Six Sigma is a set of quality management methods, techniques and tools for improving the quality of products and processes by identifying and removing the causes of defects and minimising variability. Originally developed by Motorola in the 1980s, it has since been adopted by many other companies around the world.
Six Sigma is based on the (DMAIC) five steps:
- Define the problem or opportunity that you want to improve
- Measure the current state of the process and identify the root causes of defects
- Analyse the data to identify the root causes of defects
- Improve by eliminating changes to the process to eliminate the root causes of defects
- Control to ensure that the improvements are sustained over time
