Abstract

The paper proposes CQFAU, a new questionnaire for usability assessment, designed for simplicity yet capable of obtaining information on improvement directions suggested by respondents. It differs from the available questionnaires having similar purpose in its scope (focusing at specific function of the software rather than its general impression), question form (using a set of binary questions followed by a single open one), and the cascading structure (presenting further questions only to respondents who are considered knowledgeable to answer them). The paper describes the instrument, explains how it can be used to identify flaws in software usability and for benchmarking usability, and reports the results of its preliminary evaluation.
