    We have researched the problem solving tools to figure out which one would work best (PDCA, DMAIC, 8D, etc.).  Toyota uses PDCA.  The best approach, I’ve read, is the one your company standardizes all problem solving on.  I believe a company should standardize on one problem solving methodology so everyone is using the same approach.  A common methodology will let everyone know what questions to ask, what approach to take, and what to expect during the process.

    If my process were not normal, then the Cpk would have little,  if any validity at all.  After reviewing the calculations for Cpk, I would predict the PPM out of spec would be the same for either process.  The improvement method would be much easier for the shifted process, as long as the adjustment to center was simple.  Reducing the spread of the “centered” process would probably take a little more work.  Thanks for all the input.

    If both processes had the same tolerance, then the shifted process would have to have a smaller std dev in order to achieve the same Cpk.  Forgot any mention of the previous “5 letter word”.  Statistically, the defects may be smaller for the shifted process, but practically speaking, is the difference even worth the mention?

    What is correct, they produce the same number of defects or the off center process would produce less?  Please explain a bit more for the theory side.  Are you considering just this point in time, any 1.5 sigma shift over time, etc.?

    Hi all. We have a National laboratory accreditation system in Australia overseen by NATA (National Association of Testing Authorities).  I noted in another discussion thread on ISO and SS that in the US some work is occuring to bring together indistry standards, ISO, and Lean SS in an over arching framework for clincal laboratories. Am I correct in the assumption that the expectation is Lean SS will be mandated by ISO as the improvement methodology for pre and post anylytical phases for clinical labs?

    AJ … I attended a 1 week GB program at a customer’s site.  30 hours between long breaks and 1/2 day Friday.  The 20+/- 3 modules were taught by about 15 different instructors … ugh.
    My company’s GB program is 2 weeks for operational or transactional, then there’s 3 weeks for LDFSS GB classes.  Also instructors are 2-3 per week and of a higher caliber that what I witnessed with our customer’s program.
    Providing the practical tools needed for project work is key … DMAIC … and having graduates then apply the tools with mentoring belts is as important.  Learning the lingo and tools available will have terrific returns.
    Good Luck!

    Wolfgang,
    I’ve done a few inventory projects, none as a Kaizen event, but the opportunity is certainly there to hold one.  Key for you will be a cross-functional team … consider a major supplier, if available a person from a sister division that has either a similar issue or has made some headway, and of course the customer (folks pulling from your storage area) … these folks coupled with representatives from your storage area would be a great start.
    No one likes to go into a Kaizen with pre-conceived solutions, but things like point of use storage, self-check outs, employment of bar coding, etc. all seem to be plausible solutions.
    Have fun!
