Six Sigma Information

Six Sigma information can be easily obtained from our site. It is a process improvement method, which provides an efficiency rate of 99.9997% to the process and limits the number of chances of defects to less than 3.4 defects per million opportunities. It aims at improving the quality level of the product as well as the market value of the organization. It is totally a customer oriented quality control program.

It’s very important to know about the origin and history of the term ‘Six Sigma’. Sigma is the 18th letter of the Greek alphabet and is used for denoting the deviations of statistics in mean. “Six Sigma” denotes the Six standard deviations from mean. Bill Smith originally formulated Six Sigma, in 1986. Six Sigma is the registered trademark of Motorola Inc. [Source: Motorola website]

The following table helps in defining the degree of Sigma level along with its DFMO (Defect per million opportunities):

Sigma level DFMO
One Sigma 690,000.000
Two Sigma 380,000.000
Three Sigma 66,800.000
Four Sigma 6210.000
Five Sigma 230.000
Six Sigma 3.400

Origin of the Six Sigma Concept: The main factors that led to the discovery of the Six Sigma methodology are:

  • The corporate waste faced by the organizations kept on increasing because of which the profit margin of the companies decreased. This increased the over all cost of the product. As a matter of fact, the final product launched in the market was of higher price. It became problematic for the company to satisfy their consumers. To preclude such a predicament and achieve the primary aim of achieving the consumer satisfaction, it became important to reduce the presence of corporate wastes within the process. Six Sigma emerged as a vital solution for dealing with such a case.
  • Many old firms who were claiming their success using old process like TQM could not carry their success graph for long due to the growing competition in the corporate sector. Organizations needed a methodology, which could help them to achieve the desired objectives and goal.
  • Companies demanded a methodology, which could serve the primary aim of achieving consumer satisfaction without compromising with the quality level of the product. Any improvement in the quality level of the product meant a satisfactory improvement in the overall reputation of the company. Six Sigma, being a customer oriented program helped in achieving such goals.
  • On-time delivery of the product became a problem for many companies. In addition, the increase in the cost of the final product due to unnecessary production waste became a matter of discussion. Six Sigma process improvement methodology helped these companies in lowering the manufacturing cost of their products and also helped them to reduce the production time. This ensured an on-time delivery of the product to the market.
  • Organizations were in need of an effective process, which would improve their value in the market.
  • The working staff of the companies demanded a favorable ambience for handling the problems associated with the processes. The working pressure and unwanted predicaments made them tensed. As a result of which the employees demanded a better job satisfaction.

How to do the Six Sigma Course: The minimum qualification for enrolling to a Six Sigma course is a graduation degree. Usually, an individual with better inherent ability in subjects such as mathematics and physics is preferred. The Six Sigma certification course can be acquire through many available options. On-premises Six Sigma certification available at various institutes around the country is one of the most popular option available for acquiring the Six Sigma training course. A candidate has to visit these institutes to acquire the concerned training. Six Sigma course can also be acquired through a Six Sigma trainer. A Six Sigma trainer may be appointed and the schedules may be decided according to one’s own convenience. It can also be acquired through the online training programs, offered by various authentic websites on the internet.

Fundamentals of Six Sigma:

  • The Six Sigma quality control methodology is more customer oriented whereby the needs and the requirements of the consumers are kept in mind.
  • Its process improvement statistics relies more on data and figures rather than relying merely on assumptions.
  • It focuses on minimizing the errors and maximizing the output
  • It aims at identifying the factors, which create deviation in the desired output and thereby aims at finding the solution to the existing problems by relying on facts and data.
  • Constant focus on the improvement of the process is given.
  • Betterment of the quality of the product is given the primary importance as it helps in achieving the customer satisfaction.
  • It constantly aims at measuring the potential of any process by marking its progress.
  • The number of possibility of defects per million opportunities is brought down.
  • Six Sigma methodology calls for the betterment of in-house communication within any organization.
  • It defines the importance of setting up of goals and objectives for any process.

Six Sigma Methodology: Six Sigma works on two methodologies, namely DMAIC, which stands for Define, Measure, Analyze, Implement and Verify and DMADV, also known as DFSS (Design for Six Sigma). DMAIC helps in improving the process and thereby helps in improving the quality of the product by reducing the number of possibility of defects to less than 3.4 defects per million opportunities. DFSS, on the other hand, helps to design for new products and the processes, which would carry out the execution of the same.

Six Sigma aims at maintaining the quality of the product and constantly aims at improving it. It is more consumer oriented, because of which the needs and the demands of the consumers are kept in mind while designing any Six Sigma process. This helps in achieving the consumer satisfaction, which thereby helps in achieving a good market status for the company.

Benefits of Six Sigma:

  • It teaches how to measure the causes of variations.
  • It helps in decreasing the number of defects.
  • It helps in increasing the quality level of the product.
  • It helps in achieving the consumer satisfaction by providing them a quality product.
  • It provides a job satisfaction ambience for the employees.
  • It reduces the cost price of the product by reducing the production cost of the product.
  • It solves the existing problems in any firm.
  • It helps in providing on time delivery.
  • It reduces delivery problems with the suppliers.
  • It improves the market value of the company.
