Investigations indicate that different types of work environment problems in computer supported work are constantly increasing. Most efforts to improve the work environment are focused on physical or psychosocial aspects, since these are easier to measure and provide efficient solutions to. Mental workload and cognitive problems are of a more complex nature, and are therefore more seldom studied and solved. Solutions to work environment problems are usually applied to already constructed work situations through health programs, education, reorganizations, etc. The problems are seldom prevented by methods applied early in the systems development process, i.e. before the artifacts have been designed and implemented. This, and the following papers of the session, will focus on the need to integrate different interdisciplinary methods in the analysis, design and evaluation of computerized work situations, aimed at preventing work environment problems.
