Other popular articles: They are excellent for designing good human computer interface systems. Prototyping ensures that the end users constantly work with the system and provide a feedback which is incorporated in the prototype to result in a useable system.It might take a while for a system to be built that allows ease of use and needs minimal training for the end user. Typically, online systems, web interfaces have a very high amount of interaction with end users, are best suited for Prototype model.Prototype model should be used when the desired system needs to have a lot of interaction with the end users.Incomplete or inadequate problem analysis. Incomplete application may cause application not to be used as the Prototype models assume that for each category people retain in memory a single specific example (the prototype), and that category members.Practically, this methodology may increase the complexity of the system as scope of the system may expand beyond original plans.Leads to implementing and then repairing way of building systems.Requirements validation, Quick implementation of, incomplete, but Confusing or difficult functions can be identified.Missing functionality can be identified easily.Quicker user feedback is available leading to better solutions.Since in this methodology a working model of the system is provided, the users get a better understanding of the system being developed.Users are actively involved in the development.
