The purpose of this paper is to evaluate how temporary labor moderates the relation between two well-known lean initiatives (process flow and process quality) and line productivity. This paper focuses on high-volume, low-variety (HVLV) shop floors, where work experience may not be as relevant as expected and extrinsic motivation of the temporary workforce could become a key driver of individual performance.

The authors follow an insider econometrics approach based on panel microdata (1,793 observations) from nine lines over two years in a Spanish manufacturing plant. The authors selected this setting for two reasons: Spain has traditionally had one of the highest levels of temporary employment in the world, so it perfectly represents labor market trends in OECD countries. Simultaneously, the authors also searched for a type of shop floor that could be representative of one of the most common manufacturing environments: a shop floor with highly repetitive and low-complexity work tasks.

The results of this paper suggest that in HVLV environments, temporary labor could contribute up to a 1.4% improvement in line productivity, provided there is a strong lean implementation. Otherwise, the use of temporary labor could undermine the positive effects of both process flow and process quality on plant productivity.

External incentives derived from high levels of unemployment, coupled with manufacturing’s increasing automation and specialization, may be minimizing the weaknesses traditionally associated with temporary workers in lean environments. By contrast, those shop floors lacking lean standards face serious productivity consequences from adjusting to global trends by using temporary work.

Whilst capabilities in exploiting existing assets and simultaneously exploring new opportunities have proven essential in today's organisations, an understanding of how these so-called ambidextrous capabilities are deployed remains elusive. Thus, the authors aim to investigate the role of better management practices (BMP), as organisational routines, in deploying ambidextrous capabilities in practice.

High-variety, low-volume (HVLV) manufacturers are adopted as exemplar ambidextrous organisations. A conceptual model was developed where BMP, including human resource management (HRM) and production planning and control (PPC), are considered as mediators in the relationship between ambidextrous capabilities and organisational performance outcomes. Partial least squares structural equation modelling was adopted to analyse the results of a survey undertaken by Australian HVLV manufacturers.

The results suggest that merely holding ambidextrous capabilities is not enough – demonstrating a fully mediating role of BMP between ambidextrous capabilities and HVLV manufacturer performance outcomes. However, the individual effects of PPC and HRM prove varied in their unique impact on HVLV manufacturer performance.

This study also provides a rare account of how HVLV manufacturers can leverage their inherently ambidextrous design towards greater organisational performance and highlights critical considerations in the selection of organisational capabilities.

By exemplifying the explanatory power of BMP in ambidextrous capability deployment, this study moves beyond the more prevalent stance on the links between BMP and ambidextrous capabilities as that of capability building through management practices, to one concerning the deployment of the capability itself.

Much has been written and talked about on the subject of lean manufacturing (LM) since the idea was first defined by Womack, Jones and Roos. This has stimulated academics and practitioners within various sectors of manufacturing industry to assess the viability of applying lean manufacturing principles to their circumstances. Addresses the vexing question asked specifically by many manufacturers in high variety, low volume (HVLV) segments: “Can we either directly or in adapted form apply LM principles and, if so, how do we go about it in our circumstances?” First describes the main characteristics of HVLV situations and then, drawing from experience of such organizations, contrasts these characteristics with those of the typical large lean manufacturing company. Uses this discussion as the framework to debate some of the major organizational and technological barriers which need to be overcome in applying lean principles in HVLVs. Then proposes approaches which feasibly can be considered when implementing lean manufacturing principles within a typical HVLV situation. Concludes with examples of the application of these principles to real situations in two case companies. The cases present instances of how organizations adapt lean principles to design and implement logistics and manufacturing operations for leanness, in creating and leveraging integrative supplier relationships and in evolving towards a process orientation which permits the institution of consistent measures to gauge strategic performance.

Although leanness is certainly not a new concept it is doubtless still relevant. Interestingly, newly developed manufacturing paradigms and systems are always examined in relation to leanness. In other words, leanness serves in most cases as the landmark paradigm with which comparisons are being drawn between the latter and recently pioneered approaches. The purpose of this paper is to highlight the evolutional orbit that leanness has followed over the years and serve as a herald of the current state of this evolution, which will be discussed further, in a separate paper.

A great part of this paper is devoted to highlighting the misconceptions surrounding issues such as what leanness really constitutes and what are the key concepts and practices that leanness encompasses. Two successful lean transition stories are presented showing how these lean tools and techniques were implemented in the cases of two UK‐based manufacturing companies.

Because of its inherently dynamic nature, leanness has undergone and still is undergoing a process of continuous and never‐ending evolution, the current state of which is expressed in the form of the lean enterprise model. Nevertheless, despite the undiminished attention and interest for leanness, the literature has failed to keep track of this evolution. For this reason a significant proportion of the literature relies on a rather antiquated vision of leanness.

The paper reviews two major waves of literature criticising leanness with the first focusing on its social aspects and the second questioning its universality mainly with respect to its limited applicability in high variety‐low volume production systems.
