The main objective was to improve the quality of the process by minimizing the defects or errors to an extent that they are statistically insignificant.

The term Six Sigma is a resultant from the bell curve that is used in statistics where one Sigma denotes one standard deviation away from the mean. The defect rate is said to be immensely small when the progression displays Six Sigma’s, where three are above the mean and three below.

In simple terms, Six Sigma is a management technique that is designed and implemented to enhance the efficiency of the business processes by knocking out the possibilities of potential errors. Therefore, Six Sigma is a framework of quality management tools and techniques conceived to improve businesses by removing probable inaccuracies.

  • Seiri (Sort),
    •  Seiton (Set In Order),
    • Seiso (Shine),
    • Seiketsu (Standardize), and
    • Shitsuke (Sustain)

7. Value Stream Mapping- This technique is used to define and evaluate the movement/ current flow of raw materials and information from the beginning of the process or the operational activity till the time the product or service delivered to the end-user/customer.

This technique is designed so that the defects are almost impossible to occur in operations or business activity. Poka-Yoke is a well-known process analysis tool.

9. Gemba walks- In Japanese Gemba means “the actual place”. This concept gives a great opportunity for the staff members to step aside from their everyday responsibilities and take a walk on their floor space to identify the inefficient activities and scope for continuous improvements at the workplace. The goal is to deep dive into the issues and problems and seeks the best possible solutions rather than making shallow comments.

10. Pareto Chart- This is a six sigma technique that depicts the relationship and differences between various groups of data in the graphical representation form. The Pareto chart is a bar graph representation that indicates the occurrence and the number of defects along with their collective impact on the business process. This proves to be useful in prioritizing and rectifying the errors and defects to seek overall improvement in the activities.
