Personal skills and group processes are necessary in the production of knowledge to design and manage usable systems. AvI is a questionnaire that correlates these parameters of usability to utility and work environment. The main goal of AvI is to create a description of the processes that are necessary to achieve good usability: user participation, knowledge support, networking for coordination and cooperation etc, defined as philosophizing processes at personal and group levels. AvI’s ambition is to indicate whether the preconditions for these processes are present in an organization, to allow these to arise and to function in a satisfying and fruitful way. The evaluation of AvI showed that reliability coefficients and correlations to independent criteria were high, supporting the original hypothesis: AvI can be used to acquire information about the above parameters of an IT system’s usability in an easy and quick way. Although AvI only provides an indicative value, such a diagnosis of the usability of an organization’s IT infrastructure is valuable as an alert and to determine the extent of further initiatives.
