The Impact

Purpose Lean Six Sigma (LSS) has been accepted globally across the service sector as a management strategy for achieving process excellence. In the past one decade, the application and success of LSS in services is remarkable across Information Technology (IT) organisations. However academic research has seldom derived implications from this practitioner’s science of improving processes. The purpose of this paper is to feature the application of LSS in the system maintenance department of a manufacturing firm. Design/methodology/approach The research reported in this paper is based on a case study carried out in system maintenance department using the Six Sigma Define-Measure-Analyse-Improve-Control (DMAIC) approach and its application in reducing complaint resolution time. Findings The LSS article presented here highlights a real-world case study of how LSS DMAIC methodology help reduce the complaint resolution time from 12.5 to 8.5 h (~30 per cent improvement) and the corresponding standard deviation from 28 to 17.4 days. This study also has resulted in reducing the turn-around-time of all the core processes in the organisation. The indirect financial savings estimated as a result of this overall impact was around INR2.5m. Research limitations/implications The research was restricted to studying the impact of LSS in one organisation. The validity of the results can be improved by including more organisations and more case studies from the IT support services. Originality/value This could serve as a resource for both practitioners to derive useful implications and to academicians as it contributes to the LSS body of knowledge towards theory testing.

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.

Purpose The purpose of this paper is to explore the fundamental challenges and critical success factors in the development of a Lean Six Sigma (LSS) initiative within a UK higher education institute (HEI). The paper also illustrates examples of the types of projects completed and share some of the key lessons learned as part of the LSS journey. Design/methodology/approach The authors have initially carried out an extensive literature review on the application of LSS in higher education to understand the existing body of work carried out by other scholars in the field. This is followed by presenting a case study explaining how a HEI in the UK has embarked on its LSS journey as a process excellence methodology to improve the efficiency and effectiveness of core and supporting business processes. Findings There has been a clear lack of support and commitment from senior management in the sustainability of LSS within the case study organization. There was a general lack of understanding of the benefits of LSS in the higher education context and there is a lack of knowledge on the use of LSS tools for tackling process efficiency and effectiveness problems across the case study organization. Although a number of LSS projects were executed across finance, administrative, and human resources, as well as IT and library services, no projects were carried out for improving academic processes such as teaching effectiveness. Research limitations/implications As the case study is limited to one higher education institution (HEI), the findings of the study cannot be broadly generalized. Moreover, the paper does not report the findings of any strategic projects as most projects were carried out at the operational level. Originality/value This is possibly one of the first studies reporting project examples of LSS in a HEI. The results of the study can also be used to benchmark with similar studies in other HEIs to understand the impact of certain management practices of LSS.

PurposeThe purpose of this paper is the implementation of Lean Six Sigma (LSS) in a manufacturing small and medium-sized enterprise (SME) in Greece in order to understand the contribution of LSS in its process improvement and to identify the parameters playing a crucial role in LSS adoption by SMEs. The ability to achieve high-effect improvements without cost investment is also examined to cope with low investment margin that is a characteristic of SMEs.Design/methodology/approachThis case study is based on the combination of Define, Measure, Analyze, Improve and Control (DMAIC) phases with the Yin's method for case studies for a complete and efficient implementation and presentation of the project.FindingsThe analysis of this case study revealed that by accomplishing specific critical success factors for the fulfillment of the LSS project, the company attained important benefits by utilizing only the working hours of employees. It was also found that the improvements of LSS projects can be measured using other metrics which can indirectly be translated into monetary terms.Practical implicationsThe paper can be a useful guide of how SMEs can achieve high-impact improvements with low or no investment cost utilizing LSS initiatives in small-scale projects.Originality/valueAccording to the literature, there is a need for more case studies concerning LSS implementation in SMEs. Examples of how low-cost/high-effect improvement initiatives can be implemented have not been adequately presented before. The assessment of the impact of improvement initiatives with non-monetary measures is also innovative.

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 is to elaborate, how the use of a joint-use strategy of Lean and Six Sigma can improve flexibility, robustness, and agility. Telecom manufacturing has been under tremendous change after dot.com bubble burst in the early 2000, and new competition has originated from Asia. Being successful requires now more than before, and joint-use of strategies is one option to survive. Design/methodology/approach – A single case study from a Swedish company operating in the telecom manufacturing was conducted. In particular, a Six Sigma project was followed and analyzed during 2002. However, the outcome of the Six Sigma project has been studied in longitudinal manner until 2014. Findings – The Lean Six Sigma strategy ensures flexible, robust, and efficient processes. However, to make them more agile in order to sustain in today's highly competitive environment, something more is required. This could include staff training, strengthening company culture and collaborating with key partners in the supply chain. Research limitations/implications – This study is limited to large company that usually has a lot of resources and choices where to put the strategic emphasis as well as has level of control of the supply chain operations. The situation could be very different in small and medium-sized companies and thus it may be more difficult to realize the Lean Six Sigma strategy in such environment. On the other hand, the processes in these companies are often less complex. Practical implications – This research provides guidance on how to manage the Lean Six Sigma strategy in order to ensure more flexible, robust, and efficient processes as well as how to perform a Six Sigma project in Lean environment, in a proper manner. Originality/value – This research provides guidance to companies regarding the applicability and properties of the Lean Six Sigma strategy. The paper will also serve as a basis for other companies and industries, on how to survive in difficult times.

Purpose Outsourcing logistical activities have become a widely used approach for firms to avoid high fixed costs and heavy investment requirements and to achieve competitive advantages. Lean six sigma (LSS) has been accepted globally across sectors as a management strategy for achieving process excellence. The purpose of this paper is to feature the application of LSS for improving the supplier selection process (SSP) of outsourced logistics services in a multinational health-care company. Design/methodology/approach This study is based on an action research case study conducted on the SSP of the freight and distribution department in a multinational health-care company. This paper reports on the application of the LSS define-measure-analyze-improve-control (DMAIC) approach for reducing supplier selection lead time. Findings The study features a real-world case study of the LSS DMAIC application to improve the supplier selection process of a large health-care company. The key issues that were identified are lack of information visibility, top-down changes and unclear communication lines. To counteract these three root causes, the lean six sigma techniques that are implemented are the 5S, stakeholder analysis and standard operating procedure. Research limitations/implications This research provided empirical evidence of how practical challenges in SSP can be managed with the use of LSS. It further proposed plausible solutions for reducing and sustaining improved outcomes. As the study is limited to one case, the validity of the results can be improved by including more organisations and more case studies from other similar organisations. Originality/value Research in supplier selection processes rarely links continuous improvement ideology such as LSS to support strategic selection and procurement of logistics services. This paper could serve as a resource for both practitioners to derive useful implications and to academicians as it contributes to the LSS body of knowledge for further theory testing.

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.

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.
