    I am doing my certification, and have been stuck on this question for days.  Any assistance is appreciated!!!!        What order does this go in???

    Below are some of the steps a team took during the Analyze Phase.  What is the appropriate order?

    • State the root cause hypothesis
    • Conduct data and process analysis
    • Develop a fishbone diagram with the team
    • Conduct a 5 Whys on likely causes
    • Use data, observation or logic testing to verify causes

    thank you for any guidance!!!    -dave

    @blazn007 What do you think the answer is? Why or why not?

    The iSixSigma audience is helpful but they like to see that someone is putting in a good-faith effort on their own first.

    Thank you @katiebarry      Trust me, I think I’ve dug within every Green Belt resource there is.  I’m not looking for any short cut.  But, this is driving me crazy.

    Appreciate it!  :-)

    @blazn007 That may be, but you didn’t answer my questions.

    If you have done the research then you must have come up with an answer. What is that answer?

    And if you know you’re wrong, then what are you being told is the right answer?

    Do you have any guesses as to where/why you’re going wrong? If not, why are you sure you’re right? It’s not unheard of for an answer to be wrong so perhaps this is one of those times. Again, though, without explaining this to the iSixSigma audience, you are unlikely to get any response.

    I understand, and thank you for the guidance.

    My challenge is that, from what I have learned thus far, the 5 Why’s could be used at any point of any process development.  That way, you are always questioning all factors and paths, to ensure clarity on options. From those answers, one can develop the fishbone diagram. But again, that diagram could be a living/breathing diagram, so makes no sense to me that it’d be at a static place in any process.

    Around all that is the use of data observation and testing, and then, and then analysis of that testing.  Those two are static. But, the question is posed as if the other steps are as well.

    sorry to take up your time.  I’ll continue reading and figure it out.  It shouldnt be this difficult. thanks!

    oh my….what a silly exam question.

    Please know that there are a lot more analysis tools available and for them to mention “weaker” ones like Fishbone and 5-why (which are actually VERY related) is a shame.

    @blazn007 I have to agree with @cseider that this is a stupid question and poorly constructed.  Lets just walk through some logic. In most cases people have a hypothesis rattling around in their head but realistically you would derive that hypothesis from some pretty low level tools like 5why and fishbone diagrams. So lets say you do a Fishbone first and then do 5Why on your multi-voting result and based on that you derive a hypothesis. Once I have a hypothesis I would want to do some type data demographics and data analysis. Once I have done that I would go back and use data and logic testing to verify what my analysis produced (the word verify is pretty much an indicator it is the end).

    I have no clue if this is right or wrong in the eyes of someone who would ask such an inane question. Tell your instructor to start asing question that make sense or you won’t pay them.

    Just my opinion
