  • It would be great if you could forward to me as well at [email protected].  Thank you in advance!

  • At peak time we run 16 busses across 5 terminals with 2-3 designated pick up spots per terminal.  We have14 busses run in set circuit loops with 7 clockwise and 7 counter clockwise (takes about 30 mins for an entire loop including loading and unloading of passengers) while the other 2 busses are direct between our two busiest terminals.  The 2 two…[Read more]

  • Gray,
    Thanks for your response.  And you are correct that our goal definitely isn’t one of maximizing utilization.  To maintain the 15 min headways, we probably couldn’t cut down any busses regardless of whether we carry 100 people a day or 10,000.  We are constrained by the distance between terminal and the use of CNG busses that don’t go ne…[Read more]

  • Thanks to all of you for your responses.  The application is in a feed mill that produces over 4500 tons of feed per week.  We are attempting to find and control shrink of ingredients.  It would be nice if output equaled input as one response suggested – thus the concern for shrink.  I believe that Chad’s response may work for some ingredients but…[Read more]

  • Thanks all for the input. 

  • Thanks to all for the input.  I appreciate it.

  • Robert:
    I am currentky in finals week at our school, but will get back to you with results from your suggestions.
    What is ASA?  American Statisticians Association?

  • Robert:
    Thanks for the ideas and observations.  I thought I scoured the web during the review of literature looking for projects like mine.  I did not come across yours.  Is is out there?  Can it be accessed?
    I was naive to think I was breaking new ground on this topic, but it looked that way.  I will get back to you re: the progress I make with…[Read more]

  • TVI-
    Yes, there is a wealth of information about transactional lean projects, from selection to control. We  have learned much from these and other sources. And we have a strong lean transactional component in most of our Six Sigma blended learning projects (with good results.)
     However, our new challenge is aligning and managing our core busine…[Read more]

  • I think yoiu may be asking the wrong questions. Personality typologies may not be as germain to 6s support and buy-in as “operating style” and “change agent style.”  There is a 30+ year study by Hersey on Situational Leadership that makes a compelling case for the effects of operating style on group performance. Also, Tuckman’s 4 steps of ch…[Read more]

  • Dean replied to the topic Regression Equatiuon in the forum General 18 years, 7 months ago

    If the correlations between the variables are changing at changing rates, then cubic or quadratic equations may show a better fit with the data than linear, which assumes a constant rate of change. Cubic and quadratic formulas are important to researchers because they inform us when complex or changing behavioral trends are at work. These are…[Read more]

  • Dean replied to the topic Employee retention in the forum General 18 years, 7 months ago

    It can be very difficult to predict and calculate the real cost of lost employees until they are long gone and the effects are more visible, and even then an accurate accounting of the true costs can be murky and debatable. My 1st rule of thumb is remembering the prime directive is prevention not accounting and taking credit. If you know a…[Read more]

  • Vincent,
    The economic value of doing COQ is not in fleshing ever deeper into possible sub-metrics or categories, but in “estimating” the four main categories of CQO (prevention, appraisal, internal failure, external failure) to obtain a certain view of the quality management function in the firm of how these four factors are “generally”…[Read more]

  • Dean replied to the topic BMG Master Black Belt Training in the forum General 19 years ago

    JB,
    Like anything eles, what you put into the MBB program is what you will get out of it?  Fortunately for myself, I have applied the BMG MBB principles with great success with huge cost savings for a very large company, and I am not yet complete with the program.
    Interestingly enough, last month I received a flyer in the mail from a “Six Sigma[Read more]

  • Dean replied to the topic BMG Master Black Belt Training in the forum General 19 years ago

    I am in the program now. In my opinion it is the “Harvard” of MBB programs out there. It is more challenging than other programs, but much more effective.     

  • Ecole,
    Have you tried both test approaches? With software, they are fast operations. Often differing approaches in statistics reach the same conclusions if the data speaks sufficiently. If the 2 approaches give oposing results, then you have to resolve the debate and achieve higher precision. Do not sweat the precision question unless you…[Read more]

  • Dean replied to the topic Sales Quote Hit Ratio in the forum General 19 years, 2 months ago

    Beware of chasing efficiency where effectiveness is king! Which is more important to your firm, improving the hit ratio 50%, say from 1:8 to 1:4, or increasing sales and profits 50%? Most CEO’s will choose the latter. Too many consulting studies choose the former.
    Lots of value building activity in marketing will naturally result in a…[Read more]

  • Dean replied to the topic 6 sigma buy-in in the forum General 19 years, 2 months ago

    There are 2 common errors in improvement initiatives that have been around since the beginning of time: under-engineering, and over-engineering.
    Under-engineering is when changes are made with insufficient data. Just because many intuitively knew of some causes does not necessarily constitute carnal or actionable knowledge of the causes. If you h…[Read more]

  • Dean replied to the topic Sales Quote Hit Ratio in the forum General 19 years, 2 months ago

    As a marketing VP in metal fabrication firms I did similar studies several times. Each time there was a knee jerk desire by many involved to make this into a “sales person process” study, or a “cost reduction study” when in fact this kind of investigation is more of a “marketing process” study. The distinction is important.
    Typically, as Deming…[Read more]

  • Dean replied to the topic strategy? in the forum General 19 years, 2 months ago

    The first priority of such large task is program perpetuation, which requires cooperation, participation, and sufficient early wins to make the program justifiable and supportable for all involved. Keeping your eye on this ball is your first order of business, whereas the means of how you get there are your second order issues. It is essential yo…[Read more]
