How to define process sampling frequency?---How often should we sampling inspect the product and plot SPC chart?

Hello everyone:
Here is the 1st time to post a thread in this forum. I appreciate your kind response and your warm guidelines.


I work in power supply factory as QA engineer, our SPC implementation for a long time for some testing posiiton, mainly on failure rate (P chart). Someone found our SPC sampling frequency is not reasonable since we collect data is not on time (once per day for most of position in SPC plotting) what I think is is there any standard or guidelines to specify the appropriate data collection frequency?

Thanks in advance ~~~

There is a lot of good information available on "sampling."

An advanced search on "Sampling Plans" revealed this.

Hope this helps.
