In the last chapter, I talked about how SPC doesn't happen overnight. And it does. Start slowly. Every existing customer of the Q-DAS software who now wants to delve deeper, but also every potential new customer, already has measurement data somewhere. And this can be analysed.
Then you can very carefully and cautiously save and display quality control charts to the user. Display! Do NOT alarm. Show the image during data recording. Or use the reporting system to send the last day's SPC alarms to just one of the key users so that they can view those alarms and decide whether they should have been alerted to the user in the future...
A defined period for analysis, so to speak! To build up understanding.
Then you can slowly activate the alarms. Maybe even just for the location chart (even if there is a chapter here that says that location charts make no sense without variation charts...). But for the beginning, to sensitise all users. And then at some point the variation charts...
And of course the "rest" was taken care of in advance! Is the measurement uncertainty small enough? Which characteristics need SPC? How large does my subgroup need to be? How often do I need to take subgroups?
In many projects with customers, this was a process that took years. Sometimes involving setting up the measuring devices, replacing the measuring equipment, sensitising the designers to their set "fear tolerances" and whether these really need to be so tight...
