The term “Six Sigma” may seem difficult to comprehend at times, but is actually very easy to explain. The term is derived from a character in the Greek alphabet, which is used for representing a standard variation in statistical mathematics. Statistically, Six Sigma can be defined as a near perfect method of production that restricts the number of defects to less than 3.4 for every million opportunities that exist for a defect to occur. This makes Six Sigma one of the preferred quality management techniques for achieving near perfect business processes through process improvement.
Data Driven And Disciplined Approach
Six Sigma follows a disciplined and data driven approach for eliminating defects in any type of business process, whether it is the product manufacturing process or after sale customer service. The two most commonly used methodologies in quality improvement projects are the DMAIC process (define, measure, analyze, improve, control) and the DMADV process (define, measure, analyze, design, verify). The former is used for improving the quality of business processes that have not met customer specifications and require improvement. The latter is used for developing new products or business processes that conform to 6-Sigma quality levels. Both the processes are carried out under the guidance of Green Belts and Black Belts, who in turn are guided by Six Sigma Master Black Belts.
Companies often want to know exactly how many benefits can be derived from Six Sigma training. Just to get an idea, one can look at the financial data of General Electric, one of the companies that have successfully implemented Six Sigma training. It is estimated that the total value of benefits derived from the training was close to a staggering $ 10 billion in the five years after implementation. It is estimated that on an average, Six Sigma Black Belts help companies save $ 230,000 per project. Given that most companies can execute 4 to 6 such projects per year, the total savings can translate into $ 920,000 to $ 1,380,000 per year.
Selection Process
After selecting the most appropriate type of training, a company needs to find the right consultant who has the necessary skills and experience in implementing Six Sigma programs. The selection of the training consultant will depend on the type of Six Sigma program that the company is planning to implement. Some programs are implemented all throughout an organization whereas others are implemented in a specific area only such as individual functional departments. The decision regarding the selection of the consultant needs to be made only after consulting other employees, as they are the ones who will eventually interact with the consultant during the implementation process.
After getting approval from the employees, it is advisable to seek references from business associates in other companies that have implemented such projects and can provide the necessary insights. Companies need to interview potential trainers and ask questions regarding their previous work relationships, referrals, total number of candidates trained by them till date, training materials used, earlier projects they have worked on, and their qualifications. This is essential since companies need trainers with a great deal of real-world experience. Companies need to inquire in depth about the type of training that the trainer is willing to provide. Usually, companies prefer training firms that operate online help desks for helping clients in dealing with problems that might arise after the training has been completed.

Six Sigma is a methodological strategy by which errors in a company’s current processes and plans are identified and strategies to rectify the same are formulated. It is fact-based technique, involving a lot of data handling, which provides scientific results for cost cutting and reduction in waste of resources. Today, many organizations, large and small scale, are applying Six Sigma to ensure improved, faster and cheaper services to their consumers without compromising on the quality quotient.
Various Levels
Implementation of Six Sigma requires professionals who have been trained in the program and have had exposure to practically applying the concepts in different organizations across industries to know how to go about its application on the job. There is a Six Sigma certification program that has to be undertaken for gaining knowledge about this particular quality measurement practice. Six Sigma certification is similar to other professional courses in that after having cleared specified guidelines and followed the required procedure, individuals are certified as capable of employing the gained knowledge in their respective field. There are several stages of the program and with each qualifying level, certain tests that have to be cleared. These levels are labeled in the same manner as a martial arts certification grade. There are various belts such as green belt, black belt and master black belt awarded to professionals who complete corresponding stages of the course.
Green Belt
The first level is completed when an individual finishes two weeks of training and passes the qualifying exam. This level is termed Green Belt, which teaches all the essential methodologies. The curriculum for the Green Belt involves DMAIC, which stands for five interrelated phases: Define, Measure, Analyze, Improve, and Control. It defines customers, their needs, recommended products and services, the assignment limits and plotting process flow to improve current methods. It measures performance by developing and collecting data from numerous sources and scrutinizing it for flaws by comparing it with surveys. The Analyzing phase bridges the rift between present methods and targeted results. Improving stage works out various solutions to redefine the earlier processes and deploys implementation plans. The Control stage teaches how to maintain the new changes that have been introduced and maintain the documentation and contemporary systems in accordance with the goals.
Black Belt
The Black Belt is awarded to a professional who completes four weeks of training, which involves Green Belt curriculum as well. This phase’s curriculum covers Green Belt subject matter as well. Black belt certified personnel usually train other Six Sigma aspirants and Green Belt holders, and in the process improve their abilities and skills as well. The Black Belt level enables individuals to master the Six Sigma roadmaps, extensive arithmetical methodologies and cross-functional process improvement. Black belts usually take up responsibility as Six Sigma team leads.
Master Black Belt
A person who has undertaken more than the required four weeks training and implements it in an organization as a Six Sigma program manager is awarded the Master Black Belt. These personnel are responsible for imparting knowledge to help Green Belt level and Black Belt level learners in improvising on their projects. They apply their skills in an organization by coaching other employees and helping them achieve the Green Belt and Black Belt certification without the company having to spend on training separately.

Six Sigma is usually associated with the complete overhaul of existing business processes, to reduce shortcomings and improve the quality of goods and services. Due to this belief, many companies with insufficient resources often avoid implementing the 6 Sigma concepts and methodologies in their business processes. These companies are often unaware that the Six Sigma concepts and methodologies can also be implemented with innovative shortcuts. These shortcuts are known to have the same affect on the quality as the standard 6 Sigma implementation processes.

Six Sigma training is beneficial to employees as well as the organization as a whole. However, since 6 Sigma training is expensive, many organizations stay away from it. Online training is the best answer to all these problems. It is cost effective and flexible.
