An OPL is a short visual lesson that teaches one focused point about knowledge, improvement, trouble prevention, safety, quality, or equipment care.
Definition
An OPL, or One Point Lesson, is a concise training document or visual aid that teaches a single practical point. It usually fits on one page and uses photos, sketches, brief text, and before-after examples so operators, technicians, and team members can learn at the point of use.
OPLs are common in TPM, standard work, safety, quality alerts, and Kaizen sustainment because they convert local learning into reusable knowledge.
History
One Point Lessons became common through TPM and shop-floor training systems. They support autonomous maintenance, focused improvement, and daily management by making small lessons easy to create, approve, teach, and refresh.
When to Use
Use an OPL when one specific lesson needs to be shared quickly: a defect mode, inspection tip, lubrication point, safety precaution, setup trick, abnormal condition, or improvement standard. Use a longer SOP or job instruction when the task has many steps or high risk.
Step-by-Step
- Define the single point the learner must understand or do.
- Choose the OPL type: basic knowledge, improvement case, trouble case, safety, quality, or maintenance.
- Use a clear photo, sketch, or marked-up example.
- Write brief action-oriented text.
- Review accuracy with the process owner or subject expert.
- Teach the lesson at the point of work.
- Confirm understanding through observation or teach-back.
- Store and revise the OPL when the standard changes.
Examples
- TPM: A photo shows the correct oil level window and abnormal low-level condition.
- Quality: A visual comparison shows acceptable and unacceptable surface defects.
- Safety: A short lesson explains the pinch point created during changeover.
Common Pitfalls
- Trying to teach too many points on one sheet.
- No ownership for review and updates.
- Using vague photos or excessive text.
- No confirmation that people learned the point.
- Letting OPLs conflict with the official SOP.
- Posting lessons without removing outdated versions.
