User and usability testing - how it should be undertaken?

Abstract

Usability evaluation is the analysis of the design of a product or system in order to evaluate the match between users and a product or system within a particular context. Usability evaluation is a dynamic process throughout the life cycle of a product or system. Conducting evaluation both with and without end-users significantly improves the chances of success. Six usability evaluation methods and six data collection techniques are discussed, including advantages and limitations of each. Recommendations are made regarding the selection of particular evaluation methods and recording techniques to evaluate different elements of usability.
