PurposeThe paper aims to investigate the pros and cons of having a standard for lean six sigma developed in 2015. The study follows up on a previous study by Antony et al. (2021) in more depth and aims to provide a more detailed investigation of various aspects of the standard.Design/methodology/approachA sequential mixed methodology was utilised by interviewing a panel of leading academics and practitioners familiar with lean six sigma followed by distributing a survey questionnaire to continuous improvement and operational excellence (OPEX) personnel.FindingsThe findings indicate that continuous improvement and OPEX professionals have conflicting views of International Standards Organisation (ISO) 18404. A majority of the participants of the qualitative study suggested, whilst supporting the requirement for a lean sigma standard, voiced concerns about the auditability of the standard and whether it is currently “fit for purpose” and proposed that it needs to be revised. Within the quantitative survey, 42% had never heard of the standard, and of the 58% who had heard of it, 90% had read it. Just 10% stated that they had or would apply the standard within their organisations. Just fewer than 50% felt that the standard was fit for purpose which suggests for further refinements of the standard in the future. Finally, 85% of respondents of the quantitative survey suggested for the revision of the standard whilst just 15% felt it should be removed.Research limitations/implicationsOther than a previous study by Antony et al. (2021), implementation of ISO 18404 in organisations and its benefits as well as empirical study looking into the impact of the standard on corporate performance in the literature were limited. An opportunity to review lessons learnt from a case study on the ISO 18404 standard implementation within an organisation would further enhance the research.Originality/valueThe paper provides a valuable resource for organisations to obtain insight into a standard in lean six sigma and whether to implement it or not. Furthermore, the results can form the basis of a case for the future revision of the standard by consolidating and strengthening the findings from the first study with more detailed quantitative and qualitative study.

PurposeThis paper aims to present and summarise the arguments for and against the ISO 18404 standard and the perceived advantages and disadvantages of implementing it.Design/methodology/approachA qualitative interview approach was utilised by interviewing a panel of leading academics and practitioners familiar with Lean Six Sigma.FindingsThe results indicate that Lean Six Sigma professionals have conflicting opinions on ISO 18404. An overwhelming majority of the panel questioned the “quality” of the standard and whether it is “fit for purpose”, while others see the advantages of a common standard in helping continuous improvement deployment.Research limitations/implicationsAs the standard has not been widely adopted, there were limited examples on ISO 18404 discussion in the literature. Much of the current literature focuses on the theoretical application of the standard, with sparse practical examples providing case study deployment. Also, the interviews were short and at a high level. There is an opportunity for further study and analysis. It was difficult to find qualified interviewees who were familiar with the standard. A very real constraint when conducting research into ISO 18404 is to obtain a balanced view of the standard from those who have a vested interest in its continuation and evolution, or not.Originality/valueThe paper provides a resource for people to obtain insight into the value or non-value add of a standard in Lean Six Sigma and the appropriate details of such a standard. These results can form the basis of a case for the implementation of the standard for those organisations currently trying to decide whether to implement it or not.

Purpose The research paper aims to unveil the practical use of Lean Six Sigma and its effectiveness as a business survival strategic tool by a chemical product realization concern, as well as to establish the market and business performance impacts on the manufacturing entity. Design/methodology/approach A case study approach was pursued with a multi-national chemical manufacturing entity in South Africa. A comprehensive literature research was undertaken to establish the contemporary tools used for implementing Lean Six Sigma, and the classification and flow of tools and steps undertaken to ensure the successful and effective application of Lean Six Sigma in a manufacturing organization and the benefits derived. The critical success factors and reasons of ineffective use of tools are reviewed. To ensure that a comprehensive research was conducted which is relevant to the body of knowledge in engineering, recent articles on the application of Lean Six Sigma were selected and reviewed during the progress of the study to add impetus to the relevance of the findings. Findings The research findings were mainly based on the inferences obtained from a chemical product manufacturing concern in South Africa, to distinguish the efficacy and relevance of Lean Six Sigma as strategic business survival tool and imputing strategic resonance to corporate strategy. Research limitations/implications This research was limited to distinguishing Lean Six Sigma as a business survival strategic tool and an ultimate enhancer of market performance for a chemical product manufacturing entity. The implementation and evaluation of the Lean Six Sigma methodology as a business survival strategic and market performance enhancement option for the case study organization was entailed as the corollary of deductive resemblance to similar entities. Practical implications This study enables continuous improvement practitioners to evaluate the Lean and Six Sigma practices. The advantages posed by the simultaneous and optimized application of the two approaches versus individual application were assessed and verified to produce enhanced continuous improvement. This poses further challenges to scholars and academics to pursue further researches on the practicality of applying Lean Six Sigma as a strategic option. Originality/value The paper prompts the efficacy of well publicized methodologies and evaluates their implementation for strategic performance for manufacturing organizations. The practical application, constraints and resultant effects of deploying Lean Six Sigma were reviewed to give impetus to the methodology.

Purpose The purpose of this paper, builds on previous studies that explored the research patterns over 15 years, is to consider the current status of the integration of Lean and Six Sigma. More specifically, this research addresses whether Lean and Six Sigma are stronger together and explores the reasons why Lean researchers and practitioners may be less likely to integrate Six Sigma in their work. Design/methodology/approach The research utilises a survey of 25 established and respected academics and practitioners from 16 countries. The questionnaire is analysed using a direct content approach and coded in NVivo. Findings The findings suggest that challenges may lie in the perception and understanding of statistics as well as short-term rather than long-term focus on improvement. The findings also suggest that academics and practitioners believe that Lean Six Sigma has developed over time and will continue to develop and improve as a methodology rather than being replaced with a new methodology. Research limitations/implications The survey has a sample size of 25, albeit all respondents are established and very experienced practitioners and academics. Practical implications For organisations that are introducing or refreshing their continuous improvement initiatives, this research identifies some of the challenges and provides the opportunity to address them to maximise the opportunities for success and sustainability. Originality/value The value of this paper is that it further addresses the debate over the integration of Lean and Six Sigma for many organisations which still employ Lean alone, but beyond this it explores how they will continue to develop and whether they are a permanent edition to the quality management landscape or a transition to something else.

Purpose The purpose of this paper is to compare the impact of lean six sigma (LSS) implementation carried out in a pharmaceutical unit on the profitability of outpatient and inpatient care before and during the Covid-19 pandemic. Design/method/approach The data were analyzed descriptively to see the development patterns in four periods: before implementation, during the implementation before the pandemic, during the pandemic and during the enforcement of new normal, in general, and by the length of stay (LOS). Findings The inventory purchase in the pharmaceutical unit dramatically decreased after implementation even during the pandemic and new normal wherein the pre-pandemic it decreased by 27%, during the pandemic 29% and in the new normal 37% compared to pre-LSS. The hospital deficit decreased after implementation before the pandemic by 26% and during the pandemic by 10% from the pre-LSS time. However, during the new normal, the deficit increased by 29%, indicating a diminished effect of LSS on the hospital profits. Research limitations/implications This research raised the possible implication that the implementation of LSS needed to be carried out in the entire hospital to have a large effect, especially on the inpatient care and long-term care installations. Originality/value This research provided empirical evidence regarding the effect of the Covid-19 pandemic on the ability of LSS at the unit level to provide efficiency at the unit level and the entire hospital at various levels of LOS.

Purpose This paper aims to contribute to a developing literature on continuous improvement (CI), enabled by Lean Six Sigma (LSS), in higher education institutions (HEIs). It reports on the key learning points arising from the initial steps taken by an Irish university on its CI journey. Design/methodology/approach A case study strategy was adopted following a participatory research approach. This approach supports reflexivity and also provides access to all relevant documentation and staff within the case university. Thematic analysis was supported by data reduction and display techniques. Findings The introduction of a LSS approach rather than a reliance on lean alone introduced a structured methodology (DMAIC) that supported simplification of a number of administrative processes. A number of specific improvements were achieved including: Cycle time and cost reduction; customer or employee satisfaction; and rework and error reduction. The findings support the importance of the Readiness Factors as identified by Antony (2014), with particular insight into the role of senior and middle management, the impact of training and deployment of expertise. Research limitations/implications This paper is based on an ongoing, longitudinal, empirical study of a single case study in Ireland. Originality/value This paper tracks the development of CI in a HEI in a longitudinal manner and adds to the emerging the literature in this area. The paper evaluates the role of management at various levels, analyses the use of LSS tools and techniques and evaluated the role of training and capacity building. Implications for Management are shared including: design and role of training programmes, role of champions at various organisational levels, including key functional areas and sustaining momentum.

PurposeThe aim of this analysis is to review the Indian manufacturing organizations practicing Lean Six Sigma (LSS) tools/techniques with an objective of monitoring the performance of an organization and to develop recommendation for strategies to benchmark organizational operational efficiency.Design/methodology/approachThis study offers insights of the LSS performance measurement aspects of the Indian manufacturing organizations based on Data envelopment analysis (DEA) approach. The five inputs and two outputs are considered on the basis of literature review and discussed with the practitioners.FindingsIn this analysis, the relative efficiency score of 18 Indian manufacturing organizations has been determined in order to assist evaluation of the impact of monetary investment on the outputs. The present analysis not only investigates the optimum level of input variables but also lays down a significant observation that an organization having higher profit and inventory turnover ratio is not necessarily an efficient organization.Practical implicationsThe results assist to determine the best practice units, potential source of inefficiency and deliver beneficial data for the consistent enhancement of the operational efficiency. The DEA results assist managers and decision makers to derive appropriate strategies to enhance their performance with reference to the efficient organization and to regard it as their role model.Originality/valueThis analysis renders a DEA based framework of LSS practicing Indian manufacturing organizations. The framework is unique in terms of its input-outputs variable selection and measurement procedure.
