it's not frankensteining: why you should be building twin prototypes
DESCRIPTION
Slides from a presentation by Will Myddelton at UX Lisbon 2014. Watch the actual presentation here: http://vimeo.com/myddelton/not-frankensteining When developing new product ideas a single prototype is simply not enough. Building and testing twin prototypes allows you to assess competing hypotheses (great for settling arguments), lets your clients to contribute design ideas (amazing for buy-in) and keeps radical ideas in the design process for longer (essential for developing fragile concepts into stronger ones).TRANSCRIPT

Not Frankensteining • Focus relentlessly on named hypotheses
• Gather input from users doing tasks (not clients)
• Use what you learn in the next round of design

Testing prototypes
• Sell the idea on the time and money it will save.
• Commit yourself to twin prototypes in advance.

Testing prototypes
• Be big and bold and explicit with hypotheses.
• Test things you think you know the answer to.

• Don’t give yourself too much time to prototype.
• Ensure each prototype is internally consistent.
