The ADA project

Computer technology is today rapidly transforming working life. It has a great impact on working conditions, as well as on health and well-being of individuals. An increasing number of people are frequently using computers as integrated tools in their daily work environment.

There is a long tradition of using different methods for tests and evaluations of information systems and user interfaces. This paper introduces a method, the ADA-method, for usability evaluation of established information systems, used by skilled professionals. It is intended to be used by occupational health care organisations, as a complement to their more traditional methods for investigation of the physical and psycho-social work environment.

The objectives of the developed ADA-method are

  • to identify usability and cognitive work environment problems in computerized work situations, and
  • to be a basis for further analysis and discussions concerning improvements of the system. The intention is not to cover all possible usability aspects, but to identify major usability problems related to efficiency of the system and to user’s cognitive work environment.

An evaluation with the ADA-method is performed as an observation interview, during which the observer documents findings for further analysis.

The project was completed 1996.
