    I am certified BB in manufacturing company with manufacturing degree and experience. I would like to get into healthcare (hospitals etc) as a BB but not sure of the difficulty level, if any. Company I work for is extensively into SS andI had to complete 2 projects with certain financial savings and proof. So this is an excellent program and training at the corporate company, not an internet course etc. Please let me know if you think it is a bad transfer from manufactruring into healthcare with only manufacturing (molding) background? Thanks for your time.

    Are you talking about sample size? For example to determine the sample size to detect a specific dimension with a certain % confidence? You need

    Arn’t you clever…oh yes you are…now reread your post and update with some additional builds to support your argument.

    I’m curious, MBB Dude, what % of time do you expect your “A” players to spend drumming up projects out of reluctant process owners, or do you always have a full hopper? Where I work, it is expected that the BB will get their own projects by being a pain in the neck to managers until they agree to charter a project. Do you think BB’s are supposed to do much of that, or used purely to analyze and execute projects?
    Thanks

    I have found the discussion a bit entertaining but not very enlightening.  As a former student of Darth, I can say that in the over 12 years I have worked in the process improvement field I have never had a better instructor.  I think it is great to have different sources of materials however when it comes to testing and certification, I believe personal, direct contact between the assessor and the one being certified is necessary to ensure validity of the knowledge.  If IQF is not ensuring proper testing procedures, then this discussion has pointed out a gap for continual improvement.
    As for finding Darth, it is nice to know he is still out there teaching and as a former student, I miss the tutelage.

    A better question to ask is not who has started to implement Six Sigma but who are Six Sigma organizations – can I count them on my hands?  Coming from automotive, I can say a lot of the companies listed (including Ford and Visteon) are a very long way from that achievement.  That’s the list I want to see.

    Buried in the previous replies (and your own admission) is the brutal reality of the problem.  You have implemented and are guiding I process for which you are not appropriately trained and experienced.  Please don’t take this as a harsh criticism but an opportunity for reflection.  A SS effort without a TEAM of highly competent, complementary group of  MBBs to teach and guide the BB and SS organization is destined to follow a hard road.  You should make it a priority to put the infrastructure in place to develop the BB team.  BB training is like most university courses – a good start but you need the experience to really apply it well.  That’s where the MBB earn their money. Good luck.

    The use of parametric control charts (p,np,c,u) require that certain distributional assumptions be met.  It is often more accurate (and better for the detection of process changes) to convert discrete data into defect rates which is suitable for ImR and XmR charts.
    Regarding sample size – Gabriel is correct in that it depends on the existing defect rate and what you are trying to accomplish with sampling.  If the presence of a defect occurring in a batch influences the likelihood of other defects/defectives being present that also influences the sample size.
    Finally, the only way to catch a onesy or twosy is 100% inspection.  Likewise, even a highly capable (eg.six sigma process) does not gaurentee that defects/defectives will not get to your customer.  If you must send 100% defect/defective free product – you have to sort 100%.
