Resources: Usability in the Real World
Overview
Usability is not just about research and labs. It has a real impact on real projects in the real world.
UPA collects case studies, news stories, facts and examples to help make the case that usability is a critical part of any product development effort.
The UPA project on Usability
in the Enterprise
studies how usability is used and measured in industry.
In a 1990 paper, Claire Karat did a cost-benefit analysis that suggested that an investment in usability engineering can product a return on investment in the range of 3:1 to 100:1.

The payoffs included:
- Fewer last-minute design changes
- Usable, appealing, and effective designs
- Simple, less costly documentation
- Credible marketing claims
- Compelling product demonstrations
- Increased sales
- Reduced need for customer support
- Longer market life
