Wondering About Six Sigma Programs

I’ve been told the best way for a company to gets its act together is with six sigma programs. I wonder if we shouldn’t check out 6 sigma online as a way of streamlining our operation.
From what I’ve seen, Six Sigma Methodology looks like it might be just what the doctor ordered for us. We’ve been stagnating for too long.
I know that six sigma programs was instrumental in the turnaround of a friend’s business. Hopefully it can do the same for us.
