by interviewing the customers and developing the incomplete high-level paper model. In this process model, the system is partially implemented before or during the analysis phase thereby giving the customers an opportunity to see the product early in the life cycle. In this model, a prototype of the end product is first developed, tested and refined as per customer feedback repeatedly till a final acceptable prototype is achieved which forms the basis for developing the final product. This model is used when the customers do not know the exact project requirements beforehand.
The Prototyping Model is one of the most popularly used Software Development Life Cycle Models (SDLC models). It offers a small scale facsimile of the end product and is used for obtaining customer feedback as described below: Prototyping is defined as the process of developing a working replication of a product or system that has to be engineered.
