    I am trying to prepare for the balck belt exam …. and I have a set of questions without answers that I am trying to use in helping me prepare for the exam …. I have no idea what is the answer for the following question …. can u please help.
     
    Using the SIPOC framework as context, which of the following statements applies when attempting to understand the key X’s that drive Y?
    a)    X corresponds to Input and Output measures, Y corresponds to Process measures
    b)    X corresponds to Process and Output measures, Y corresponds to Input measures
    c)     X corresponds to Input measures, Y corresponds to Process and Output measures
    d)    X corresponds to Input and Process measures, Y corresponds to Output measures

    I would think the answer is d. Typically a Y is called a response, output, or dependent variable. Your independent, predictor, or explanatory variables are usually inputs or Xs … a good process is a predictor of getting the outcome you want, your Y.

    I too think the answer is D
    Supplier —>Input—->Process—->Output—>Customer
    X would be ur input and Y would be ur output and the process is the one which transforms your Input to Output. So your X’s are key variables that effects the output. Hence I would go for D.

    Ok guys ….. you got the same answer as I did …. now lets try these questions:
    1. One use of Sigma measures is to:
     
    a)    Measure correlation between process and output variables
    b)    Compare process performance before and after improvement to qualify the amount of improvements made
    c)     Achieve any desired level of process improvement
    d)    Achieve greater than 5 Sigma performance for a process
     
    2. A Unit has:
    a)  Only one opportunity for a defect
    b)    No opportunities for defects
    c)     One or more opportunities for a defect
    d)    Six Sigma opportunities for a defect
     
     
    3. What is the main goal of the Control step?a)  Sustain the process improvements made by the improvement teamb)  Teach a process owner how to handle defects
    c)  Train all process workers to identify defects before they reach the customer
    d)    Mandate measurements on all output measures of the process
     
    4. Which of the following is true?
    a)  Specification limits are defined by the process ownerb)  Control limits show current process capabilityc)  Specification limits are the same as control limits for processes which are operating at 6 Sigmad)  Specification limits are statistically derived from process
     
    I believe the answers are:
    1) b
    2) d
    3) a
    4) d

    I think 2 is c … d doesn’t make a lot of sense to me … what does that mean …
    Personally, I don’t like any from 4. Your spec limits should be from your customer – internal or external … a control limit comes out of the process …

    I know what you are saying ….. I got these questions (actually like 30 pages) froma friend as a aprt for some sort of practicing for the BB certification.
    I hope that exam questions are not vague like the set of questions I am trying to solve.
    And actaully one of the questions that I am trying to find answer for right now is how to calculate the number of bins required to develop a histrogrma from discrete data ranging between 100 and 16200?!!

    4 is B
    i would like to know how did you arrived at D in question 2
    i think its C, even at six sigma you still have probability of .00034 for defect to come in, the opportunity is still there
    please elaborate if am wrong

    Actually I beleive the answers are :
    1. C
    2. C (You are right)
    3. A
    4. B (You are right)

    hey just a request,
    do you have some kind of question bank from ASQ etc for preparation, can that be mailed as soft copy etc.
    i would like to attempt and see where i stand, though recently cleared certification of my organisation besides hands on exp of mentoring more than 60 projects (GB, YB, BB combined)
    would really appreciate that
    rgds,

    I have a soft copy. Email your address to [email protected] and I will be happy to send it to you.  They are not ASQ questions.
    But it is only questions with no answers …. so you have to figure them out yourself … I have answered most of them , so you will see my answers on the papers also.
    Here are two more questions that I do not know how to answer and I would really appreciate your help:
    1. Which statement describes a critical deliverable of the Control Step?a)  A list of Operational definitions for all baseline measuresb)  A box plot for each continuous variablec)  A standardized process which is documentedd)  A Pareto Diagram
     
    I believe the answer is D
    2. How many bins are required for a histogram for a column of data with 150 entries (minimum is 100 and maximum is 16100)?! What formula do you use?

    answer to your question number 1 is documented standardised process
    second : let me get back to you on that
    not able to send mail to your personal id from my official one
    please mail it to [email protected]
    thanks

    The answer is (d) because its ultimately the input measures and Process measures that lead to the Output measures ie Y. Traditional equation of Six Sigma methodology is Y=f(x).

    I agree that it is D.

    Just go thru the material.. they have given how to construct the histogram.. and u can try plugging ur values..
    Good luck and let me know if this helped
