    I’m interested in learning about six sigma and it’s application but need more understanding of the process, like what is the difference between four sigma verses six sigma

    Don’t get caught up in the 6 sigma metric. Motorola coined the term as goal for an acceptable defect level for competiveness in their markets. Defining the sigma level can depend how you identify defect units and opportunities. Bottom line, use the methodology to reduce defect levels in whatever product, process or transaction that require improvement. Set your goals as %reduction in defect levels. Just make sure the measurement technique remains constant. There’s too many arguements over a “natural 1.5 sigma shift” in a process to be splitting hairs over 4 or 6 sigma. After all, I believe Motorola admits they are only now a true 6 sigma levels for just a few of there processes.
