Use the numbers your plant tracks
Manufacturing runs on metrics, and hiring managers read resumes the same way. OEE, rejection rate, cycle time, downtime, scrap and cost savings are the language of production and quality roles - use them in your bullets.
'Raised OEE from 68% to 81% through SMED and preventive maintenance' shows the problem, your method and the result. It's far stronger than 'Responsible for production line efficiency'.
