Comparative usability measurement: the role of the usability lab in PC Magazine UK and PC/ Computing

Abstract

PC Magazine UK and PC/Computing have pioneered the development of formal comparative usability testing, in response to the changing objectives and requirements of their readership. The comparative methodology is labs-based and follows a strict series of procedures during the design, implementation and analysis of tests. Carefully selected testers work with the products under review and subjective and objective measures are recorded, from which a comparison of all products can be derived. The end result of the comparative methodology is the ranking, or sorting, of products within the same category, in order of their usability. This information is presented to readers as a basis for product choice; and to vendors as a guide to the strengths and weaknesses of their product in relation to its competitors.
