    Hi , I´m from Brazil . Sorry if I commit  some gramatical mistakes.I have some familiarity with the Lean Manufacturing and Kaizen Methodology. I would like to know if it´s possible to ally Kaizen and Six Sigma , and how can I do this?Thanks , Kazama

    Kaizen can not be done without using the tools shared by Lean and SS.  And, SS makes no sense if you statistically find the opportunity to improve and take no additional steps to do so.

    The lean and Kaizen techniques focus on velocity through the process by removing waste (muda).  Six Sigma’s key focus is the reduction of variation.  I would suggest that formulating a lean strategy for your business focussing on the “customer needs” is a good thing.  You will find that you will be able to lean out your processes only so far until the variation stops your progress.  For example iIf you remember back to the calculation of Kanban sizes it takes into account the standard deviation calculation, or variation, within the process to set the levels.  Although you may impact the variation by say 20% using lean tools the classic Six Sigma tools will enable you to adress the true root causes and poka-yoke them.
    Hope this is of help.

    While I do not share the same degree of SS as Adam, I do not also share the same definition of Kaizen.  Yes, Kaizen is geared toward speed, the central focus is on standardization through the Kaizen event.  EX:  While investigating a soldering problem, (hand soldering of wire to a terminal by placing the insulator into a hand held holder), we were experiencing variances in the solder weld that caused contact to become loose (expansion of plastic by the metal contact which expanded then contracted as it cooled) as well as cold soldering as an attempt to not burn/over heat the contact.  Our final solution was to put an aluminum shim in the bottom of the holder.  The result eliminated heating time by 1.5 sec/piece, excellent flow of solder, and reduce heat transfer from the contact to the insulator eliminating looseness.
    We increased the process time, eliminated the overheat problem, and reduced the variation of heat transfer from the contact to the plastic insulator.
    And for what ever its worth, in regards to Kanban, we evolved to Heijunka which reduced our end-of-line stock from 2 hours to 20min, and thus reduced our inventory stock from 2.5 days to 6 hours.  (Except for Ford products which has a variation of 5 to 10 days where as Toyota has a variation of 2 to 4 hours).
    If you would like more examples, I shorted the length of my shot gun allowing me to acquire 4 to 6 possums per shot with less pellets per steak.
