Implementing lean production systems: research areas and opportunities for future studies

The increasing use of lean production (LP) by companies from several sectors has substantially increased the amount of publications and different emphases on the subject, which amplifies the need for organisation of that knowledge. This article aims to identify the research areas on LP implementation and to propose research opportunities. The literature review was based on 102 studies published in the years between 1996 and 2012. The studies were divided into six research areas, named: (a) structure and scope of LP systems; (b) factors that influence in the LP implementation; (c) methods for implementing LP systems; (d) LP assessment methods; (e) results of implementing LP systems; and (f) adaptation of LP to particular sectors. The findings suggested that the substantial increase on the amount of publications on LP implementation has created fragmented and dissociated areas that would benefit from integration.
