Customer satisfaction and loyalty are dependent on the consistency of an organization's performance, but not the average performance. For example, Coca-Cola does not provide the best taste drink in the world. However, due to its super-consistent product quality, it becomes one of the most successful organizations in the world. Therefore, every organization must control its product deviation and maintain it at a minimum level, in order to achieve excellence.
SIX SIGMA is a data-based improvement methodology. Through effective analysis of data by using appropriate analysis tools, a closed-loop improvement mechanism is established. The organization can then achieve excellence through running a series of improvement projects.
SIX SIGMA can be interpreted as achieving 99.9997% conformance in critical processes. Besides it, SIX SIGMA also focuses on the value derived from such a figure. SIX SIGMA aims on not only meeting customer requirements, but also creating the maximum value and the minimum costs between the producer and consumers.
SIX SIGMA achieves excellence through
completing projects. It emphasizes on measurements. Traditional quality improvement
methodologies emphasize on awareness and attitudes. It is difficult to judge
whether they are implemented successfully or not.
Through using SIX SIGMA, it is easy for an organization to create shared objectives
among the people. SIX SIGMA aims on improving the capability of predicting process
result. By using appropriate statistical tools, the causal relationships between
process results and critical factors are studied carefully, thus solving problems
completely.
