Six Sigma is a way to minimize process variations that occur and reduce product defects or services out of specification by using statistical methods and other quality tools as incentives. In solving a problem, there is a method called DMAIC six sigma which will be explained as follows :
1 Define to validate problems
2 Measure to measure the problem
3 Analyze to find the source or root of the problem
4 Improve to define, prioritize, and implement the solution of each problem that has been validated
5. Control to keep the solutions that have been applied to keep it running, so that the problem does not arise again.
In addition, six sigma as well as practical management systems that focus on four areas, namely:
