Cool, but not intuitively obvious...
people respond to software & hardware that is easy to use.

mental models?“Things should work the way we think they should work...
... if you break the user’s mental model - they respond negatively.”

value proposition...Every dollar invested in Usability returns $10 to $100
A proactive usability practice enables a company to:
realize better business requirements (become strategic)
establish a new value proposition (learn from the users)
reinvent your software or hardware assets
attract and retain target audiences

some conclusions...1. Watch five people user your web application.
2. Listen to how they approach specific tasks.
3. Think from the users point of view.

what’s behind the emotions...
the designers ability to persuade (PET design)
• scarcity
• reciprocity
• authority
• likability
• commitment and consistency
• social proof
![Page 44: Value and Politics of Usability](https://reader035.vdocuments.mx/reader035/viewer/2022062615/5481571fb379593f2b8b5d7d/html5/thumbnails/44.jpg)
the politics...
![Page 45: Value and Politics of Usability](https://reader035.vdocuments.mx/reader035/viewer/2022062615/5481571fb379593f2b8b5d7d/html5/thumbnails/45.jpg)
shared space...Is Usability a task for Sisyphus?
![Page 46: Value and Politics of Usability](https://reader035.vdocuments.mx/reader035/viewer/2022062615/5481571fb379593f2b8b5d7d/html5/thumbnails/46.jpg)
a typical day...“We don’t have time for usability right now.”
“We don’t need you right now... maybe later.”
“The project is almost done. Can you check it out?”
We need partnership from the business and technical stakeholder community...
![Page 47: Value and Politics of Usability](https://reader035.vdocuments.mx/reader035/viewer/2022062615/5481571fb379593f2b8b5d7d/html5/thumbnails/47.jpg)
where in the lifecycle?Test early and often... throughout the entire lifecycle...
Wireframe prototypes are the most cost effective asset to test
the more unfinished looking the better
live sites and applications can be tested
test without constraints (explore the ideal)
