Six Sigma stands for Six Standard Deviations (Sigma is the Greek letter used to represent standard deviation in statistics) from mean. It provides the techniques and tools to improve the capability and reduce the defects in any process by constantly reviewing and re-tuning. It allows for only ...
To implement Six Sigma within an organization, the first step is to properly make the case for statistical tools like Six Sigma and its potential benefits to getstakeholderbuy-in. Additionally, it's important to set the expectation that being entirely defect-free is not realistic. However, there...
