I know this may seem somewhat self-evident, but have you considered doing a simple literature review to answer your own question? So much is out there on the Internet – the available information is like water drops in a world-wide rainstorm. At this point in the life cycle of Six Sigma, a great many people have applied the tools and concepts. In fact, a large portion of these individuals has taken the time to document their work and share it with the rest of us. All you have to do is plug in a few key words – then watch the world unfold before your very eyes. What I can tell you is a mere drop in the bucket next to what a on-line literature search can reveal to you.
Can you explain how Six Sigma can apply to reducing invoicing errors and improving payment to suppliers?
