GUERRILLA TESTING
HOW WE DID IT
1. Identified web design parameters to meet Ronda needs
2. Create a PC and a mobile prototype
3. Conduct guerrilla testing on the prototypes
o Test the users in their natural environments

GUERRILLA TESTING
HOW WE DID IT: DESIGN PARAMETERS
Identified web design parameters based on
“Don’t Make Me Think! A Common Sense Approach
to Web Usability”
by Steve Krug

GUERRILLA TESTING
HOW WE DID IT: DESIGN PARAMETERS
1. Name of things must be intuitive
2. Links and buttons are obviously clickable
3. Clear visual hierarchy on each page
4. Minimize noise
5. Persistent navigation one each page
6. You are here – give clear visual indicators of location of the site
7. Breadcrumbs – navigation path from home page to present page
8. Make it easy to recover from errors

WHY WE DID IT
• Users have certain goals & expectations when interacting with a
product
• Understanding the user goals, behaviors, and patterns
o Help define the important attributes users possess
• Personas aim to capture those attributes
• We wanted to create a prototype that better met the user’s needs
