A one point lesson (OPL) is a single page that teaches one thing, mostly with a picture: often the wrong way next to the right way. It is read at the machine in a few minutes and signed by each person who has been through it. The 20 examples below are sorted into the four usual types, with the mistake each one heads off and the picture that does the teaching.

How something works or what good looks like, so people can spot when it isn't.
Shows the gauge on the air supply with the normal range marked in green, and what to do when the needle sits outside it.
How to set the value, pull smoothly until the wrench clicks once, and stop. It also says not to use it to undo bolts.
Where the sight glass is, what the minimum and maximum marks look like, and who to tell when the level is low.
Each lubrication point has a colored tag that matches the color on the oil can, so the right oil goes in the right place.
Where the part number, revision and lot number are on the label, and how to check them against the job card.
One hazard and the one way to work around it safely.
Stop, isolate, lock and tag, then try the start button to prove the machine is dead before reaching in.
What to wear in the booth (respirator, gloves, coverall), and when to change the respirator filters.
Stop at the marked line, look both ways and wait for the driver to see you before you cross.
What the hazard pictograms on the drum mean and where to find the safety data sheet.
Feet apart, bend the knees, keep the load close and turn with your feet instead of twisting your back.
Written after something went wrong: what happened, how to spot it and what to do so it doesn't happen again. Usually a wrong (NG) and a right (OK) picture side by side.
A bracket went on back to front and was found at final test. The lesson shows how to tell the two sides apart and the check that now catches it.
A unit reached the customer with a hose clip missing. The lesson shows where the clip sits and the extra look the inspector now takes.
Painted parts were stacked face to face and scratched each other. The lesson shows the divided rack they now go in.
The line kept stopping for no clear reason. Dust on a sensor lens was the cause, so the lesson shows the lens and how to wipe it at the start of each shift.
Boxes went out with the last job's labels. The lesson shows how to clear the printer queue as part of every changeover.
Written after a change: the old way, the new way and what people now do differently.
The tools used to live in a drawer. Now each one has its own outline on a board at the station, and the lesson shows where each tool goes.
The fixture used to be held with four bolts. The lesson shows how to open and close the new quick-release clamp and how to check it is locked.
Work in progress now has marked squares by the machine, one per pallet. When the squares are full, the step before stops.
Fastener bins now have a card. When a bin is empty, the card goes in the post box and stores refills it.
Inspectors used to measure the slot with a ruler. Now there is a go/no-go gauge, and the lesson shows how to use it and where it hangs.
