Prototype

A prototype is an early sample, model, or release of a product built to test ideas, demonstrate a concept, or validate design choices. The term comes from Greek protos, meaning first, and typos, meaning impression or form. Prototypes are used across industries to explore feasibility and communicate a vision before committing to full production.

In product development, prototypes help teams assess form, function, and manufacturability, and to identify technical or logistical risks. They can be throwaway, intended to be discarded after learning, or evolutionary, refined into the final product through successive iterations. Prototyping supports decision making about materials, performance targets,成本, and scheduling.

In software and digital design, prototypes range from low-fidelity sketches or wireframes to high-fidelity interactive simulations. They enable user testing, requirements clarification, and interface exploration. Prototypes may be non-functional or partially functional, depending on the goals of the study. A minimum viable product is related but distinct, often representing a functional release used to gather real-world feedback.

Common prototyping methods include physical models created with 3D printing, CNC machining, or hand-built mockups, as well as digital simulations and virtual prototypes. Rapid prototyping emphasizes speed and iterative learning, shortening development cycles and reducing risk by validating concepts early.

Prototyping is a development tool rather than an end product. It helps align stakeholders, evaluate design choices, and inform decisions about materials, cost, and manufacturing pathways. Clear objectives and documentation enhance the value of a prototyping effort.
