Usability is the ease of use and learnability of a human-made object.

The object of use can be a software application, website, book, tool, machine, process, or anything a human interacts with.

A usability study may be conducted as a primary job function by a usability analyst or as a secondary job function by designers, technical writers, marketing personnel, and others.

It is widely used in consumer electronics, communication, and knowledge transfer objects (such as a cookbook, a document or online help) and mechanical objects such as a door handle or a hammer.

Usability includes methods of measuring usability, such as needs analysis and the study of the principles behind an object's perceived efficiency or elegance.

In human-computer interaction and computer science, usability studies the elegance and clarity with which the interaction with a computer program or a web site (see web usability) is designed.

Usability differs from user satisfaction and user experience because usability also considers usefulness.
