Abstract: Purpose – Literature reviews in the field of Lean Six Sigma (LSS) are often substantially less stringently portrayed than other empirical research. The purpose of this paper is to lucubrate on clarifying emerging aspects, trends and importance of LSS through reviewing the published literature over multiple parameters for a ameliorating and trenchant view. Design/methodology/approach – In the present study, a literature review of LSS articles is carried out over the time horizon of 14 years from referred peer-reviewed journals in business and management disciplines, information systems and computer science, engineering, healthcare, etc. While carrying out the literature review, various distinct dimensions are considered, such as publication years and journals, countries, research design, research type and application sector within industries. A descriptive evaluation of the literature body is followed by gap identification and future research opportunities. Findings – LSS research is growing rapidly, covering various disciplines and domains with a great focus on LSS tools and techniques; empirical research is dominant with more emphasis on case study approach; and growing gap between manufacturing- and service-focused articles implies return of LSS to manufacturing as its initial base. Originality/value – The review analysis entirely focuses on descriptive statistics of empirical research in LSS. The sample size includes 189 shortlisted articles in 58 journals published over a time span of 14 years (2001-2014). The paper provides both academicians and practitioners a better panorama to understand the present status of LSS for pursuing rigorous LSS research through explicating chronological emergence, challenging themes, dominating research types and application areas in LSS.

TL;DR: In this paper, a new Strategic Lean Six Sigma Framework (SLSSF) is proposed that attempts to create a more balanced and integrated approach between the Lean and Six Sigma elements and one that is capable of achieving greater efficiency of production whilst also ensuring variation reduction and CTQ issues are eradicated from the production process.
Abstract: Lean Six Sigma (LSS) has established itself as one of the key business process improvement strategies available to companies today. With roots based in the single strategies of Lean and Six Sigma, LSS offers a dual strategy towards systematically reducing waste and increasing value whilst resolving Critical to Quality (CTQ) issues that affect consistency and repeatability in a product and process. However, the predominating LSS approach is to employ the DMAIC cycle as the key driver in the implementation process. The authors argue that this reduces the effectiveness of LSS since a systematic lean thinking does not take place through this approach. This paper proposes a new Strategic Lean Six Sigma Framework (SLSSF) that attempts to create a more balanced and integrated approach between the Lean and Six Sigma elements and one that is capable of achieving greater efficiency of production whilst also ensuring variation reduction and CTQ issues are eradicated from the production process. The case stud...

TL;DR: Lean Six Sigma approach in global supply chain using Industry 4.0 and IIoT creates an ideal process flow that is highly optimized as well as perfect and free from defects and wastage.
Abstract: Global Supply Chain Management is the management of supply chains located globally. Quality control methods such as Lean and Six Sigma are used for improving efficiency and quality of production and distribution carried out by global supply chains. Lean Six Sigma eliminates unnecessary processes and defects which can benefit an enterprise from reduced costs and less wastage of resources. Industry 4.0 refers to automation of industries by the exchange of data between the supply chain and logistics. Industrial internet of things (IIoT) is industrial machines connected to the enterprise cloud storage area for data storage as well as data retrieval. Industry 4.0 along with IIoT can make a big revolution in the management of global supply chain. Lean Six Sigma approach in global supply chain using Industry 4.0 and IIoT creates an ideal process flow that is highly optimized as well as perfect and free from defects and wastage. The models proposed in this paper make the supply chain fully autonomous.

TL;DR: Lean and Six Sigma QI methodologies have the potential to reduce error and costs and improve quality within radiology, however, there is a pressing need to conduct high-quality studies in order to realize the true potential of these Qi methodologies in health care and radiology.
Abstract: Purpose Preventable yet clinically significant rates of medical error remain systemic, while health care spending is at a historic high. Industry-based quality improvement (QI) methodologies show potential for utility in health care and radiology because they use an empirical approach to reduce variability and improve workflow. The aim of this review was to systematically assess the literature with regard to the use and efficacy of Lean and Six Sigma (the most popular of the industrial QI methodologies) within radiology. Methods MEDLINE, the Allied & Complementary Medicine Database, Embase Classic + Embase, Health and Psychosocial Instruments, and the Ovid HealthStar database, alongside the Cochrane Library databases, were searched on June 2015. Empirical studies in peer-reviewed journals were included if they assessed the use of Lean, Six Sigma, or Lean Six Sigma with regard to their ability to improve a variety of quality metrics in a radiology-centered clinical setting. Results Of the 278 articles returned, 23 studies were suitable for inclusion. Of these, 10 assessed Six Sigma, 7 assessed Lean, and 6 assessed Lean Six Sigma. The diverse range of measured outcomes can be organized into 7 common aims: cost savings, reducing appointment wait time, reducing in-department wait time, increasing patient volume, reducing cycle time, reducing defects, and increasing staff and patient safety and satisfaction. All of the included studies demonstrated improvements across a variety of outcomes. However, there were high rates of systematic bias and imprecision as per the Grading of Recommendations Assessment, Development and Evaluation guidelines. Conclusions Lean and Six Sigma QI methodologies have the potential to reduce error and costs and improve quality within radiology. However, there is a pressing need to conduct high-quality studies in order to realize the true potential of these QI methodologies in health care and radiology. Recommendations on how to improve the quality of the literature are proposed.

TL;DR: In this article, a case study on the logistics services of a large consumer electronics company is performed using within-case and cross-case analyses, which discusses the implementation of Lean Six Sigma (LSS) in two internal logistics processes.
Abstract: Purpose This paper aims to analyze the application of Lean Six Sigma (LSS) framework for supporting continuous improvement (CI) in logistics services. Both the lean philosophy and the Six Sigma methodology have become two of the most important initiatives for CI in organizations. The combination of both alternatives – LSS – brings significant benefits for companies applying this method, and its influence in logistics services can be relevant. Design/methodology/approach A case study on the logistics services of a large consumer electronics company is performed. In this sector, high quality in logistics services is crucial. Using within-case and cross-case analyses, the paper discusses the implementation of LSS in two internal logistics processes. Findings The paper identifies important implementation aspects when applying LSS to logistics services, such as CI structure, strategic analysis, cross-functional teams and process management. Furthermore, the paper discusses the potential in logistics services of the DMAIC (define, measure, analyze, improve and control) approach and tools such as value stream mapping, SIPOC (supplier, input, process, output, and customer) and process mapping. Practical implications The paper analyzes two logistics processes where LSS has been applied – a payment process and a request-to-ship process. The analysis of both processes offers relevant information about organizational implementation in a logistics services environment about process improvement and about the use of LSS tools. Originality/value First, this paper addresses the gap in literature about LSS and logistics’ activities. Furthermore, the case company, with more than 9,000 employees and distributing its products to more than 100 countries, constitutes a valuable source of information to obtain insights into the implications of implementing LSS in logistics services.

TL;DR: In this paper, the authors developed a model that incorporated lean six sigma (LSS) implementation, strategic control system (SCS) and organizational performance (OP) in Malaysian automotive suppliers.
Abstract: Purpose The aim of this paper is to develop a model that incorporate lean six sigma (LSS) implementation, strategic control system (SCS) and organizational performance (OP) in Malaysian automotive suppliers. Design/methodology/approach A survey through questionnaire was conducted to determine the level of LSS implementation, SCS and OP measurement. In all, 252 sets of questionnaire were successfully collected that brought to 64.3 per cent response rate. Structural equation modeling (SEM) technique was adopted to analyze the data gathered from the survey. Exploratory factor analysis, reliability analysis and confirmatory factor analysis for testing the construct validity, test for reliability and model measurement were carried out. Findings This study has provided a comprehensive measurement instrument to implement the LSS practices, SCS and OP for Malaysian automotive suppliers. As a result, seven LSS constructs, four for SCS and four measures for OP have been identified. This research model is a mediator model in which it investigates whether the presence of SCS mediates the relationship between LSS and OP. The analysis result through the SEM method showed that SCS does not affect the relationship between LSS and OP. However, SCS is improving OP when coupled with LSS. Research limitations/implications This study has only focused on the structured relationship between LSS Construct, SCS and OP measures. It is possible for other factors in the LSS practices to be studied in future experiments such as total productive maintenance, culture change, role structure and project management skills. Originality/value Future researchers could apply the LSS, SCS and OP measurement as a benchmark for use and can be replicated in other industry or country in the world with minor modifications on the critical factors necessary to suit the goals of the organization, culture and business environment. It could also be used as a business excellence and supplier selection tool for practitioners and researchers.

TL;DR: In this article, the authors present a case study where Lean Six Sigma tools and principles were implemented in a global, service-based, logistics organisation to identify areas of improvement in the quality and timeliness of selecting and implementing a new ruggedised handheld device for field workers.
Abstract: Lean Six Sigma is an approach that focuses on improving quality of finished products and continuous improvement during the creation of these products by reducing variation and eliminating non-value-add work within an organisation. Combining the principles and tools from Lean and Six Sigma into a single ideology is not a new concept as the application of this strategy has been documented throughout many industries in numerous case studies over the years. However, literature has not provided cases of Lean Six Sigma application to the selection and application of handheld technology in the services industry. This paper presents a case study where Lean Six Sigma tools were implemented in a global, service-based, logistics organisation. The application of these Lean and Six Sigma tools and principles were used to identify areas of improvement in the quality and timeliness of selecting and implementing a new ruggedised handheld device for field workers.

TL;DR: It is demonstrated that using Lean Six Sigma tools can be invaluable to clinical restructuring and redesign and results in measurable, improved outcomes in care delivery.
Abstract: Objective Increasingly, health care quality indicators are focusing on patient-centeredness as an indicator of performance. The National Quality Forum lists assessment of patient experience, often conducted using patient surveys, as a top priority. We developed a patient-reported time stamp data collection tool that was used to collect cycle times in a safety net hospital-based outpatient pediatrics clinic. Methods Data were collected using patient-reported survey to obtain cycle times in Pediatric clinic, as well as qualitative and quantitative patient satisfaction data. Several rapid-cycle improvements were performed using Lean Six Sigma methodologies to reduce cycle time by eliminating waste and revise unnecessary processes to improve operational effectiveness and patient and staff satisfaction. Results A total of 94 surveys were collected and revealed average cycle time of 113 minutes. Our measured patient satisfaction rating was 87%. Discharge and check-in processes were identified as the least efficient and were targeted for intervention. Following implementation, the overall cycle time was decreased from 113 to 90 minutes. Patient satisfaction ratings increased from 87% to 95%.

TL;DR: In this paper, the authors present two additional representations of the classical TPS temple model stressing the intrinsic systemic effects as well as the underlying theory concepts of the TPS to allow a flawless Just-in-Time (JIT) production.
Abstract: Personal consulting experience has been showing that even many proven managers responsible for Lean Six Sigma Operational Excellence (OPEX) techniques have not fully understood the profound and comprehensive significance of Lean. Apart from the idealized interpretation of Lean boiled down to the limited concepts of Muda and Kaizen, the classical “temple” representation of the Toyota Production System (TPS) often leads to the interpretation that Lean is a toolbox from which one can select supposedly independent tools. By picking just some tools, however, the full potential of the TPS certainly cannot be exploited and—in the worst case—it may even cause production disruption. This essay criticizes the wide-spread ultra-simplification of concepts and, as a consequence, the distorted interpretation leads to an inappropriate use of the Lean tools. It presents two additional representations of the classical TPS temple model stressing the intrinsic systemic effects as well as the underlying theory concepts of the TPS to allow a flawless Just-in-Time (JIT) production. In fact, the original TPS is not a toolbox, but a comprehensive synergic tool system.

TL;DR: Results show that the Lean six Sigma group outperforms the Moderate Six Sigma group across many performance dimensions: responsiveness capability, patient safety, and possibly cost saving.
Abstract: Background Despite the increasing interest for Lean and Six Sigma implementations in hospitals, there has been little empirical evidence that goes beyond descriptive case studies to address the current status and the effectiveness of the implementations. Purpose The aim of this study was to explore existing patterns of Lean and Six Sigma implementation in U.S. hospitals and compare the performance of the different patterns. Methodology/approach We collected data from 215 U.S. hospitals via a survey that includes measurement items developed from related literature. Using the cross-sectional data, we conducted a cluster analysis, followed by t tests, chi-square tests, and regression analyses for cluster verification. Results The cluster analysis identifies two clusters, a Moderate Six Sigma group and a Lean Six Sigma group. Results show that the Lean Six Sigma group outperforms the Moderate Six Sigma group across many performance dimensions: responsiveness capability, patient safety, and possibly cost saving. In addition, the Lean Six Sigma group tends to be composed of larger, private teaching hospitals located in more urban areas, and they employ more resources for quality improvement. Conclusion Our research contributes to the quality management literature by supporting the possible complementary relationship between Lean and Six Sigma in hospitals. Practice implications Our study encourages practitioners and managers to pay more attention to Lean implementation. Although Lean seems to be conducted in a limited fashion in many hospitals, it should be expanded and combined with Six Sigma for better results.
