The iterative process of creating preliminary versions of a product or system to test concepts, validate assumptions, and gather feedback before final implementation.

Prototype Development

Prototype development is a crucial phase in the product design process where initial versions of a product are created to explore, test, and refine ideas before committing to full-scale production.

Core Principles

1. Iterative Refinement

Multiple iterations of prototypes, each building on lessons from previous versions
Progressive improvement through feedback loops
Balance between rapid prototyping and detailed refinement

2. Risk Reduction

Early identification of design flaws
Validation of technical feasibility
Mitigation of project risk management factors

Types of Prototypes
