Six Sigma Part 5: Different Techniques to implement Six Sigma

Six Sigma uses various statistical and data-based techniques to improve the existing process and develop a new approach to eliminate waste from the manufacturing process. 

Following are the essential techniques used in industries to implement the concept of Six Sigma:

 

[1] Brainstorming: It is one of the essential techniques usually applied in the “improving” phase of the DMAIC Methodology. Brainstorming involves thinking and developing creative ideas to approach a particular problem. A typically green belt or black belt person heads the brainstorming session in the industry.

 

[2] Root cause analysis: It is also called the why technique, which is used to find the root cause of the problem in a particular manufacturing process. It is used in the “analyze” phase in the DMAIC cycle. 

 

[3] V.O.C.: It stands for “Voice of customer” and is one of the essential techniques for six sigma implementations. The feedback of the customer is taken either through external or internal means. 

 

[4] 5S System: The system aims to remove waste and eliminate bottlenecks from the inefficient systems, resources, or the workplace. The five steps used are Seiri (Sort), Seiton (Set in Order), Seiso (Shine), Seiketsu (Standardize), and Shitsuke (Sustain).

 

[5] Kaizen (Continuous improvement): It is a powerful technique that powers a continuous engine for business improvement. A constant process of quality checking of the process helps eliminate a lot of waste.

 

[6] Benchmarking: It is a technique that employs a set of standard measurements. It involves comparing with other businesses to gain an independent appraisal of the given situation.

 

[7] Poka-yoke (Mistake proofing): This technique comes from the Japanese word meaning “to avoid errors.” In Poka-yoke, employees spot and remove inefficiencies and human error during the manufacturing process. 

 

[8] Value stream mapping: It charts the current flow of materials and information to design a future project.
