“…Likewise Enoch (2013), which found a low level of adoption and high rate of fault and design waste with unending rework among Nigerian manufacturing firms. more so, a study by Reddy and Reddy (2010) indicated that in spite the fact that the bearing manufacturing company in Hyderabad fully aware of the effectiveness of Six Sigma in attaining operational accuracy, the level of adoption of Six Sigma is below average. However, a study by Obaidullah (2005) indicated that manufacturing firms in the UK are yet to fully adopt Six Sigma after a period of 3 decades of introduction, while only 40% of the staff have been trained in line with Six Sigma process in the most organization.…”

“…The study recommended that CEOs of MSMEs should start training on Lean Six Sigma to allow them to provide strong leadership. The study by Reddy and Reddy (2010) titled: "Process improvement using Six Sigmaa case study in the small-scale industry." The study was aimed at process improving using Six Sigma at bearing manufacturing facility in Hyderabad.…”

“…Interestingly, in today's business world, Six Sigma has been successfully applied in finance, healthcare, banking and many other business processes (Natarajan and 27 Morse, 2009). In spite of wider range of application of Six Sigma, evidence from studies such as (Obaidullah, 2005, Reddy & Reddy, 2010and Moosaa & Sajid, 2010 has shown that most firms are not fully implementing Six Sigma, while most are partner other techniques such as TQM and SMPs with Six Sigma as a result, the desired outcome is falling below expectation. Evidence from studies on the performance of manufacturing firms in most African countries manufacturing firms have shown that the adoption of Six Sigma has been in practice for more than two decades, Alexander, Jacqueline and Jacqueline (2015) argued that most firms in Eastern part of Africa shifted from TQM to Six Sigma after identified the performance of six sigma firms in the advanced countries.…”

The effect of Six Sigma on Performance of MSF's in SouthEast Nigeria. The main objective is to determine the effects of Six Sigma on the performance of MSF's in SouthEast , Nigeria. While others are to: determine the extent at which process defines influence the customers' patronage of their product, determine the extent at which process measurement influences product positioning and determine the extent at which improvement on production processes influence customers retention. The result shows that process definition practice among MSF's significantly influenced customers' patronage, process measurement among MSF's was found significant influencing positioning and production improvement significantly influenced customer retention among MSF's in SouthEast Nigeria. The study concluded adoption of Six Sigma practices positively influences the performance of the MSF's in SouthEast Nigeria.

PurposeThe purpose of this paper is to explore Six Sigma practices in a casting industry, that could improve the green sand casting process in a foundry by reducing the casting defects. The goal was to determine which variables influenced this evolution and the relative weight of critical success factors as the methodology developed.Design/methodology/approachThe DMAIC (Define, Measurement, Analyze, Improve, and Control)‐based Six Sigma approach is implemented to improve the green sand casting process and has made the process more robust to quality variations. Analysis of various critical process parameters of the melt shop is also carried out with the help of Taguchi's method of experimental design.FindingsThe proposed techniques optimized control factors, resulting in superior quality and stability of the green sand castings process, which contributes to minimizing the casting defects and improving the Sigma level of the industry.Research limitations/implicationsThis study was carried out with some boundaries such as the number of castings of differential housings, available resources, time constraints, etc.Practical implicationsThis paper is most valuable for the foundry industry, which can avail the direct benefit of Six Sigma results from the reduction in the number of defects due to improved casting processes and dispels the myths concerning the hardly ever use of Six Sigma in the casting industry.Originality/valueThe novelty of the paper lies in conducting a comparative study on the performance of a Six Sigma project. The paper will be valuable for quality professionals and management personnel in the casting industry.

“…Six Sigma is a data driven process improvement approach that uses both the scientific and the statistical methods to achieve bottom-line results. Motorola coined the concept of Six Sigma and General Electric popularised it (Reddy and Reddy, 2010). Six Sigma uses conventional and advance tools of quality management to reduce process variation.…”

Six Sigma is a proven strategy for creating maximum value for its customers, employees and shareholders. Still, it is noticed that a lot of recourses are normally consumed to deploy Six Sigma in organisation, which is associated with risk involved in its success. There is a need to review and enhance the tool kit of Six Sigma for making it more effective. Theory of Inventive Problem Solving (TRIZ) plays an important role for this purpose. This paper discusses about tool kit of TRIZ which is used to enhance the success of Six Sigma implementation. An integrated tool kit has been developed and tested during a live Six Sigma project in a manufacturing industry. A questionnaire-based survey has been conducted to validate the benefits of this integrated tool kit. It has been observed that users of Six Sigma are not very much familiar with TRIZ tools. It is also established that TRIZ can improve the effectiveness and efficiency of Six Sigma tools. This paper is of great value to various industries, researchers, managers and engineers involved in Six Sigma implementation/research. This paper provides insight into the actual benefits of deployment of TRIZ in Six Sigma projects in a manufacturing environment.
