Abstract: The application of lean thinking has made a significant impact both in academic and industrial circles over the last decade. Fostered by a rapid spread into many other industry sectors beyond the automotive industry, there has been a significant development and “localisation” of the lean concept. Despite successful “lean” applications in a range of settings however, the lean approach has been criticised on many accounts, such as the lack of human integration or its limited applicability outside high‐volume repetitive manufacturing environments. The resulting lack of definition has led to confusion and fuzzy boundaries with other management concepts. Summarising the lean evolution, this paper comments on approaches that have sought to address some of the earlier gaps in lean thinking. Linking the evolution of lean thinking to the contingency and learning organisation schools of thought, the objective of this paper is to provide a framework for understanding the evolution of lean not only as a concept, but also its implementation within an organisation, and point out areas for future research.

Abstract: Six Sigma is a business strategy and a systematic methodology, use of which leads to breakthrough in profitability through quantum gains in product/service quality, customer satisfaction and productivity. The concept of implementing Six Sigma processes was pioneered at Motorola in the 1980s and the objective was to reduce the number of defects to as low as 3.4 parts per million opportunities. For the effective implementation of Six Sigma projects in organisations, one must understand the critical success factors that will make the application successful. This paper presents the key ingredients, which are essential for Six Sigma implementation. These ingredients are generated from a pilot survey conducted in the UK manufacturing and service organisations.

Abstract: Purpose - The authors analyze the principles and results of lean production and compare the lean production philosophy with the six sigma quality process and the principles of total quality management (TQM). At the end of the paper, it is discussed how to build the necessary company culture for having success with these principles/management philosophies. Design/methodology/approach - Literature search and comparative analysis complemented with a Danish case on wastage in a core process. Findings - It is shown that the lean production philosophy and the six sigma steps are essentially the same and both have developed from the same root - the Japanese TQM practices. The improvement process from six sigma, the DMAIC process, can be regarded as a short version of the Quality Story, which was developed in Japan in the 1960s as a standard for QC-circle presentations. We conclude that the roadmaps of lean production and six sigma quality are examples of new alternative TQM roadmaps. We also conclude that especially with lean production and six sigma quality there seems to be too much focus on training people intools and techniques and at the same time too little focus on understanding the human factor, i.e. how to build the right company culture. Originality/value - The detailed and historical analysis of six sigma quality, lean production and TQM combined with a focus on the human factor and the needed corporate culture. © Emerald Group Publishing Limited.
