One page that teaches one skill.
Use it to teach a single skill or fact at the point of use. Fill in why it matters, the key points and what to watch for, and it lays out a clean one-page lesson.
Keep it to one point and one page, mostly pictures. Add a photo or sketch on paper, then post it at the point of use.
A one point lesson (OPL) teaches a single idea on one page, mostly with pictures, in a few minutes at the workplace.
An OPL titled 'Correct belt tension' shows a photo of a belt deflecting 10 mm under thumb pressure (correct) next to one deflecting 25 mm (too loose), with the check frequency and who to call if it is out of range.
A short, visual lesson on one topic, written ideally by an operator or technician for their peers.
Widely in TPM (Total Productive Maintenance), 5S, safety and quality training.
