paper prototype tests User Interface before writing code.. paper prototyping does not explain how the interface is supposed to work, but merely simulates what the interface would do. In this manner, you can identify which parts of the interface are self-explanatory and which parts are confusing.

[edit] benefits

1. Test your design with users before you code
2. Make fast changes
3. Find out what marketing really wants
4. Eliminate technology variables from the usability testing equation

[edit] does

• test concept, UI keywords
• graphics

[edit] does not

• prove the tool can be made
• scroll

[edit] conclusion

It's normal for interfaces to undergo big changes from concept to release. No one like writing code that has to be scrapped. Paper prototyping lets you find problems early in the design process, so you can find the best solution before investing the effort to make it real.
