Quality of Web Usability Evaluation Methods: An Empirical Study on MiLE+

What are the quality factors that define a “good” usability evaluation method and contribute to its acceptability and adoption in a real business context? How can we measure such factors? This paper investigates these issues and proposes to decompose the broad, general concept of “methodological quality” into more measurable, lower level attributes such as performance, efficiency, cost effectiveness, andlearnability. We exemplify how to measure such attributes, reporting an empirical evaluation study of a usability inspection method for web applications called MiLE+.
