Power Of Prototyping

• Prototyping is a valuable technique.
• Goal of prototyping: Feedback
• A prototype is a question rendered as an artifact.
• A prototype helps communication: helps everyone have a concrete understanding of what others are talking about.
• Prototypes are and ought to be incomplete.
• Prototyping is a strategy for efficiently dealing with things that are hard to predict.
• Focus on goals of the design, don't settle for a fixed design.

The rights of a prototype

• not required to be complete
• should be easy to change
• gets to retire

What do prototypes prototype

there are different kinds of prototypes:

• feel: what will it look like?
• implementation: what might it work like?
• role: what might the experience be like?

Goals In Prototyping

• Maximize Learning and Communication axis
• Minimize Time to create prototype axis

Prototypes can be used for large products:

• planes
• ships
• stores etc...

It's important to have different ideas about the design to be able to find the best possible design.

Costs of changes over time

The cost of changes increases exponentially overtime because:

• people get used to the current product.
• people develop things on top of your product, that can be broken.

Therefore most changes should be introduced early.
