    Question on a BB test I receicently took I disagreed with the answer, how would you have answered?
    Q.  If all my bars are equal in my Pareto would you –
    1.  pick any bar to work on
    2.  use the Why-Becasue tool
    3. stratify the data using a different y axis
    4.  revisit the team charter
    Thanks for the help.

    Jim,
    This is a subjective and tricky question with a lot of why’s. There should be stated some assumption or something. 
    For this question the your, instructor might answer (1.0 pick any bar to work on.)
    For us BB,  you need to always verify your data if it was correctly taken else your analysis migth be misleading. Thus, I will answer (2.0) since having all pareto bars with equal count is not normal and I haven’t seen such in my 8 years BB experience.

    Change the y-axis.  If you want to have an impact on your business, you need to find where the pareto is.  That’s where you will get the most leverage for deciding what to correct. 
    Pareto always exists, you jeust may need to do some work to find it.
    It kind of bugs me that people call  “Pareto chart” what is really nothing more than a rank order bar chart.   Much more significant is a Pareto distribution, that indicates a source of leverage.  There really are vital few, and many trivial.
