title: Some problems of field research.
abstract: For the results of ergonomic research to be of value it must be validated on the shop floor and this involves field experiments. The aim of this article is to formulate some generally applicable ideas on the problems and strategies involved in field research. The points to be made derive from experience of research in the field extending over some 20 years. It is hoped that a realistic assessment of the problems will help contribute to their solution.
