STRATUS: a Questionnaire for Strategic Usability Assessment

Strategic usability is widely recognized as a challenge, as moving from scattered to strategic usability requires organizations to operate significant changes. The current solutions are hardly accessible and complicated to implement. STRATUS is a questionnaire for cost-effectively assessing strategic usability. A companion model enables to easily analyze and describe the current state of strategic usability according to five dimensions and related indicators. A pilot STRATUS survey compared the responses between novices and experts in usability. It highlighted dependencies between experience and usability awareness, as well as positive correlations between the presence of usability staff and strategical use of usability. The questionnaire needs now to be validated by means of a longitudinal study. Another promising track towards its validation consists in further investigating the causations between the dimensions of strategic usability.
