How Do I Know If I Have Good Data?

Six Sigma beginners get hung up on the question: “Do I have good data?” You never will. Here’s why and what to do about it.

“People are always asking me, “Jay, how do I know if I have good data?” I’m going to tell you what: you don’t. All data is either collected poorly or whatever, and if nobody’s been using it, they collect it even more poorly.

Most data is systematically distorted to make somebody look good. Your task, should you choose to accept it, is to recognize that it’s not going to be the world’s best data, and waiting for the world’s best data will not solve those problems that are waiting for you.
