Due to shortage of time and resources in the early phases of mobile work support development processes, it is necessary to develop a ‘quick and clean’ method for user requirements modelling. The method consists of three easy steps that anyone with an interest in human factors should be able to complete: (1) The explication of a common vision, (2) observations in the field, and (3) problem oriented focus group processes. The method is designed to generate results that may serve as a foundation for more comprehensive later stage system modelling. As an illustration of the method, a case of use is presented: The development of an electronic delivery guide (EDG) for the newspaper deliverers of a major Norwegian newspaper distribution.
