1. IDEO and the Palm V Mock-up in the Product Development Process

2. Prototype for different purposes

3. Fail often to succeed sooner Generate a fountain of idea Absurd-appearing but innovative Make models to test the ideas Select the best idea and iterate You learn just as much from a model that’s wrong as you do from one that’s right - Steve Vassallo, IDEO

4. Pit-falls Unable to precisely predict  Outcome  Time  Cost Unable to make keep client involved Creeping elegance – perfection that leads to cost and time overrun

5. Never go to a client meeting without a prototype - Dennis Boyle, IDEO

6. Rapid, Rough, Right Rapid: Take the fastest route, not necessary the most high-tech one Rough: Don’t spent time and effort on unnecessary details Right: Actually help you to make correct decision

7. Rapid Despite the popularity of Palm III, little user preferences exists Create observational database by giving out palm pilots to colleagues and friends Feedback emails point out:  Breaking after being dropped  Case rigidity  Battery door placement  Location of stylus holder

8. Rough Quick and dirty prototyping allowed for a greater number of iterations Create early prototype from readily available materials  Wood  Cardboard  Foam  Lego  Erector sets

35. Mock-ups Mock-ups are used by designers mainly to acquire feedback from users about designs and design ideas early in the design process. Mock- ups are 'very early prototypes' made of cardboard or otherwise low-fidelity materials. The user, aided by the designer, may test the mock-up (imagining that it works) and thus provide valuable feedback about functionality/usability/understanding of the basic design idea/etc. By Mads Soegaard for Wikipedia

36. The Advantages of Mock-ups Mock-ups incite criticism from users because they are low-cost (can be made of cardboard) and low-fidelity. If a user is presented with an early version of a system that has required substantial work, he/she is likely to be more reluctant (as well as able) to critise it. When using mock-ups of cardboard or similar materials, the user and designer can collectively change the design using familiar tools such as pens, scissors etc. As such, mock-ups are a discussion medium and a discussion facilitator between designer and user. Not only can the mock-up function as a discussion medium between designer and user but also between the members of the design team. Thus, mock-ups may help facilitate work across disciplinary borders, bringing together a disparate team. Mock-ups make it possible to do usability testing early in the development process. Mock-ups incite and legalise experimentation as they are inexpensive to alter. Mockups focus on content and functionality and turn attention away from details of graphic design.
