Abstract

This article presents a participatory intervention in a furniture manufacturing company in Southern Brazil aiming to improve both ergonomic and production outcomes. The existing Tayloristic model was replaced by a cellular teamwork model. Work enlargement and enrichment, and the improvements in workstation design and process flow increased worker satisfaction and reduced postural risk, fatigue, body pain and production waste. Workload was reduced by 42% and productivity increased by 46% (25% being attributable to unnecessary load handling, waiting and transportation, and 21% attributable directly to manufacturing times). Workers' participation in the stages of problems identification, design and evaluation of solutions played a major role in these outcomes.

Relevance to industry

This study indicates that it is possible to balance ergonomics and production demands, and that it is necessary to make it clear to management. The integration of macroergonomics and production management principles increases both worker well-being and productivity levels, thus leading to a more sustainable system.
