Usability Evaluation Methods

Usability evaluation is a set of methods used in the area of human-computer interaction to increase the efficiency, effectiveness and user satisfaction when interacting with any form of computer or more general any form of information and communication technologies. The document ISO 9241-11 18 Guidance on Usability (ISO, 2008) specifies usability as: “The extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use.” A major issue for products and services being mass customized is the overall utility of such systems or products. The area of usability evaluation today can be summarized as all forms of methods that can help to understand how to improve the usability of a system, to investigate usability problems in all kinds of usage contexts, or even to understand the long-term usage of a product in the field to inform new generations of the product.
