  • There are several traits that (based on my experience and observation) tend to make a person more likely to succeed in the Black Belt role:
    1.  A good mathematical (or quantitative methods) background.
    2.  The willingness to learn new concepts and the gumption to challenge the status quo in the application of those new concepts.
    3.  A STRONG de…[Read more]

    I had the distinct pleasure of hearing a gentleman lecture on Shanin concepts using decision trees in the first week of my Master Black Belt training.  He is at Ford Motor Company in Dearborn.  I will try to get through to him and direct him to the site so he can tell you what he knows.  Mike has provided some excellent insight.
     

  • What is it exactly that you are doing?

  • Jim Johnson replied to the topic DOE Topics in the forum General 19 years, 10 months ago

    Hello.  If you look to the right of this page you will see a section entitled, “Tools & Templates”.  Under this section of the web page you will find a section on DOE containing about twelve articles.  Some will be more applicable to your circumstance than others.
    I hope that this helps.

    Hello.  We use a paper helicopter as the basis for the DOE instruction.  There are three variables:  Wing Length, Body Length and Body Width.  A variation also can include using or not using a paper clip.  This works pretty well for Green Belt level understanding and doesn’t take nearly as long as the catapult experiments typically do.

    In a word…..NO!  The tools that are applicable to process (manufacturing) projects are just as applicable to transactional (business) projects.  Many times, you have to find the right tool for the specific task you are attempting to accomplish. 
    My Six Sigma experience is solely in the transactional side of the house and I have used al…[Read more]

  • This is one of the best applications for the methodology in the business (transactional) side of the house.  Go for it!
     

  • Jim Johnson replied to the topic FMEA vs. CE in the forum General 19 years, 11 months ago

    I agree with Mike says.  I would like to ask a clarifying question:
    Are you asking about the C&E matrix or the C&E diagram (Ishikawa Diagram)?  The distinction between the two for me is the view of the criticality of inputs on specific customer concerns (outputs).  This gives some quantification to VOC.   It is useful in the Measure phase to dete…[Read more]

  • I am pretty cretain that America Express used the methodology at one point.  I am not certain what there current state of deployment is.

  • I think that learning Six Sigma to the point where it would be truly beneficial would not work very well given the parameters that you have outlined.  I say that for a couple of reasons:
    1.  Without a project to apply the priniciple to it is simply an academic exercise.
    2.  The true value of Six Sigma is that as you deploy it into an or…[Read more]

  • The control limits are statistically defined as 3 standard deviations above and below the mean of the data sampled.  In the case of the X-bar chart, the UCL/LCL is 3 STD DEV above/below the average of the sub-groups of the data.
    To answer your question (I think) you would always use the UCL/LCL on the chart where it appears.  It exists to d…[Read more]

  • Jim Johnson replied to the topic Retail Sales in the forum General 20 years ago

    I am aware of some discussion on this forum concerning the Retail sales industry.  I think that the important thing to remember is that the focus is on what is critical to the customer.  If you stay focused on that in defining your defects, you should have some great success.

  • Jim Johnson replied to the topic Six Sigma IT in the forum Software/IT 20 years ago

    From most of the conversation that I have seen on this website, the real challenge in applying Six Sigma to IT is the same challenge that we are all faced with……What is a defect?
    I have seen two repeating examples of IT:
    1.  Lines of incorrect code in software development.
    2.  Downtime (or the frequency thereof) in a network, mainframe, s…[Read more]

    Are you a full-time student?  By that I mean, do you work anywhere where Six Sigma has been selected as the Business Process Management mehtodology?  If you have, then the other comment is absolutely correct…..you need to find a project!  You can learn all about Six Sigma by reading, however, no one who really understands the methodology is go…[Read more]

  • Jim Johnson replied to the topic Greenbelt Program in the forum General 20 years ago

    First of all, congratulations on your selection to attend Green Belt training.  By being selected you are regraded very highly by your organization.  In terms of how to measure forklift accidents, I would start with the company’s safety office.  They undoudtedly keep statistics on accidents involving workers.  A second place to find data would be…[Read more]

  • Now, I understand better what you are attempting to do.  My suggestion is to gather the top minds in the organization and conduct two brainstorming sessions:
    1.  A session to define the categories.
    2.  A session to finalize the placement.
    This will get it done quickly and by involving everyone you will have consensus.  Remind the group that con…[Read more]

  • It appears to me that the speed at which the steel tube is machined makes the process different in some way.  Is this truly the same process? (regardless of how it is viewed).
    If it is the same process, then you need to make a combination measurement.  If they aren’t the same, then you need to separate them
    It may be that I am oversimplifying t…[Read more]
