Motivation -- Development of complex system interfaces can benefit, in addition to the traditional safety focused evaluation, also from a usability approach to evaluation of system performance. But as the users, the information system, and the controlled process constitute a complex system, the usability evaluation method needs to be extended to cover the systemic aspects of the activity under evaluation. Research approach -- The research approach is constructive. By following a control room modernisation case and by conducting evaluations, a method to be used in the evaluation is constructed. Findings -- A new construct: Systems Usability is introduced. Systems usability raises usability evaluation from analysing user tasks to the level of analysing user activity. A method to assess systems usability is outlined. Although the construct has been created in nuclear industry, it has relevance also with regard to other complex systems. Take away message -- In evaluating complex system user interfaces, such as e.g. in nuclear power plant main control rooms, the whole activity in which the new user interface is adopted needs to be considered.
