A prototype is a mockup or can also be defined as electronic ‘picture’. It allows the stakeholders to interact with an envisioned product, gain experience in realistic setting and explore imagined uses. A prototype is a limited representation.
By prototyping, it gives aids when discussing ideas with stakeholders. It is a communication device among team members as well as an effective ways to test ideas. It clarifies vague requirements.
There are two types of prototypes; Low-Fidelity and High-Fidelity. Low fidelity prototypes do not look very much like the real final product. The materials used are often very different from the final product. This type of prototyping is cheap and quick to produce. It supports the exploration of alternative ideas/designs. Besides, it is important during conceptual design process.
High-fidelity on the other hand looks much more like what the real product would be. It often uses materials that we would expect to be in the final outcome. It is more accurate than low-fidelity prototyping. However, it takes a long time to build and the developers are reluctant to change something they have crafted for hours.
