A new guy learns by standing next to whoever's free that day. He gets half of it, nobody writes down what he was told, and three weeks later he's running a press on what he remembers.
Stan puts your SOPs, your safety rules and the basics of his machines on his phone the day he's hired. Short lessons, a test after each one, in English, Spanish or Portuguese. He finishes before he runs anything. For the hands-on parts, his supervisor signs off in the app.
You print every lesson he took, every score, every sign-off, with dates. One click.
