The topic of the present contribution is the design of information systems to support work in a period of a very fast pace of change of technology, of market conditions, and company policies. Under such conditions, effective systems can no longer evolve by incremental empirical adjustment and design must be based on a predictive conceptual framework.For many modern work systems, stable work procedures are not the norm.Most of the time, tasks are discretionary, explicit consideration of goals and constraints and an exploration of the boundaries of acceptable performance is required. In this case, the object of modeling no longer is the "task" but includes all the features of the work environment and the interpretation of these features by the actors, all of which in interaction create the task ad hoc. The objects of modeling, therefore, are 1) the features of the different work domains and 2) the resource and preference profiles of the individual actors who are placed in the work domains.
