TL;DR: In this paper, the authors proposed a new lean Six Sigma (LSS) approach and provided a detailed description of its phases, and also presented the views on the integration benefits as well as on how Six Sigma compares to lean.
Abstract: Purpose – Lean and Six Sigma are the two most important continuous improvement (CI) methodologies for achieving operational and service excellence in any organization. The purpose of this paper is to explain how lean compares to the Six Sigma and outline the benefits for integrating them. Also, this paper discusses the existing models that describe how Six Sigma and lean fit together. A new detailed description for integrating Six Sigma and lean is developed to provide an improved approach for CI.Design/methodology/approach – The following research included proposals and discussion, which were mainly based on the authors' own findings and experience, in addition to a literature‐based review of some of the most common and traditional lean and Six Sigma models.Findings – The paper proposes a new lean Six Sigma (LSS) approach and provides a detailed description of its phases. The paper also presents the views on the integration benefits as well as on how Six Sigma compares to lean. Six Sigma and lean are rel...

TL;DR: The literature on Six Sigma from 417 referred journal articles from 1992 to 2008 were systematically analyzed based on a scheme that consists of four distinct dimensions: publication year and journal, major themes, research type, and application sector as mentioned in this paper.
Abstract: Purpose – This paper aims to clarify emerging aspects and trends of Six Sigma literature over 17 years, from 1992 to 2008Design/methodology/approach – The literature on Six Sigma from 417 referred journal articles in business and management disciplines, information systems and computer science, engineering, healthcare, etc were systematically analyzed based on a scheme that consists of four distinct dimensions: publication year and journal, major themes, research type, and application sector (ie manufacturing vs service)Findings – A number of key findings emerged: Six Sigma research is growing rapidly, covering various disciplines and domains with a great focus on Six Sigma tools and techniques; empirical research is dominant with more emphasis on case study approach; and the growing gap between manufacturing‐ and service‐focused articles implies the return of Six Sigma to manufacturing as its initial base Although a large volume of literature is available on Six Sigma, the topic is still under deve

TL;DR: In this paper, an integrated lean six sigma (LSS) model for manufacturing industry has been proposed to provide a single and highly effective strategy for change in companies, which has been successfully implemented in a number of SMEs and evaluated for its effectiveness in the subject company.
Abstract: Purpose – Both lean and six sigma are key business process strategies which are employed by companies to enhance their manufacturing performance. However, whilst there is significant research information available on implementing these systems in a sequential manner, there is little information available relating to the integration of these approaches to provide a single and highly effective strategy for change in companies. The purpose of this paper is to develop and implement an integrated lean six sigma (LSS) model for manufacturing industry.Design/methodology/approach – Through the development of a case study approach, the paper chronicles the design, development and implementation of an integrated LSS model. The work in this paper builds upon the SME six sigma model that has been successfully implemented in a number of SMEs. The model is subsequently evaluated for its effectiveness in the subject company.Findings – This paper proposes an integrated approach to lean and six sigma model. Its developmen...

TL;DR: In this paper, a review of six sigma application in services along five main themes is presented, including the necessary factors for success, key performance indicators, critical to quality characteristics, and the benefits and limitations of applying 6 sigma in services.
Abstract: Purpose – Since its introduction by Motorola in the 1980s, six sigma and its philosophy have found widespread application in many manufacturing industries. It has also inspired applications in service industries. It is felt that there is a need to take stock of the knowledge accumulated in what is now an emerging field of study and look for directions to take the application of six sigma further in services. This article aims to review six sigma application in services along five main themes. The article seeks to draw on these themes to reflect on the wider applicability of six sigma in services.Design/methodology/approach – An analysis of relevant publications, citations and references was carried out using multiple databases. The impact of various key researches in this area is also discussed. The analysis then moves to discussing the necessary factors for success, key performance indicators, critical to quality characteristics, and the benefits and limitations of applying six sigma in services.Findings...

TL;DR: In this paper, the authors define six sigma in an engineering design context and present an implementation of a robust optimization formulation that incorporates approaches from structural reliability and robust design with the concepts and philosophy of 6 sigma.
Abstract: The current push in industry is focused on ensuring not only that a product performs as desired but also that the product consistently performs as desired. To ensure consistency in product performance, "quality" is measured, improved, and controlled. Most quality initiatives have originated and been implemented in the product manufacturing stages. More recently, however, it has been observed that much of a product's performance and quality is determined by early design decisions, by the design choices made early in the product design cycle. Consequently, quality pushes have made their way into the design cycle, and "design for quality" is the primary objective. How is this objective measured and met?
The most recent quality philosophy, also originating in a manufacturing setting, is six sigma. The concepts of six sigma quality can be defined in an engineering design context through relation to the concepts of design reliability and robustness --- probabilistic design approaches. Within this context, design quality is measured with respect to probability of constraint satisfaction and sensitivity of performance objectives, both of which can be related to a design "sigma level". In this paper, we define six sigma in an engineering design context and present an implementation of design for six sigma --- a robust optimization formulation that incorporates approaches from structural reliability and robust design with the concepts and philosophy of six sigma. This formulation is demonstrated using a complex automotive application: vehicle side impact crash simulation. Results presented illustrate the tradeoff between performance and quality when optimizing for six sigma reliability and robustness.
