What is Six Sigma:

  • Lean Six Sigma is a method that relies on a collaborative team effort to improve performance by systematically removing waste and reducing variation. It combines lean manufacturing/lean enterprise and Six Sigma to eliminate the eight kinds of waste (Muda): Defects, Over-Production, Waiting, Non-Utilized Talent, Transportation, Inventory, Motion, and Extra-Processing.
  • Lean Six Sigma not only reduces process defects and waste, but also provides a framework for overall organizational culture change. By introducing Lean Six Sigma, the mindset of employees and managers change to one that focuses on growth and continuous improvement through process optimization. This change in culture and the mindset of an organization maximizes efficiency and increases profitability.
  • In order to successfully implement Lean Six Sigma, a combination of tools from both lean manufacturing and Six Sigma must be used. Some of these tools include kaizen, value-stream mapping, line balancing, and visual management.


Six Sigma Approach:

There are two major methodologies used within Six Sigma, both of which are composed of five sections,

DMAIC: The DMAIC method is used primarily for improving existing business processes. The letters stand for:

  • Define the problem and the project goals
  • Measure in detail the various aspects of the current process
  • Analyse data to, among other things, find the root defects in a process
  • Improve the process
  • Control how the process is done in the future

DMADV: The DMADV method is typically used to create new processes and new products or services. The letters stand for:

  • Define the project goals
  • Measure critical components of the process and the product capabilities
  • Analyse the data and develop various designs for the process, eventually picking the best one
  • Design and test details of the process
  • Verify the design by running simulations and a pilot program, and then handing over the process to the client

How Six Sigma helps:

Objectives of Six Sigma:

The goal of Six Sigma is to increase profits by eliminating variability, defects and waste that undermine customer loyalty. Six Sigma can be understood/perceived at three levels: Metric: 3.4 Defects Per Million Opportunities.
