The DMAIC project methodology has five phases: This methodology is used to enhance an existing business process. It specifies a data-driven quality strategy for improving processes. Six Sigma projects follow two project methodologies: Six Sigma involving a lot of training depending on the role of an individual in the Quality Management team. Teamwork Approach to Quality Management: The Six Sigma process requires organizations to get organized when it comes to controlling and improving quality.The quality improvement and control standards are based on specific customer requirements. Customer Focus: The customer focus is fundamental to the Six Sigma approach.The process is flexed to suits the requirements and conditions in which the projects are operating to get the best results. Project and Objective-Based Focus: The Six Sigma process is implemented for an organization's project tailored to its specification and requirements.This accentuates essential elements of the Six Sigma that is a fact and data-based. Fact and Data-Based Approach: The statistical and methodical aspect of Six Sigma shows the scientific basis of the technique.The alternative method DMADV stands for Design-Measure- Analyze-Design-Verify. DMAIC is an acronym for Design-Measure- Analyze-Improve-Control. Methodical Approach: The Six Sigma is not a merely quality improvement strategy in theory, as it features a well defined systematic approach of application in DMAIC and DMADV which can be used to improve the quality of production.Standard Deviation is used to measure variance, which is an essential tool for measuring non-conformance as far as the quality of output is concerned. Statistical Quality Control: Six Sigma is derived from the Greek Letter σ (Sigma) from the Greek alphabet, which is used to denote Standard Deviation in statistics.The Characteristics of Six Sigma are as follows: Six Sigma was adopted by Bob Galvin, the CEO of Motorola in 1986 and registered as a Motorola Trademark on December 28, 1993, then it became a quality leader. ![]() This was obtained by improving management techniques. In the 1980s, Motorola was developing Quasar televisions which were famous, but the time there was lots of defects which came up on that due to picture quality and sound variations.īy using the same raw material, machinery and workforce a Japanese form took over Quasar television production, and within a few months, they produce Quasar TV's sets which have fewer errors. It was introduced by Engineer Sir Bill Smith while working at Motorola in 1986. Six-Sigma is a set of methods and tools for process improvement. A six sigma method is one in which 99.99966% of all the opportunities to produce some features of a component are statistically expected to be free of defects ( 3.4 defective features per million opportunities). The maturity of a manufacturing process can be defined by a sigma rating indicating its percentage of defect-free products it creates. Six Sigma is the process of improving the quality of the output by identifying and eliminating the cause of defects and reduce variability in manufacturing and business processes.
