Brit
Agree  fully  with  your  point  of  view.
Please submit  brief  outline ,indicating  how  to  encompass  the  3  methodologies SS-Lean & TOC,just  one  page.thanks  and  regards.

some  350??

Please  explain the  difference between the ASQ -BB Certification  Exam. and  the  Villanova’s Certification Exam.??thanks

NO?
Those  are  the  SS-Tools?
Lean  Tools  are  different,just  like 5Ss,TPM,Poka Yoke,Kaizen  Blitz,VSM,FMEA….etc

Does  that  mean that SS is no-more valid or  is  it  an indication of “lack  of  efficiency” ??

Having Phd in Psychology shouldn’t  be  a  negative  point?I  wonder why  everybody  is  attacking  Harry for  that?Instead of  your excessive  amount  of  Envy,I  advise  you  to  read  his  books  and  try  to  learn  something about  SS implementation,regards  

Please  demonstrate  a  simple  case  study to  explain  TOC?How  to  encompass TOC with Lean-SS?I’m  confused ,thanks

Out-standing Explanation

Please  explain  the  diffirence between  long-term shift and short-term  shift, and the  role  of  the  1.5 shift in  this  dilemma? 

As  pretenders??

Yeah, you just are working with bad data from the get-go.  I think the previous poster was spot on…You really need a reliable, professionally applied and analyzed VOC instrument in place…there are many companies that do an excellent job of this for a fairly reasonable price…they will take your customer list, gather the data, regress it for…[Read more]

Wow….talk about a big fecal sandwich…before you take a bite, here is my 2 cents:

Balance Scorecard the thing first…if you dont know the fundamentals, buy the book.  You need to determine how to prioritize your quality efforts:  How are you defining success, What are you measuring so you will recognize when you are successful, What are t…[Read more]

You gotta do two things:

Determine what defects are occuring, where, and their impact on the business (costs) and the customer (customer satisfaction=market share)
Determine the cost of this poor quality (COPQ) as it pertains to these internal failures (defects before you ship) and external failures (defects after you ship)
You need to…[Read more]

How are you defining “best”?  It appears to be fairly simple to compare the accuracy of each method (%) as well as its precision (std dev).  Now use Coefficient of Variance (stddev/mean) to determine variability. 
Double check this, as I am making most of this up as I go along.  Good Luck.

Wow.  I have a few, but nothing constructive.

Its my understanding that DPMO can indeed to used as a weighted average.  Simply calculate it accordingly.  In addition, the DPU is a great alternative.  It is additive and thus, multiple measures from the different plants can be calculated and then averaged…DPU also allows you to determine RTY using the inverse log of your DPU…pretty slick an…[Read more]

Your welcome.  With due respect, you appear to be jumping ahead before root cause is known and without knowing how you intend to analyze the data you do collect. 
For example, take some time and creatively look for ways to move away from attribute data in your project Y and the follow-on analysis (ie days until breakage, hours of usage, et…[Read more]

Good luck.  I would pay attention to operational definitions (ie what does “broke” mean), units of  measure (use continuous as much as possible), and capture as many potential predictor variables as possible in data collection (type, model, breakage location, hinge location, user type, age of unit, etc). 

I have no idea what that means.

OK, let me say I didnt read your question, if you had one….way too long.  Ask a question, wax unpoetically else where.  But based on your subject line:
By basic definition, you can’t prove anything using inferential statistics without a stable, predictable process.  Lean it out.  Remove special cause.  Now welcome to AIC of DMAI…[Read more]
