Purpose – The purpose of this paper is to present a framework and a case that delineates the coordinated use of the socio-economic approach to management (SEAM) and Lean Six Sigma (LSS) to facilitate operational change. Design/methodology/approach – This study uses action research and thematic analysis to explore the augmentation of existing process improvement and organizational assessment methodologies in a production environment. Findings – Organizations are under increasing pressure to improve all aspects of business. Project leaders and consultants often follow popular quantitatively oriented protocols like LSS to evaluate explicit operational processes. Including a qualitatively oriented protocol like SEAM expands the project leader’s capability through greater consideration of implicit organizational issues. This paper presents a case where LSS was complemented by SEAM to assess a process that was entangled with several latent organizational dysfunctions. Practical implications – SEAM and LSS are accepted protocols to facilitate process improvement and organizational change. Pairing the two protocols into a SEAM-LSS model offers the strengths of each approach, while compensating for the limitations of each. The result is a more inclusive change protocol that reduces potential oversights and inefficiencies that could occur if project leaders worked within the purview of only one methodology. Originality/value – This paper uses action research to propose a model to bring qualitative and quantitative methodologies together into a larger complementary framework to use when evaluating organizational problems and opportunities. This paper aims to stimulate discussion and research that would lead to more robust process improvement protocols.

PurposeThe article evaluates the obstacles, lessons learned and managerial implications of deploying Lean Six Sigma (LSS) in a dental college hospital in India.Design/methodology/approachThe work adopts the action research (AR) methodology to establish a case study, which is carried out using the LSS define–measure–analyze–improve–control (DAMIC) approach in a dental college. It uses LSS tools to enhance the productivity and performance of the Conservative Dentistry Department of a dental college and to unravel the obstacles and success factors in applying it to the education and healthcare sector together.FindingsThe root cause for high turn-around time (TAT) is ascertained using LSS tools and techniques. The effective deployment of the solutions to the root causes of variation assists the dental college to reduce the TAT of the Conservative Dentistry process from an average of 63.9 min–36.5 min (i.e. 42.9% improvement), and the process Standard Deviation (SD) was reduced from 2.63 to 2 min. This, in turn, raises the sigma level from 0.48 to 3.23, a noteworthy successful story for this dental college.Research limitations/implicationsWhile the results and recommendations of this research are focused on a single case study, it is to be noted that the case study is carried out with new users of LSS tools and techniques, especially with the assistance of interns. This indicates the applicability of LSS in dental colleges; thus, the adopted modality can be further refined to fit India's education and hospital sector together.Originality/valueThis article explains the implementation of LSS from an aspiring user viewpoint to assist dental colleges and policymakers in improving competitiveness. In addition, the medical education sector can introduce an LSS course in the existing programme to leverage the potential of this methodology to bring synergy and collaborative research between data-based thinking and the medical field based on the findings of this study. The most important contribution of this article is the illustration of the design of experiments (DOE) in the dental college process.

Purpose This paper aims to expand the knowledge about Lean Six Sigma (LSS) implementation in the public sector. By analyzing an LSS improvement initiative in a German municipality, examples of success, barriers and challenges are discussed. A comparison with literature regarding the production and service sectors unfolds similarities and differences. Design/methodology/approach The paper applies the action research method. Especially for the broad field of project management, methods focusing on actual experience from practice have been recommended by many researchers. Findings Implementations of LSS in the public sector seem to be particularly challenging and lengthy. Change and communication management have proved to be the most important aspects to successful acceptance, cooperation and improvement sustainability. In the analyzed cases, the needed volume of data could often not be procured. The applied Six Sigma methodology primarily included the DMAIC project phases as well as selected standard instruments. In contrast, the lean elements of LSS achieved more results and were appreciated by project team members. Originality/value The LSS application in this paper provides insights into practical implementation experience in a municipality, as well as lessons learned. Until now, most research addressed the single application of lean, continuous improvement or Six Sigma. This paper represents the first academic report of a LSS program in a German municipality and underlines the need for scientific support of those initiatives in further municipalities worldwide.

Purpose The purpose of this paper is to utilise the research patterns of the most prolific contributors to Lean and Six Sigma methodologies over a 15-year period to inform the discussion on whether the methodologies should be or are being integrated. Design/methodology/approach Structured searches using keywords were carried out using a single database (SCOPUS) to identify the most prolific contributors to research articles in the areas of Lean, Six Sigma and Lean Six Sigma, and thereafter patterns were analysed in five-year periods between 2000 and 2015. Findings This research demonstrates clear changing and evolving patterns of research activity. Not only is there a clear emergence of research focussed on Lean Six Sigma rather than a single methodology, there are also indications that researchers publish work using different methodologies in response to different challenges. Research limitations/implications The research is restricted to a single database and includes only the 21 most prolific contributors in each five-year period. The analysis is based on the focus of each peer-reviewed paper contributed to. Practical implications This research is intended to support and inform organisations which are developing or running business process improvement approaches by demonstrating the flexibility of Lean and Sigma, and evidencing that researchers work across different approaches and combine them when appropriate. Originality/value This paper provides a unique perspective on the debate for the integration of Lean and Six Sigma by looking at the patterns of work of researchers themselves to identify whether the focus of research has in fact moved on from exclusively lean or Six Sigma to more integrated approaches as has been argued in individual pieces of research.

PurposeThe primary aim of this article is to ascertain the modalities of leveraging Lean Six Sigma (LSS) for Industry 4.0 (I4.0) with special reference to the process industries. Moreover, it intends to determine the applicability of simulation-based LSS in the automation of the mineral water industry, with special emphasis on the robust design of the control system to improve productivity and performance.Design/methodology/approachThis study adopts the action research methodology, which is exploratory in nature along with the DMAIC (define-measure-analyze-improve-control) approach to systematically unearth the root causes and to develop robust solutions. The MATLAB simulation software and Minitab statistical software are effectively utilized to draw the inferences.FindingsThe root causes of critical to quality characteristic (CTQ) and variation in purity level of water are addressed through the simulation-based LSS approach. All the process parameters and noise parameters of the reverse osmosis (RO) process are optimized to reduce the errors and to improve the purity of the water. The project shows substantial improvement in the sigma rating from 1.14 to 3.88 due to data-based analysis and actions in the process. Eventually, this assists the management to realize an annual saving of 20% of its production and overhead costs. This study indicates that LSS can be applicable even in the advent of I4.0 by reinforcing the existing approach and embracing data analysis through simulation.Research limitations/implicationsThe limitation of this research is that the inference is drawn based on a single case study confined to process industry automation. Having said that, the methodology deployed, scientific information related to optimization, and technical base established can be generalized.Originality/valueThis article is the first of its kind in establishing the integration of simulation, LSS, and I4.0 with special reference to automation in the process industry. It also delineates the case study in a phase-wise manner to explore the applicability and relevance of LSS with I4.0. The study is archetype in enabling LSS to a new era, and can act as a benchmark document for academicians, researchers, and practitioners for further research and development.

The Impact

Purpose The purpose of this study is to reflect upon the ramifications of two decades of Lean Six Sigma implementations in Dutch healthcare institutions in the light of the current COVID-19 pandemic. Design/methodology/approach The authors provide an evaluation of the impact that Lean Six Sigma implementations have had on the ability of Dutch healthcare institutions to respond adequately to healthcare needs during the COVID-19 crisis. Findings Process improvement in healthcare has had a tendency to cut capacity and flexibility which are needed to deal with excessive demand shocks, such as during a pandemic. The main reason for this failure seems to be an overly strong focus on cost reduction instigated by Lean Six Sigma during stable times. Research limitations/implications Besides the research method being an inferential procedure, the research focuses on the Netherlands and so the generalizability might be limited. However, using Lean Six Sigma to improve healthcare processes has found broad acceptance, so the implications may well carry over to other countries. Practical implications The authors call for a more comprehensive approach of process improvement within healthcare that takes flexibility and buffering in anticipation of excess variability and disruption into greater account. Therefore, this study provides a new perspective on how and to which aim Lean Six Sigma should be applied in healthcare. Originality/value An assessment is given of the impact of Lean Six Sigma implementations on the ability to respond to the COVID-19 crisis. This is done by identifying the focus points of improvement projects and considering the impact on the resilience of healthcare operations.

The Impact

Purpose Process improvement initiatives, such as Lean, Six Sigma and Lean Six Sigma, typically have common characteristics that are carried through projects. Whilst a project’s performance is an important determinant of the successful implementation of continuous improvement (CI) initiatives, its failure can undermine the impact of any CI initiative on business performance. As a result, an understanding of the reasons of process improvement project failures is crucial. The purpose of this paper is to present the results of a pilot survey highlighting the most common reasons for process improvement project failures. Design/methodology/approach This paper presents a pilot survey of 42 Brazilian manufacturing specialists who have been involved in process improvement projects. The participants of this survey were Six Sigma Master Black Belts, Black Belts, Green Belts and Six Sigma champions from manufacturing companies in Brazil. The survey questionnaire was piloted with five experts in the field in order to ensure that the questions were valid and technically sound. Findings The execution of Six Sigma projects in organizations results in a moderate rate of project failures. These failures can cost organizations several millions of dollars especially within the context of larger organizations. The main reasons for project failure, as cited by the specialists include: resistance to change, lack of commitment and support from top management and incompetent teams. Research limitations/implications The authors report the findings from a pilot survey having a limited sample size. Moreover, the data have been collected from one country and primarily from large manufacturing companies. Originality/value To the best of the authors’ knowledge, this is the first empirical study looking into the reasons for process improvement project failures. The authors argue that if the top reasons for such failures are understood, a framework can be developed in the future that can mitigate the chance of project failures during project execution. This could potentially lead to significant savings to the bottom-line of many organizations.

Purpose – Lean and Six Sigma are continuous improvement methodologies that have garnered international fame for improving manufacturing and service processes. Increasingly these methodologies are demonstrating their power to also improve healthcare processes. The purpose of this paper is to discuss a case study for the application of Lean and Six Sigma tools in the reduction of turnaround time (TAT) for Emergency Department (ED) specimens. This application of the scientific methodologies uncovered opportunities to improve the entire ED to lab system for the specimens. Design/methodology/approach – This case study provides details on the completion of a Lean Six Sigma project in a 1,000 bed tertiary care teaching hospital. Six Sigma’s Define, Measure, Analyze, Improve, and Control methodology is very similar to good medical practice: first, relevant information is obtained and assembled; second, a careful and thorough diagnosis is completed; third, a treatment is proposed and implemented; and fourth, checks are made to determine if the treatment was effective. Lean’s primary goal is to do more with less work and waste. The Lean methodology was used to identify and eliminate waste through rapid implementation of change. Findings – The initial focus of this project was the reduction of turn-around-times for ED specimens. However, the results led to better processes for both the internal and external customers of this and other processes. The project results included: a 50 percent decrease in vials used for testing, a 50 percent decrease in unused or extra specimens, a 90 percent decrease in ED specimens without orders, a 30 percent decrease in complete blood count analysis (CBCA) Median TAT, a 50 percent decrease in CBCA TAT Variation, a 10 percent decrease in Troponin TAT Variation, a 18.2 percent decrease in URPN TAT Variation, and a 2-5 minute decrease in ED registered nurses rainbow draw time. Practical implications – This case study demonstrated how the quantitative power of Six Sigma and the speed of Lean worked in harmony to improve the blood draw process for a 1,000 bed tertiary care teaching hospital. The blood draw process is a standard process used in hospitals to collect blood chemistry and hematology information for clinicians. The methods used in this case study demonstrated valuable and practical applications of process improvement methodologies that can be used for any hospital process and/or service environment. Originality/value – While this is not the first case study that has demonstrated the use of continuous process improvement methodologies to improve a hospital process, it is unique in the way in which it utilizes the strength of the project focussed approach that adheres more to the structure and rigor of Six Sigma and relied less on the speed of lean. Additionally, the application of these methodologies in healthcare is emerging research.
