Six Sigma is a business management strategy originally developed by Motorola, USA in 1986. As of 2010, it is widely used in many sectors of industry, although its use is not without controversy.
Six Sigma seeks to improve the quality of process outputs by identifying and removing the causes of defects (errors) and minimizing variability in manufacturing and business processes. It uses a set of quality management methods, including statistical methods, and creates a special infrastructure of people within the organization ("Black Belts", "Green Belts", etc.) who are experts in these methods.
Each Six Sigma project carried out within an organization follows a defined sequence of steps and has quantified financial targets (cost reduction or profit increase).
The term Six Sigma originated from terminology associated with manufacturing, specifically terms associated with statistical modeling of manufacturing processes. The maturity of a manufacturing process can be described by a sigma rating indicating its yield, or the percentage of defect-free products it creates.
A six sigma process is one in which 99.99966% of the products manufactured are statistically expected to be free of defects (3.4 defects per million). Motorola set a goal of "six sigma" for all of its manufacturing operations, and this goal became a byword for the management and engineering practices used to achieve it.

Six Sigma is generally used for defect reduction projects, and it can also help reduce the variation within a process. Six Sigma offers a variety of tools, and a Black Belt is capable of selecting the most suitable tool for their specific problem. Black Belts are typically the individuals who drive the project forward, while Green Belts are often responsible for data collection. The different grades in Six Sigma include:
1. Green Belt
2. Black Belt
3. Master Black Belt
4. Champion

Six Sigma is a powerful methodology that can be applied to improve business processes. It is a structured approach to reduce variations in any process, whether it is in manufacturing, sales, marketing, IT, BPO, accounting, or purchasing. Variation in any process happens to be the root cause which eventually leads to defects and customer dissatisfaction. Implementation of Six Sigma helps to remove these variations from the process, thereby improving costs, quality, and eventual customer satisfaction.
There are two primary methodologies in Six Sigma: DMAIC and DFSS. While DMAIC is used for making improvements in existing processes, DFSS is used for new products and services or when the improvements that can be made with DMAIC are not sufficient.
DMAIC can be considered to be reactive in nature, in the sense that a process already exists and is producing defects. The DMAIC approach is used to identify the root cause of the problems and then fix it. The acronym DMAIC stands for Define-Measure-Analyze-Improve-Control. This is a phase-by-phase approach to solving a problem. The DEFINE phase talks about the first step, which is the identification of the problem statement, goals, and benefits. As Six Sigma is a data-driven approach, the MEASURE phase ensures the collection of accurate data. If the data is inaccurate, incorrect decisions may be made. The ANALYZE phase involves making hypotheses and using data to prove or disprove them, establishing the real root causes of the problem. The IMPROVE phase focuses on finding the best possible solution to solve the root cause of the problem, optimizing the solution and addressing potential failure modes before deployment. The final phase, Control, ensures the solution is sustainable in the long run, quantifying any financial benefits obtained and transitioning the improved process to the process owner.
Some salient features of the Six Sigma methodology include:
• Six Sigma is a data-driven approach - providing guidance on data collection and analysis.
• Six Sigma is process-focused - emphasizing studying underlying processes for lasting improvements.
• Six Sigma offers a structured roadmap - utilizing defined stages for problem resolution.
• Six Sigma employs non-common-sense approaches - introducing innovative solutions for improvement.
• Six Sigma integrates management methodologies - combining proven techniques into a flexible methodology.
• Six Sigma validates projects through financial benefits or KPI impact.
• Six Sigma requires improvement projects led by trained experts (Green Belts and Black Belts) for effective results on a project basis.
By following the principles of Six Sigma, organizations can efficiently enhance their processes and achieve sustainable improvements in quality and customer satisfaction.

In layman's language, Six Sigma is the big brother of Kaizen. When a cricket player is striking for singles or twos to protect his wicket, he is doing Kaizen. When he is hitting fours or sixes to win the match, he is doing Six Sigma.

Six Sigma explains the main concept of minimizing defects. Simply put, it states that for every million production operations, only three defects are allowed. This means improving the quality of products, services, and operations, aiming for the highest customer satisfaction at an economical cost. It focuses on achieving high-quality products at low costs through statistical analysis of data at a micro level. It is a very interesting subject that one should learn and practice.
