An Elemental Resource for the Human-Task Interface

Abstract

The elemental resource model (ERM) attempts to provide a quantitative and straightforward framework for characterizing the human system, tasks, and their interface. It evolved in large part from the general systems performance theory (GSPT), which was developed first and independently. Resource constructs are used exclusively for modeling the abstract idea of system performance and for subsequent measurement of performance resource capacities. Resource economic principles provide a cause-and-effect description of the human-task interface. While argued to have immediate utility, it also provides the motivation to consider coordinated, collaborative, long-term developments that could facilitate effective decision making and technology utilization in rehabilitation.
