Forty years of IEA: some reflections on the evolution of ergonomics

Abstract

This paper is the IEA Presidential Address to the 1997 IEA Triennial Congress in Tampere, Finland. The evolution of ergonomics prior to and after the foundation of the International Ergonomics Association in 1957 is reviewed. Ergonomics has broadened from considering work activities to include all types of human activities. The recent introduction of computers has changed many of the premises for work and leisure activities, and cognitive ergonomics is now as important as the ‘biological’ emphasis that was mentioned in the founding documents of IEA. Ergonomics is a science of design. There are three important targets for ergonomics design activity: to improve safety, productivity and operator satisfaction. A systems approach is presented to define how these parameters interact and how they can be measured.
