    Can anyone tell me if there is a difference between Kaizen and Six Sigma?  I know Kaizen is a Japanese efficiency production tool.  Are they basically the same thing?


    Lean (basically) is the pursuit of waste elimination while Six Sigma pursues perfection in a process .
    Lean focuses on eliminating waste (Non value added steps)
    Six Sigma focuses on improving quality (Value Added seps)


    I would offer, YES and NO.
    Difference, YES.  Typically I have seen kaizen events last about 5-7 weeks (a few weeks of prep leading up to a one-week event followed by a one or two week follow-up period).  Where Six Sigma projects can last 3-4 months, maybe even 6-8 if it is really complex.
    Difference, NO.  You can easily use the DMAIC process to execute a kaizen event if you like.  We have done that a number of times and it worked well.
    Either way you are using a closed-loop process (DMAIC or PDCA) to evolve a process and improve the “way of doing business”, regardless if you are working to minimize variation or eleminate waste.
    Good luck…
