Usability Methods Explained: Paper Prototyping Part – 1
This blog post is the second in a series of two about paper prototyping as a usability method.
How do you undergo usability testing with paper prototypes?
Paper prototyping as a usability test works best in the format of a workshop that is attended by both users and developers. You should select users that represent the demographic targeted by your interface design. Tasks, or use cases, have to be designed for users to go through before you can create the paper prototypes. Make sure to review your paper prototypes before you use them in a usability test. During the usability test it is important to have a good facilitator, someone who is able to take note of issues raised and encourage users to be open and communicative with their feedback. At the end of the usability test, make sure that the facilitator communicates the feedback/results to the rest of the team.
The four stages of prototyping
Paper prototyping is usually performed in four stages:
1. Concept design state. During this stage you brainstorm different approaches and strategies with a view of learning which thereof fulfills the targeted usability requirements.
2. The interaction design stage. This is when you organize the structure of your different interface designs.
3. The screen design stage. This is when you create the initial graphical user interface designs by drawing them on paper.
4. The screen testing stage. This is when you test and refine your interface design.
