how to use lean six Sigma Methodology to improve service process in higher education a case study
International Journal of Lean Six Sigma, 2019Co-Authors: Chad Laux, Jiju AntonyAbstract: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.,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.,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.,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.,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.

Reducing Patient Waiting Time in Outpatient Department Using Lean Six Sigma Methodology
Quality and Reliability Engineering International, 2013Co-Authors: E.v. Gijo, Jiju AntonyAbstract:This article addresses the issue of longer patient waiting time in the outpatient department (OPD) of a super specialty hospital attached to a manufacturing company in India. Due to longer waiting times at OPD, employees need to be away from the workplace for a longer duration. This problem was addressed through the Lean Six Sigma (LSS) Methodology. The process, starting from registration of a patient to dispensing of medicine, was included in the project. The non-value added steps in the process were identified, and actions were initiated. A cause and effect diagram was prepared for high patient waiting time, and causes were validated with the help of data collected from the process. Statistical tools such as Kruskal–Wallis test, Box – Cox transformation, Control charts, normality test, etc., were used within the LSS Methodology not only to identify the causes but also to sustain the improvements. As a result of this project, the average waiting time reduced from 57 min to 24.5 min and the standard deviation was reduced to 9.27 from 31.15 min. This will help the hospital to serve patients better and faster, which, in turn, will lead to a reduction in delay of treatment and a faster recovery of patients. The productivity loss due to absenteeism of employees from the workplace could be reduced. Generally, in an Indian health care scenario, most of the activities were dependent on individual doctors rather than processes. This project has helped the clinicians and the hospital management to identify the weak areas in the process for improvement. Because of the implemented solutions, understanding the history of past treatments and medications of the patients was easy for the doctors. Also, the practical validity of deploying LSS in a healthcare scenario was justified with this study. Copyright © 2013 John Wiley & Sons, Ltd.

an application of six Sigma to reduce waste
Quality and Reliability Engineering International, 2005Co-Authors: Jiju AntonyAbstract:Six Sigma has been considered a powerful business strategy that employs a well-structured continuous improvement Methodology to reduce process variability and drive out waste within the business processes using effective application of statistical tools and techniques. Although there is a wider acceptance of Six Sigma in many organizations today, there appears to be virtually no in-depth case study of Six Sigma in the existing literature. This involves how the Six Sigma Methodology has been used, how Six Sigma tools and techniques have been applied and how the benefits have been generated. This paper presents a case study illustrating the effective use of Six Sigma to reduce waste in a coating process. It describes in detail how the project was selected and how the Six Sigma Methodology was applied. It also shows how various tools and techniques within the Six Sigma Methodology have been employed to achieve substantial financial benefits.

a unique assessment of co2 removal plant corrosion six Sigma and swiss cheese could these management frameworks assist with root cause identification and corrosion mitigation of hot potassium carbonate acid gas removal plants
Corrosion, 2007Co-Authors: S J Harjac, Andrej Atrens, H MossAbstract:A review of the operational history of Hot Potassium Carbonate (HPC) acid gas removal plants has shown that corrosion incidents have been attributed to a number of events and that corrosion problems have been long standing. Usually a recalcitrant long-standing problem can be identified as occurring at a specific time and be linked with a change to process / plant operating conditions and hence it is beneficial to widely review the operating history of a process. Such an approach may be supported by the framework of the Six Sigma Methodology. This paper reviews the plant-based reports and findings, operating history and inspection findings for Absorber Towers in a HPC plant in Australia using the six Sigma Methodology. Suggestions are given for further research to refine understanding of these corrosion incidents in HPC plants. Furthermore, this paper includes an overview of the Six Sigma Methodology and explores whether the Six Sigma Methodology, traditionally used to solve problems in the manufacturing and continuous process industries, can be used as a tool to assist plants to overcome corrosion problems. Organisational aspects were identified as critical to manage corrosion.

efficiency improvement on the multicrystalline silicon wafer through six Sigma Methodology
International Journal of Sustainable Energy, 2012Co-Authors: S Saravanan, Meera Mahadevan, Prakash Suratkar, E.v. GijoAbstract:Crystalline silicon solar cell technology continues to be dominant in the photovoltaic (PV) technology due to its novel process flow and the clear understanding of the material. Being a mature material-based technology; on the one hand, it has quite a few opportunities for improvement, on the other hand, the expansion of solar energy should depend on this technology. Due to increase in the global energy consumption and high competition level in the market, it has become necessary to show significant improvement in the performance of the present process/product. The demand for high efficiency solar cells at low costs with shorter cycle times forced the manufacturing industries to improve their processes by applying systematic methodologies such as Six Sigma. This paper illustrates the importance of anti-reflective coatings (ARCs) on the silicon solar cell processes and the successful implementation of Six Sigma to improve the efficiency of the silicon solar cells. The different phases of the Six Sigma DMAI...
