The Statistical Thinking Underlying Six Sigma Is Based on the Following

The statistical thinking underlying Six Sigma is based on the following three principles:

A) all activities can be controlled,employee empowerment is the best control tool,and 100 percent control is possible.
B) all work is a process,all processes have variability,and all processes create data that explain variability.
C) all work activities can be done accurately most of the time,empowered employees are necessary for effective control,and good statistical data are an empowered employee's best control tool.
D) all work is a statistically controllable process,100 percent control is possible,and every well-controlled process is defect-free.
E) most business processes are subject to control,Six Sigma can remove variability in how processes are performed,and most defects can be eliminated.
