7.8. SUMMARY
This sampling of Six Sigma projects represents a tiny fraction of all the improvements and changes to processes going on throughout the world. Some people ask, "Wouldn't these problems have been solved anyway?" And the answer is, "Some might have."
But in many cases, it's likely that the approach taken would not have led to the powerful solutions we see here, where customer needs, process knowledge, and data drive the effort. And it's certain that without the energy Six Sigma is prompting companies to apply to identifying their key problems (not to mention fixing them), many of the projects being tackled by Six Sigma teams would not have been addressed at all.
