The roots of Six Sigma as a measurement standard can be traced back to Carl Friedrich Gauss (1777-1855) who introduced the concept of the normal curve. First and foremost measuring the current variation is of utmost importance. A team has to collect data on the current process that is being performed. Six Sigma is a disciplined, data-driven approach and methodology for eliminating defects (driving toward six standard deviations between the mean and the nearest specification limit) in any process -- from manufacturing to transactional and from product to service. Leaders have to identify and then address the issue. It uses data collated to improve the process, reduce/ eliminate mistakes and increase sigma rating. Six Sigma is ---•“Six Sigma is shorthand for a discipline that allows any business to design, improve and manage its processes so that they perform at their highest possible levels.

In the 1920s, Walter Shewhart suggested that three sigma from the mean indicates a critical point. This six sigma technique is also known as potential failure and effects analysis or Failure Modes, Effects and Criticality Analysis (FMECA). The Six Sigma DMAIC approach is typically used to improve an … Brainstorming is essential for generating information for other six sigma techniques like 5Why, FMEA, Fault Tree Analysis and the likes. In statistics, sigma is used as a symbol to represent standard deviation from the mean. And in the end, results are obtained as per expectations. It is used to detect likely errors that might occur in a product, service, process or design. Besides, defects result in waste. The goal of any organization is to streamline its processes, thereby maximizing resources to their fullest extent.
