What do you understand about Six Sigma?
Six Sigma is technically a data driven approach that helps in processing of the improvement that seeks to minimize defects and variations in processes. It was developed in the 1980s by Motorola and then went on to spread to other firms, including General Electric.
Some important Features are:
- Quality improvement
- Use of data and statistics
- Aims at 3.4 defects per million opportunities
- Follows DMAIC
Objective of Six Sigma
The main objective of Six Sigma is the identification and elimination of defects in a specific process.
Example
If you take an example of a manufacturing company, then through the application of Six Sigma the defects in the process of production and the errors in the assembly lines are thus reduced.
What Is Lean Six Sigma?
Now letās learn what Lean Six Sigma is. It is basically a hybrid methodology that technically incorporates the principles of Lean manufacturing and Six Sigma. The primary aim of Lean Six Sigma is the elimination of the waste and increase of the speed.
Here are some important features:
- Combines efficiency + quality
- Eliminates waste that is the non value added activities.
- Improves process speed and flow
- Uses tools like:
Value Stream Mapping
Kaizen
5S methodology
Objective of Lean Six Sigma
The aim is to provide maximum value to customers in terms of minimum waste and maximum quality.
Example
In a service this methodology actually helps in the reduction of the waiting time while ensuring the accuracy of the service delivery.
