Prototyping and Fidelity

Prototyping is how a designer turns an idea into something they can test.
It is a core step in the iterative design process: build a version, get feedback, improve it, and repeat.

Definition

Prototyping

Prototyping is the process of creating a model or early version of a product to explore ideas, test concepts, and gather feedback before final production.

Prototypes differ in fidelity, the level of detail, sophistication, and realism a model has.
The two techniques are low-fidelity and high-fidelity, and which you use depends on the stage of development.

Aspect	Low-fidelity	High-fidelity
Detail level	Basic, conceptual	Detailed, realistic
Cost and time	Low	High
User feedback	Focuses on core concepts	Provides accurate insights
Flexibility	Easy to modify	Harder to change
Use case	Early-stage exploration	Final-stage testing and presentation

Low-Fidelity Prototyping

Definition

Low-Fidelity Prototypes

Simple, quick, and inexpensive representations of a product. Often made using paper, cardboard, or rough digital sketches.

Low-fidelity prototypes are quick, cheap, and rough, made from paper, cardboard, or simple sketches, and they belong in the earliest stages where you need fast answers across many possible solutions.
Their weakness is realism: they cannot support real user interaction, so they are not enough for detailed usability testing.
