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 examine a contextualized local government case study of the application of Lean Six Sigma (LSS) in conjunction with the Australian Business Excellence Framework (ABEF) to highlight the importance of a good strategic fit between LSS and organizational objectives before implementation. Design/methodology/approach A local government council is used in a case study-based approach. Organizational artefacts and documents were used for data collection in conjunction with interviews from senior executives within the organization. Findings Results indicate that when used in conjunction with the ABEF, LSS provides focus on organizational learning practices embedded within the implementation of continuous improvement. Research limitations/implications The purpose of this paper is to contribute to discourse regarding the effective application and implementation of LLS in local government. Practical implications LSS tools and techniques are known to local government, but are applied in isolation of the overarching LSS framework. This paper emphasizes the importance of comprehensive implementation of these tools, guided by the inclusion of an external contextualized framework (ABEF) in conjunction with the LSS to achieve sustainable continuous improvement. Originality/value Business excellence frameworks are widely used in the public sector as a reference/means for improvement. This paper highlights the importance of LSS in operationalizing strategic direction provided by such frameworks and providing the focus on learning practices critical for sustainable improvements.

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 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.

The Impact

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 Using Lean Six Sigma (LSS) implementation literature as an organising framework, the purpose of this paper is to explore the initial steps in a continuous improvement (CI) journey taken by an Irish university in order to identify the motivations, highlight key challenges and considers the capabilities required to initiate and sustain a CI programme. Design/methodology/approach This study focusses on one case organisation. A participative approach is adopted to learn from the initial steps taken in the establishment of a CI programme. Given this approach, the researchers had access to all documents and related archives associated with this initiative. Hence an iterative learning approach is adopted with the analysis of data from the first 12-month plan informing the next planning and implementation phase. Findings This paper provides a reflective account of why and how a university went about commencing a CI programme. The motivation to establish the CI programme not only reflects the current fiscal environment but also one characterised by a need to respond to a number of increasingly demanding stakeholders. The insights gained highlight the importance of alignment with strategy, role of specialists and use of a structured method informed by a LSS approach. Of particular note is the role of expertise, both internal and external, and within this context the interplay between a formal top-down approach and the coming together enthusiast staff, some of whom had CI experience from previous employment. A number of practical implications were identified as a result of the study including the key role of the project sponsor; the criticality of an understanding of the fundamental LSS concepts and tools and techniques by management; and the key role played by improvement specialists. Originality/value While in recent times a strong case for the application of LSS in HEIs has been made, there is a paucity of case studies based on the reflective practice in the field. This paper is novel in that it aims to address this and contribute to an emerging body of CI literature in the HEI area.

Learning Points

Purpose This paper is based on a single case study carried out as part of a change programme but is used as a reflective tool to draw on some of the wider organisational learning which can be considered when implementing, reviewing or re-energise a Lean Six Sigma (LSS) Programme. The paper aims to discuss this issue. Design/methodology/approach A case study approach has been used and referenced throughout the paper with references to literature to support the wider learning points drawn which are then applied to any continuous improvement (CI) programmes. Findings The paper presents a range of learning points which are drawn from a successful deployment of LSS within a change project carried out as part of an overall programme in Scottish policing services. Research limitations/implications The points are drawn from a single case study which was deployed within a wider change programme and is supported by wider literature but is used as a vehicle for informing strategic considerations within an organisation. Originality/value This case study is drawn from policing services in the public sector which alone is an area that has not been significantly studied. It is used to explore wider implications in terms of strategic alignment, organisational performance and project management and presents the argument that the design of a CI programme is much wider than the implementation of LSS itself.

Purpose The purpose of this paper is to use a practical case study approach to demonstrate the power to use lean Six Sigma (LSS) to improve service process in a higher education institution (HEI). The paper also illustrated the barriers and challenges met and lessons learnt for the LSS adoption in this HEI. Design/methodology/approach Prior to the study, extensive literature review was conducted to understand various aspects of LSS in HE industry. The authors use a single descriptive case study as methodology to explain how DMAIC was applied within a HEI environment. Findings In this LSS case study, the team found HEI service process contains a large human behavior component, which dramatically increases the unpredictability of the entire service delivery process and increases the complexity of the process and the ability of the improvement team to identify the root cause. This case study demonstrates the numerous challenges will occur in working with the intangible factors that are both hard to recognize, quantify and rarely tracked by organization. Practical implications During the research, the pre-award service process was studied, data were recorded and various statistical tool and techniques were used to discover and resolve the root cause. The lessons learnt of the LSS adoption in this service process in HEI and the problems encountered were all recorded in this study, which will be helpful for future research in HEI industry. Originality/value From the literature review, LSS has been widely adopted in manufacturing industry, increased adoption in service, but there has been limited academic research about the implementation in nonprofit, service sectors, particular to higher education industry. The major benefit of implementation LSS in both manufacturing and service is considerable improvement to the bottom line. However, in this HEI case study, it has opened up the direction to implement LSS to better serve your customer as ultimate mission instead of financial gains.

Logistics Services

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.
