This paper discusses a number of considerations involved in the setting up of an investigation dealing with the problem of being able to draw conclusions from a variety of experimental measures in a complex task situation. Several implications are pointed out, such as the problem of dealing with contradictory outcomes, the designating of artefacts, and the problem of formulating final conclusions without the (a-priori) availability of a superior method for evaluating other methods. Finally, an experimental program is outlined which is based on (normal) approach conditions for civil fixed wing aircraft. The task conditions in this experiment have been selected to serve as an operationally based framework for comparing different workload evaluation methods, for evaluating the effects of specific tasks conditions and for investigation the strategies needed for drawing final conclusions from a variety of outcomes. A discussion is given of some experimental results involving subjective ratings, heart rate measures and tasks performance measures.
