3Six Sigma Overview

Is 99% Good ?

4Six Sigma Overview

99% Accuracy

Practical Meaning of “99% Good”

• 20,000 lost articles of mail per hour

• Unsafe drinking water almost 15 minutes each day

• 5,000 incorrect surgical operations per week

• 2 short or long landings at most major airports each day

• 200,000 wrong drug prescriptions each year

99% Is NOT Good Enough Anymore

5Six Sigma Overview

6 – The Measurement

99.0% = 3.85

99.9996% = 6

Is there really a big difference between 99.0% & 99.9996%?

6Six Sigma Overview

Facts

• All work is a process

• All processes have variation and waste

• Variation causes defects waste causes loss

• Processes can be improved by understanding the nature of the variation and waste

15Six Sigma Overview

The MacFeenie Company was founded by Fannie MacFeenie of Fredericksburg, Florida. The MacFeenie Company finds first the finest freshest fish for feeding hungry people. The MacFeenie Company can compete with Florida’s finest fish foundries because Fannie MacFeeneie who is the founder of the company deployed Six Sigma five years ago. Now The MacFeenie Company finds defects caused by variation and removes them from processes. This helps the MacFeenie Company satisfy their customers first, thereby facilitating valuable market share from fierce fish foundry competition.
