It’s one thing to see the numbers and it’s a whole other thing to see how it would apply to your daily life.

|Situation/Example||In 1 Sigma World||In 3 Sigma World||In 6 Sigma World|
|Pieces of your mail lost per year [1,600 opportunities per year]||1,106||107||Less than 1|
|Number of empty coffee pots at work (who didn’t fill the coffee pot again?) [680 opportunities per year]||470||45||Less than 1|
|Number of telephone disconnections [7,000 talk minutes]||4,839||467||0.02|
