    I am looking for examples of gage r&r reports.  Once the gage testing is complete, how is the information presented to customer?

    Gauge R&R is use to check your Measurement system capability,
    so once you have completed the test, what actually you are interested
    is the %study var and %tolerance which generated by the Minitab.
    the guideline is both the parameter should be below 30% in order for
    you to conclude that your measurement system is ok. hope this help!!!

    In the DMAIC flow of events, it may be necessary to present the Gage R&R as something of great importance to the internal or external customer.  To present the results, try to simplify by showing (1)the item being measured, (2)the specified dimensions, and (3)the proportion of the width of the specifications absorbed by the variation of the gage.  Add a reference line showing either 20% or 30% as a boundary, and declare the measurement system “Good” or “Bad.”
    If the measurement system is bad, perform a DMAIC project on the measurement system.  Then, return to the first project.

    If you are doing it by minitab..best way is to copy the minitab output and present it to the customer, with some highlighting for % figures etc.
    If you are not using minitab then follow the format from QS 9000 manual..

    Hemanth,
    I agree with you to a degree, depending on the audience.
    If you have BB/GB’s who will understand the stats portion or if it is a technical group then I would use the entire Minitab output.
    If you are presenting to management (generally a type A personality) I would take only the graphs. It is difficult to picture exactly what the information is telling them and the graphs with the confidence intervals makes it much clearer (at least in concept). For the most part they want to know what it means in terms of results not the details of the analysis. The language of management is money you need to speak their language.
    Another thing you might want to consider is that when you present to management/type A personalities they will not sit still long before they feel the need to jump in (therefore the 10 reviews during training). Graphical representations transfer information quicker than text. Decide your most important points and how to move thhe information to them as quickly as possible. You may have used some tools that helped you but don’t add to the story you are trying to tell. Leave it out and have a backup file running in the background so if someone has that need to know you can get it quickly.
    Just my opinion.
    Good luck.

    Hi Mike
    Thanks for the reply..presenting graphical output from minitab is a good idea, I will use this info from now on in my presentations..
