Integrating work environment considerations into usability evaluation methods - the ADA approach

The ADA method is an attempt to integrate work environment issues into a usability evaluation method. The intention is to provide a method that can be used for the analysis of computer systems that are used by skilled professionals as a major part of their work. An ADA-analysis is performed as a semi-structured observation interview. The objectives of the ADA-method are (1) to identify usability and cognitive work environment problems in a computer supported work situation, and (2) to be a basis for further analysis and discussions concerning improvements of the system.
