What is Six Sigma?

Six Sigma is a quality management approach to minimize or eliminate defects in products or services. It was originally developed by Bill Smith in the year 1986 to improve manufacturing processes. It is later widely adopted by many organizations for quality improvement. It is based on statistical analysis to detect unknown problems.

The word 'Sigma' in Six Sigma means data analysis. Six Sigma methodology typically includes stages like 

  • Define - Gather requirements from the customer and define the process.
  • Measure - Calculate the performance of the product.
  • Analyze - Analyze the product for defects or errors.
  • Improve - Come up with the improvement actions.
  • Control - Maintain the process improvement.

We have to gather all the details of a product or service and calculate the standard deviation (sigma) between the mean and the nearest customer specification limit. We should limit the defects of the product to 3.4 per million opportunities. 

Organizations that adopt Six Sigma identify customers’ needs and expectations and plan for Critical-To-Quality (CTQ) characteristics. These characteristics are then implemented in the design of the product. 

Advantages of Six Sigma

Here are some advantages of using Six Sigma in organizations.

  • It makes sure that standardization is followed for all the business development of products.
  • It improves customer service by delivering a product that exactly meets the customer needs.
  • It provides better compliance.
  • It provides shorter cycle times to launch the product to market.
  • It cut down costs for product development which leads to revenue growth.
  • It enforces continuous improvement in identifying and eliminating defects that prevent the product from performing to its optimum level. 
  • It removes the inefficient steps that drain effort and resources.
  • We can build high-quality products.
  • It improves the efficiency of all characteristics of operations in the product.

Six Sigma Certification

Six Sigma certification is a way of proving that the person who took the certification is skilled in detecting defects or errors in a product and removing them. It helps organizations to validate a professional. To get Six Sigma certified, an individual should have a certain level of experience in Six Sigma.

The Six Sigma green belt individuals will be able to perform statistical analysis like creating charts, process maps, etc. They usually get a lead role in a project and assist black belt individuals in data analysis. They also learn problem-solving frameworks like DMAIC. They work in improving products and processes.

Black Belt 

This is an advanced certification level. The black belt professionals master the Six Sigma skills. They will be able to lead and plan more complex projects. They will also be able to drive changes to products, analyze statistics, and deploy LSS (Lean Six Sigma) principles. They supervise a team of green belts for a project.
