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 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 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.

PurposeTo empirically examine the usefulness and value of supply chain mapping (SC mapping), which has been neglected despite its importance in research and practice.Design/methodology/approachBased on three combined theoretical perspectives, we conducted a case study on a car manufacturer's managers mapping their downstream supply chain (SC). We conducted semi-structured interviews and a mapping exercise with them, followed by a focus group.FindingsWe find differences between individual and corporate SC maps and between how managers define the outbound SC, the SC map they draw and what they say when mapping. The three theoretical perspectives allow us to enrich SC mapping thinking. We focus on boundary objects to formulate propositions. SC mapping and maps are discussed with respect to contemporary SCs and SCM.Research limitations/implicationsBased on a single case study on one firm's outbound SC. Research could be expanded to the company's external partners and follow the development and use of maps in real time.Practical implicationsHighlights the usefulness and difficulties of SC mapping, for individuals and organisations. For the company, it opens avenues for further development and use of SC mapping to improve inter-functional and inter-organisational collaboration.Social implicationsConfirms the need for SC mapping competences in SCM and consequently the usefulness of teaching SC mapping courses in logistics and SCM programs.Originality/valueHighlights the usefulness of SC mapping and rekindles interest in SC mapping and maps in SCM. Introduces boundary objects into SCM research.

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.

PurposeThis paper aims to depict the practical execution of the problem-solving structure provided by the define, measure, analyze, improve and control (DMAIC) framework in combination with the analytical power provided by process mining capabilities, to improve the supply chain quality of a health-care provider. Design/methodology/approachPrior to the study, a literature review was conducted to identify existing frameworks combining six sigma with process mining. The authors use a descriptive case study approach to explain how the two methodologies blend across the different phases of DMAIC in a health-care setting. FindingsThis case study describes how analyzing data extracted from core information systems has significant value to improvement initiatives when complemented by traditional quality methods. By intersecting process mining techniques with lean six sigma tools, the researchers found 65% of orders not complying with the target ordering time and 200 redundant purchases with high operational costs. Research limitations/implicationsBy depicting how the two methodologies can be intertwined, this paper complements existing research by presenting it as a viable quality improvement approach. Practical implicationsThis paper provides insights for six sigma and process mining practitioners on the benefits of combining both methodologies within the DMAIC structure. Implementing this blended approach can bring visibility to operations and accelerate process improvement initiatives. Originality/valueThe prime value of this paper lies in the integration of traditional six sigma methods with process mining as a technological approach in a health-care context, going beyond existing research, which, to the best of the knowledge, lacks descriptive case studies.

Purpose – The purpose of this paper is to assess the current use being made of the sustainability message within business improvement activity and project justification within individual businesses. Design/methodology/approach – This is a reflective paper that looks at an illustrative case study against the wider perspectives of Lean Six Sigma (LSS) implementation, market orientation and business improvement initiatives in general. Findings – The piece discusses the gains derived from the LSS projects and identifies gaps in potential benefits in particular the paper questions how well any potential marketing messages were exploited by the organisation. The findings critically evaluates the impact that marketing function involvement could have in helping to promote the wider productivity message and its contribution to the wider corporate social responsibility (CSR) strategy for the organisation. The document also suggests how the company could leverage internally focused projects to adopt a companywide marketing orientation and use such leverage to support future LSS project selection and justification. Research limitations/implications – The observations are limited to a single case study, although tempered by the authors’ wider experience. Further empirical research is required to validate the observations and conclusions. Practical implications – The proposed approach to future improvement initiatives can help to increase the wider productivity message and assist organisations to exploit their internal projects in external communications and wider CSR strategy. Originality/value – The paper proposes an approach that can be used to widen organisational involvement in improvement initiatives allowing future project justification to be less internally cost focused, more holistic with a focus on customer voice.

Purpose – The purpose of this paper is to study the scope of Lean Six Sigma (LSS) strategy and to explore its successful deployment in the Indian healthcare sector. Design/methodology/approach – The research reported in this paper is based on a case study carried out using the LSS DMAIC (Define-Measure-Analyze-Control) approach and its application in improving the registration process in the Health Information Department (HID) of a Medical College hospital in India. Findings – The study describes improvements in the HID through the power of LSS. Cycle time of the process was reduced from three to 1.5 minutes and the SD was reduced to 21.2 from 61 seconds. The project has shown a 94 per cent reduction in patients’ average waiting time. The study also reported a 91 per cent reduction in queue length and 48 per cent reduction in percentage of scheduled utilization of staff for the process. Research limitations/implications – The paper is based on a single case study executed in a hospital and hence there is limitation in generalizing the specific results from the study. But the approach adopted and the learning from this study can be generalized. The study is of use to healthcare practitioners seeking to implement or develop LSS further in their organizations. Originality/value – Although LSS being extremely successful in the last two decades, the application of LSS to the healthcare industry in general and HID in particular has been limited. This study illustrates how its application can improve the performance of the process and thus productivity in the department.

Purpose The purpose of this paper is to add understanding to whether the supply chain (SC) of ancient grains, einkorn in particular, may activate the virtuous mechanisms that enable pursuing a new equilibrium based on relationships and joint interests. Design/methodology/approach This study adopts the single case study as a methodological approach. More precisely, it focusses on the SC of ancient grains in Piedmont (Italy) examining in detail Mulino Marino. Interviews with the management of this single player and to some farmers’ local associations were carried out. Findings The einkorn SC in Piedmont Region is an interesting case of short, local and direct SC because it aims at delivering a product that is more sustainable in terms of production, nutritional values and properties. In addition, this study confirms previous studies according to which for an effective supply chain management (SCM) it is important to implement the following conditions: the right equilibrium among SC players’ physiologically conflicting interests, players’ integration and transparent information among all the SC stakeholders, including final consumers. Practical implications The study offers implications for food managers involved in the (short) SCM. Originality/value Elements of originality can be identified in this research to the extension of studies on SCM in the ancient grains industry.

Purpose The aim of this paper is to characterize how innovation may happen through cross-functional teams (CFT) in an organization of the public sector. Design/methodology/approach A case study helped to characterize several behavior patterns, team structures and respective links with generating innovation in internal processes and public answering contexts. Findings The results highlight that formal-temporary teams present a higher capacity to generate incremental innovation in products, whereas permanent-informal teams have a higher capacity to generate innovation in the internal processes and public answering contexts. Research limitations/implications The limitations of this research relate to the fact that this is a single case study, and although it is an important case to examine innovation and CFTs, by its very nature, it is not possible to extend and generalize the obtained data to other organizations. The evaluation of its propositions was merely qualitative, and future research is needed to validate its characteristics. Practical implications Several settings of CFTs are presented, as well as their ability to generate different types of innovation, such as the computerization of documents, petitions and papers, which decreases the time to answer the taxpayer. Moreover, CFTs can help to create products, such as computer programs that can be used not only locally but also in several public organizations related to tax management. Originality/value The field research provides the perceptions of the respondents regarding CFT characteristics that can lead to specific types of innovation, as well as the types of products or services that can be generated by these processes.
