A prototype can be defined as a representative example of a given category [1]. A prototype model can be viewed as a rudimentary working model of a product or information system, used to test or prove a concept or a process. A prototype of an Information System can be viewed as a draft version of the system that allows stakeholders to explore system features and test the overall system before dedicating resources for the development of the full scale system.

Prototyping is an iterative process. A high level view of the process allows us to identify the following 4 steps that form the crux of the prototyping approach:

1. Identify Content – Based on the needs of the stakeholders, information is gathered about the features that a system should possess.
2. Build Prototype– Using the information, a prototype is then created to gain an understanding of the system.
3. Review Prototype– The prototype is reviewed for errors and flaws and suitability to the stakeholders’ needs. If it does not align with the testing standards, the process is reiterated until a satisfactory model is created.
4. Freeze Design– Once all stakeholders and designers are satisfied, the prototype model is finalized and no new changes are incorporated into the model.
