Six Sigma Methodology

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.

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 – 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.

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.

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 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.

Purpose – The purpose of this paper is to present a case study on the use of Lean Six Sigma principles and tools to study the improvement in design and construction services at a university. The quality of facilities services at universities has been criticized by users calling for improvement. Design/methodology/approach – Quality of facilities services at universities has been criticized by users calling for improvement. The purpose of this paper is to present a case study on using Lean Six Sigma principles and tools to study improving design and construction services at a university. Findings – It was found that non-value-added general improvement review form (GIRF) process steps involving revisions and rework for the design and construction result in time delays, cost increases and quality deficiencies and render cost estimates unreliable; these are unnecessary and should be minimized or eliminated. It was additionally noted that administrative reviews and approvals embedded in GIRF processes slow down work flow, leading to similar problems. Because such steps may be needed for institutional reasons precluding elimination, it was recommended that efforts be directed toward reducing their durations and costs. Overall, the Lean Six Sigma methodology proved to be successful for the intended purpose. Originality/value – Although universities are aware of their facilities services’ quality issues and have been addressing them, no published information is available on how to systematically evaluate and improve such services to increase customer satisfaction. This paper aims at filling this gap.
