Alarm Bells

If the system requires a full role-out to be of any use to the customers or stakeholders.

If you can think of lots of people might want to buy the finished product/system but you can’t think of who would definitely be the first customer


What are your burning questions?

Teams from Group A ask Teams from Group B about aspects of their project’s feasibility. Team B to LIST THE MAIN QUESTIONS. 5 mins

Discuss which is THE BIGGEST QUESTION MARK identified. 2 mins

Swap over.


What is a Prototype

?


A model to test an aspect of a product’s

feasibility, dealing with the burning

questions


Types of technical prototypes

– Proof-of-Principle Prototype

– Form Study Prototype

– User Experience Prototype

– Visual Prototype

– Functional Prototype

http://en.wikipedia.org/wiki/Prototype


Proof-of-Principle Prototype

A proof of concept prototype is used to test some aspect of the intended design without attempting to exactly simulate the visual appearance, choice of materials or intended manufacturing process. Such prototypes can be used to "prove" out a potential design approach such as range of motion, mechanics, sensors, architecture, etc. These types of models are often used to identify which design options will not work, or where further development and testing is necessary.

In electronics this is sometimes: “built on a breadboard”.


Dyson – 5127 prototypes

The hammer test

When James started out he tested prototypes by dropping them down a cast iron stairway at the back of his workshop. Simple but effective.

These days Dyson prototypes must endure 550 tests. Hoses are contorted and stretched. Cleaner heads are slammed into iron table legs. Performance is tested in temperatures as low as -20c in an environmental chamber. Things haven’t changed all that much though. Every 100th bin off the production line is whacked with a lump hammer just to make sure.

Form Study Prototype

This type of prototype will allow designers to explore the basic size, look and feel of a product without simulating the actual function or exact visual appearance of the product. They can help assess ergonomic factors and provide insight into visual aspects of the product's final form. Form Study Prototypes are often hand-carved or machined models from easily sculpted, inexpensive materials (e.g., urethane foam), without representing the intended colour, finish, or texture. Due to the materials used, these models are intended for internal decision making and are generally not durable enough or suitable for use by representative users or consumers.

User Experience Prototype

A User Experience Model invites active human interaction and is primarily used to support user focused research. While intentionally not addressing possible aesthetic, this type of model more accurately represents the overall size, proportions, interfaces of a concept. This type of model allows early assessment of how a potential user interacts with various elements, motions, and actions of a concept which define the initial use scenario and overall user experience. As these models are fully intended to be used and handled, more robust construction is key. Materials typically include plywood, REN shape, RP processes and CNC machined components.


User Experience


Visual Prototype

To capture the intended design aesthetic and simulate the appearance, colour and surface textures of the intended product but will not actually embody the function(s) of the final product. These models will be suitable for use in market research, executive reviews and approval, packaging mock-ups, and photo shoots for sales literature.

Functional Prototype

To the greatest extent practical will attempt to simulate the final design, aesthetics, materials and functionality of the intended design. The functional prototype may be reduced in size (scaled down) in order to reduce costs. The construction of a fully working full-scale prototype and the ultimate test of concept, is the engineers' final check for design flaws and allows last-minute improvements to be made before larger production runs are ordered.

What about Market

Prototyping?


Sun cream on demand

What are the burning question related to the

market feasibility of this product?


The burning questions about market feasibility of sun cream

1. How much variety is required in SPF ?2. What are the primary location for sales/need?3. Will customers change their mindsets/habits?4. How many (% & Vol.) people forget to bring SC?5. What are customers willing to do to receive the

product?6. What is the required dosing sizes?


Choose a couple of the questions and discuss how you could test the

feasibility using a prototype10mins
