"But I reckon I got to light out for the Territory ahead of the rest." -- Mark Twain, Adventures of Huckleberry Finn
...we borrowed an idea from Sakichi Toyoda, the founder of Toyota. He calls it Five Whys. When something goes wrong, you ask why, again and again, until you ferret out the root cause. Then you fix the root cause, not the symptoms.This is fantastic advice for any business. How often do we only work on solving the symptoms of a real problem? How often do we only ask why once when we are trying to figure out customer behavior?
