For a "black belt" to even ask this question points to the fallacy behind Six Sigma. Had the "black belt" truly studied under a sensei and not just taken an on line course and passed a test he/she would know to look for variation. True students of quality know that variation is the enemy. A true student of quality tells his boss what the projects should be, not the other way around.

It's quite obvious that there are a great deal of "black belts" who are still grasshoppers who have yet to snatch the pebble from Master Po's hand.
