Product prototyping

Building a product from a user-endorsed prototype reduces the cost and engineering effort required. It also increases the likelihood of long-term user adoption.

What about testing?
Prototyping is iterative — we build on and evolve what worked and learn from what doesn’t. A successful prototype invites improvement. Early prototypes could be rudimentary sketches. Later prototypes often mirror the final solution. With each iteration, the ‘fidelity’ of a prototype gradually improves. Wireframe quality becomes a design that looks and feels like the product.
