Abstract: BACKGROUND:Design in use and inventiveness are key concepts in ergonomics. It is well-known that users design but is not explored in the literature how they manage to do that. OBJECTIVE:This paper aims to contribute to the discussion of how users actually design, by showing a research conducted in sugar cane harvesting in Brazil and in Australia. METHODS:Through the methodology of the Ergonomic Work Analysis (EWA), the design modifications made by the harvesting teams were identified as well as their elaboration process. RESULTS:Three categories of modifications in machines’ design were identified: structural, functional and operational and they were more numerous in Brazilian situations. It is proposed that two theories underlying the theme are intertwined: the instrument-mediated activity approach and the design as bricolage. CONCLUSIONS:It is argued that users design through the articulation of: a) the operators’ activity, b) the mechanical technicians’ inventory to practice bricolage as a way of designing and c) the work organisation and the existence of social spaces of interaction between these two subjects.
