# Doing Business In A World Of Growing Risk

__Six Sigma__ CTIC: NOV COURSE SCHEDULE

### Six Sigma refers to **decreasing the number of defects to 3.4 defects** (P**ercent Defective = 0.00034%**) **per million opportunities** (**99.9997% success rate**). Six Sigma tackles variations in processes, minimizes defects and waste, thus improving the bottom-line.

Some Examples:

- One (1) Short or long landing at major airports every five years.
- One (1) hour without electricity every 34 years.
- One (1) warranty claim for every 980 new automobiles.
- One (1) unsafe minute of drinking water every seven (7) months.

There is one fundamental equation which underlines Six Sigma:

**Y = f(x) + E**

** **

### Y

= the desired results (the outcome)

X = the inputs

*f* = the function (process by which inputs are transformed to outputs)

E =presence of error/variation (this is actually the Greek letter Epsilon)

- Thus, a particular set of inputs (X) are transformed, into an output (Y), by some function (
*f*) or process. - Outcomes are the result of some function or process acting upon the inputs.
