Oh for Pete's sake, it's not like your shop is Exhibit A for manufacturing. There are more certifications available than machines on your floor, I'll wager.
Example (only ISO): https://certifications.thomasnet.com/certifications/glossary/quality-certifications/iso/
(only SAE): https://certifications.thomasnet.com/certifications/glossary/quality-certifications/sae/
You got a whole lot more to aspire to........
If you're not careful you'll crowd otrlt off his high horse.......
Me ISO, you not! Me better!
