Summary

• Cost of usability activities
• Expected improvements in measured usability

Data collected from a large number of development projects: 72 case studies for the benefits estimate and hundreds of projects for the cost estimate.

Describes the different ways one converts usage metrics into monetary gains for different types of projects (intranets, e-commerce, marketing sites, internally-developed software, software for sale, consumer electronics and other hardware products).

Richly illustrated with 131 full-color screenshots of "before" vs. "after" designs, showing what design details worked, and how much the site's desired business metrics increased as a result of these usability improvements.
