I need some help in conducting a MSA-
The process involves the measurement of plaster by use of a scoop- the spec is set at 260 +/- 20 and I dont think the process will be accurate enough - any suggestions on how i should proceed
First things first, be sure to clearly identify, document and train the operators on how the scoop is used. It is a heaping scoop, a level scoop, etc.
Have a device (a scale for weight, a container volume) which will provide enough resolution and which is accurate and repeatable.
Do a search in this forum, or use googles advanced feature and do a search for gage r&r (you can always try R&R, GR&R, etc.) selecting ".xls" as the filetype.
Granted, this is a really simplified explanation, but the study doesn't have to be a mammoth undertaking. Don't make it any more complicated than needed.
Just out of curiosity, if you don't mind. What is the application that it would require a GR&R on plaster?
