Abstract

The usability of a product or service can mean the difference between product success or failure in both the field and the marketplace. Successful products are easy to use and intuitive for the user. There are a set of well-defined methods used to determine if a product, service or system is usable and meets the needs of the end user. This paper describes the four major methods of usability assessment: 1) Inquiry Methods, 2) Inspection Methods, 3) Observation Methods and 4) Automated Methods. Each method and its attendant sub-methods are described, as is a discussion of the methods’ strengths and weaknesses.
