Usability and the Digital Library
As a librarian, what set of assumptions do you make about your users when you create digital library resources?
Usability DefinedUsability studies how users engage a given product. It draws from the principles of user-centered design, which places successful user interaction with a product as key to redesign.
Usability is not a focus group—we are not testing whether users like the product (solely); rather we are testing their ease-of-use or navigational success of a product.

Iterative Design
Iterative design is a process whereby the usability test results of a product lead to multiple stages of redesign. This means users give feedback on the product at all points in the product’s design: from planning, to building, to finishing the product. Iterative design centers the user in building products and systems.
