19 CROSSED MSA STUDY, NON-VALID
19 CROSSED MSA STUDY, NON-VALID
In the 19th Minitab training tutorial, we are back in the final assembly of Smartboard Company. Analogous to the previous training unit a crossed measurement system analysis will also be carried out, but with the difference that in this case we will get to know a measurement system, that is to be classified as an unacceptable measurement system in terms of the standard specifications. The core objective of this Minitab tutorial will be, to work out the appropriate procedure for identifying the causes of the inadequate measurement system, on the basis of the existing poor-quality criteria. In this context, we will also get to know other useful functions for day-to-day business, such as the creation of the Gage R and R study Worksheet layout for the actual data acquisition as part of the measurement system analysis, or the very useful graphic „gage run chart“, which is not automatically generated by default as part of a measurement system analysis. We will see, that we can generate this measurement run chart very easily and thus obtain further additional information, in order to derive specific improvement measures for the non-valid measurement system.
