Six Sigma Green Belt: What is Sigma?

Sigma (σ) is an eighteenth letter in the Greek alphabet used by statisticians to measure the variability or variation in any process. A company’s performance is measured by the sigma level of their business processes. Six Sigma is a statistical definition of how far a process deviates from perfection.

What is the Background of Six Sigma?

Six Sigma’s magic is not in statistical or high-tech razzle-dazzle. Six Sigma relies on tried and true methods that have been around for decades. In fact, Six Sigma discards a great deal of the complexity that characterized Total Quality Management (TQM). There was over 400 Total Quality Management (TQM) tools and techniques. Six Sigma takes a handful of proven methods and trains a small cadre of in-house technical leaders, known as Six Sigma Master Black Belt, Six Sigma Black Belt, Six Sigma Green Belt and Six Sigma Yellow Belt.

It would be a mistake to think that Six Sigma is about quality in the traditional sense. Quality, defined traditionally as conformance to internal requirements, has little to do with Six Sigma.

How Does Six Sigma Define ‘Quality’?

For Six Sigma purposes, quality can be defined as “the value added by a productive endeavor”. Quality here comes in two flavors: Potential Quality and Actual Quality. Potential Quality is the known maximum possible value added per unit of input. The actual quality is the current value added per unit of input. The difference between potential and actual quality is ‘waste’. Six Sigma focuses on improving quality (i.e., reducing waste) by helping organizations produce products and services better, faster and cheaper

The essence of Six Sigma methodology is to solve problems that are impacting business performance. It has saved a huge amount of money and improved the customer experience for a large number of organizations across the world, yet it is applied in an inconsistent and often reductive fashion in many companies. This has led to criticism in the literature and a number of abandoned implementations.

Although many proponents of Six Sigma stress the uniqueness of the approach, it is, in fact, part of a continuing evolution of thinking in what might broadly be called “Quality”. It is important to see Six Sigma within this wider context.

Six Sigma’s Problem Solving Framework

Six Sigma’s most common and well-known methodology is its problem-solving D-M-A-I-C framework. D-M-A-I-C is an acronym that stands for Define, Measure, Analyze, Improve and Control. In other words, D-M-A-I-C is the classic Six Sigma problem-solving process. The roadmap to D-M-A-I-C starts with defining an improvement project. Therefore; the first phase that we are going to look at in DMAIC framework is ‘DEFINE’ phase.

Traditionally, the D-M-A-I-C approach is to be applied to a problem with an existing, steady-state process or product and/or service offering. In Six Sigma methodology, variation is the enemy. It means variation from customer specifications in either a product or process is the primary problem.

DMAIC builds on three fundamental principles:

  1. Results-focused; driven by data, facts, and metrics
  2. Work is project-based (short-term in nature, with length depending on scope and complexity) and project-structured, versus an ongoing process
  3. Inherent combination of tools-tasks-deliverables linkage that varies by step in the method

Variation can take on many forms. DMAIC resolves issues of defects or failures, deviation from a target, excess cost or time, and deterioration. Six Sigma reduces variation within and across the value-adding steps in a process. DMAIC identifies key requirements, deliverables, tasks, and standard tools for a project team to utilize when tackling a problem.
