It is very important to assess the usability of an IT tool as well as its efficiency and its effect on work environment. We know from previous research that user participation, system function, user competence and adaptation to organizational structures are significant factors that affect decisively the usability of IT tools. In the present work these factors have been correlated to work environment, user health and efficiency of IT tools. The main goal was to investigate if it is possible to construct a questionnaire by which the relationship between usability, work environment and efficiency can be assessed. The questionnaire was focused mainly on whether and how personal skills and organizational processes contributed to successful user participation and through that to usable IT tools, to better work environment, and to higher efficiency. Participants were employees in two big Swedish government organizations. They were users of two different IT tools. The results showed that the structure and the content of the questionnaire make it possible to build an index for the assessment of IT tools’ usability correlated to work environment and organizational efficiency. High levels of reliability and satisfactory psychometrical features were obtained. The analysis showed that the factors identified were in accordance to the original hypothesis. Organizations that purchase, develop, install and use IT support tools are very much interested in assessing the usability of these tools. However, the proposed index provides only an indicative value. Further differentiated assessments and additional investigations are necessary to get a deeper, more detailed and more accurate picture. The proposed usability index functions well as a quick and easy indicator of current conditions but also as an evaluation method of certain measures taken, and as a method to follow continuously the usability value of an IT tool over a longer period of time.
