This paper presents an example of how different field research techniques were combined to understand the demands placed on the human operator in the complex dynamic environment of an emergency ambulance control centre. Careful selection of techniques can ensure that particular kinds of information are gathered; the order in which techniques are applied can also improve both the quality of data gathered and the efficiency of data collection. This is particularly important when studying complex information systems where the risk of being overwhelmed by data is high. Qualitative and quantitative techniques can profitably be applied together and triangulated to give added confidence to findings.
