Usability of IT-Systems is More than Interaction Quality : The Need for Communication and Business Process Criteria

• The design and evaluation of IT-systems are usually supported by different usability criteria. Our hypothesis is that criteria are predominantly formulated as supporting interaction between a user and an IT-system. We are claiming that there is a need for criteria formulated at higher levels such as communication and business processes. One example of a criterion formulated at the interaction level is "Visibility of system status" and one example of a criterion formulated at the business process level is "Quality of work". If criteria is formulated and used on the interaction level only, the impact on design and evaluation can only take place at this level. This choice will also mean that you are only able to speculate whether the IT-system is supporting higher levels. We are not saying that criteria belonging to the interaction level are unimportant; rather we are saying that there is a need for formulating complementing criteria that resides on the communication and business process level.
