Prototype development

Satisfying the Brief: Prototypes test whether a product meets the goals and constraints of the design brief.
Responding to Clients: Prototypes allow clients to give feedback and influence the design direction.
Innovation: They support creative risk-taking and experimentation before final commitment.
Functionality: Allows designers to test how something works in real-world use or conditions.
Aesthetics: Helps refine colour, shape, finish, and overall appearance to suit the user or market.
Marketability: A strong prototype can help sell the idea to stakeholders or manufacturers.

Reflect Critically: Consider what works, what doesn’t, and why — based on both personal judgement and user feedback.
Respond to Feedback: Adjust designs based on input from clients, users, and peers.
Suggest Modifications: Improvements can be suggested to materials, ergonomics, shape, or layout.
Improve Function and Performance: Development should solve identified issues or weaknesses.
Assess Fitness for Purpose: Evaluate whether the prototype works effectively, is safe, and is ready for market.

Advantages of Prototyping	Disadvantages of Prototyping
Helps identify issues early Supports communication with users/clients Can save money before mass production Improves quality and usability of final product	Time-consuming to build and test May require expensive materials or tools Some features may be hard to prototype accurately
