Learning on lean: a review of thinking and research

Purpose – The purpose of this paper is to present an analysis of research on lean production (LP) since the concept was developed at the end of the 1980s with the aim of developing a model that permits an extended and comprehensive understanding of LP. Design/methodology/approach – A literature survey of peer reviewed journal articles and paradigmatic books with managerial impact is employed as the research methodology. Findings – The findings derived from the evaluation of the publications analysed have led to the creation of an extended model of LP. Specifically, two new groups of factors to be taken into account in order to achieve a comprehensive understanding of LP are presented. Apart from internal aspects at the shop floor level and value chain elements, the model provided includes work organisation and the impact that the geographical context has on LP. In addition, the critical assessment of publications has allowed a number of specific aspects to be identified for which there is no empirical evidence. Originality/value – This paper puts forward a new classification of literature identifying key aspects that should be included for LP development and management. It might represent new opportunities for rigorous and relevant research that would contribute to more transparent knowledge of LP being gained.
