Ergonomics research focuses on two areas: the different activities performed by workers within their work environment and professional ergonomics practice engaged in bringing about activity change. The modelling of such practice plays a major role in fostering the education of new professionals, as well as in debates that may result in an improvement in ergonomic practice itself.
This paper focuses on the data which is generated by the interventions of ergonomics practitioners aimed at changing workplace design. Five categories of data are identified. The first category relates to the data derived from the initial assumptions of ergonomics practitioners. The second category corresponds to the components of intervention methodology and the strategy used for their formation. The third category of data relates to the internal dynamics of the components which make up intervention. The fourth class of data relates to the way that practitioners deal with situation reversals. The fifth category comprises data which enable researchers to clarify the results and consequences of intervention. Finally, this paper discusses the use of all data classes to produce a narrative account of the intervention report.
