Six Sigma, a methodology developed by Bill Smith at Motorola in the 1990s, is a information-driven approach to quality management that aims to minimize defects and variability in business processes. The methodology has since been adopted by various industries, with many companies using it as a framework for continuous improvement.
At its core, Six Sigma seeks to eliminate defects and improve performance by identifying and addressing the root causes of problems. The methodology is based on the use of quantitative tools and techniques, such as hypothesis testing, Lean Manufacturing consultant regression analysis, and Design of Experiments (DOE), to gather and analyze data.
The Six Sigma team, also known as the Black Belt team, typically includes individuals from various departments and levels of the organization, who are trained and empowered to lead improvement projects. The Black Belt, typically an internal specialist, leads the team in gathering data, identifies the sources of variation, and proposes solutions to improve the process.
One of the key components of Six Sigma is the 5 Sigma framework, which is used to structure improvement projects. This framework involves the following steps:
Measure: In this phase, the team gathers data on the current process, identifies key performance indicators (KPIs), and develops a baseline for future comparison.
Analyze: In this phase, the team analyzes the data to identify the root causes of problems, and prioritizes the key issues that need to be addressed.
Improve: In this phase, the team selects and implements solutions to address the problems identified in the analyze phase. This step is often referred to as the solution phase.
Control: In this final phase, the team implements procedures to ensure that the new process are sustained over time, and the gains are not compromised.
In addition to DMAIC, the Six Sigma methodology also involves the 5 Whys method, which is used to drill down to the root cause of a problem by repeatedly asking the question "why" five times.
The Six Sigma metric, known as Sigma levels, is used to measure the performance of a process. The Sigma level represents the number of standard deviations from the mean performance that a process can achieve. Most companies aim for a minimum of Five Sigma level, which means that the process is capable of producing results that are beyond 3.4 defects per million opportunities.
A Six Sigma-certified individual typically undergoes a rigorous training process, which covers topics such as statistics, quality tools, leadership, and team building, project management, Design of Experiments, and Lever principles.
In conclusion, Six Sigma is a methodology that has been widely adopted by various industries to improve performance and quality. The methodology provides a structured approach to quality management and team-lead improvement projects, which makes it an ideal framework for continuous improvement.
