Successful Deployment of Lean Six Sigma in The Banking Industry

Successful Deployment of Lean Six Sigma in The Banking Industry

The term Six Sigma is originally associated with the statistical aspect regarding a quality performance of a product produced in a manufacturing process. When the variation of the product feature is reduced to such an extent that the upper specification limit (USL) and the lower specification limit (LSL) defined by the design engineer can cover six sigma (6s) of the process standard deviation, and the process average is right aligned the middle point of specifications, the defect rate of the manufacturing process is nearly zero (0.002 parts per million). This situation is shown in Figure 1 (a).  Even when the average of the process is shifted left or right 1.5 sigma, the defect rate remains very small (3.4 parts per million). This case is shown in Figure 2 (b).

The Six Sigma approach has gone far beyond the statistical aspect. It has been more and more recognized as an effective methodology for achieving, sustaining and maximizing business success, owning to cost and shortage of natural resources (such as petroleum), waste disposal, and corresponding environmental problems along with the pressure from government regulations at different levels in recent years. Distinguished from other methods, the Six-Sigma emphasizes the use of facts through data collection and statistical data analysis to identify and solve problems with the ultimate goal of increasing customer satisfaction and business excellence. The increase of manufacturing globalization and competiveness created a need that employees should prepare and have the know-how of Six Sigma. Focusing on one business sector, write a literature review paper about the Six Sigma and the role of training on Six Sigma and business success. The following sections MAY be included:
