There are two different ways your product can be “bad.”
First, said product can be defective. This is to say something is wrong with it. It doesn’t work like it’s supposed to. It doesn’t look like it’s supposed to. The customer, who pays you good money, ain’t gonna be happy with said product.
It has multiple defects
Second, the aforementioned defective product might have multiple defects. This is to say there are many things ‘wrong’ with the product. It has 103 different scratches all over it, 14 surface mount components are not soldered correctly, and the text on the label is incorrect in 3 different places.
Manage the defects
In summary, it only takes one defect to create a defective product. But a single defective product can have a zillion defects.
What does this me to you, maker of said product? You need to stop focusing on how many defective units you produce… instead you should be laser focused on the number of defects you’ve created the past month.
Do you agree? Is this how you manage your business?
