How to Write a CIL That Actually Works
Most CIL programs fail not because operators don't care, but because the CIL itself is poorly designed. Too vague to be useful, too long to be completed properly, and too disconnected from what failure actually looks like on the line.
Here's what separates a CIL that drives real equipment care from one that becomes a box-ticking exercise.
What should be on a CIL?
A CIL point should exist for one reason: because neglecting it leads to a defect, a stop, or an accelerated failure. If you can't trace a check back to a consequence, question whether it belongs.
Good CIL points typically cover:
- Lubrication points — any fitting that requires regular replenishment, with a clear description of what good looks like (colour, consistency, level)
- Contamination checks — areas prone to product, dust, or debris build-up that affect machine performance or product quality
- Wear indicators — components that deteriorate visibly over time: belts, seals, guides, brushes, blades
- Fasteners and guards — anything that can loosen or shift and affect safety or machine condition
- Sensors and detection devices — photoelectric eyes, proximity sensors, encoders — checking alignment, cleanliness, and secure mounting
What doesn't belong: anything that can't be assessed in a reasonable time during a shift, or anything better suited to a planned maintenance task.
How to get operators to find defects — not just complete checks
The difference between a functioning CIL and a rubber-stamp round comes down to one thing: whether the operator understands what they're looking for.
A check that says "inspect conveyor belt" tells an operator almost nothing. A check that says "inspect conveyor belt for fraying edges, cracking, or tracking off-centre — attach photo if any observed" gives them a picture in their mind of what failure looks like.
For each check point, define:
- What normal looks like
- What abnormal looks like
- What to do if something's wrong
Reference images are powerful here. A photo of a clean, correctly lubricated bearing next to a photo of one that needs attention removes all ambiguity — and removes the excuse.
How to stop it feeling like box-ticking
A CIL feels like box-ticking when operators don't believe it matters. That belief usually forms early — and it forms based on what happens when they do flag something.
If a defect gets raised and nothing happens — no action, no follow-up, no acknowledgment — the operator learns that raising issues is pointless. After a few rounds of that, they stop looking properly and start completing checks from memory.
Three things change this:
- Actions get closed visibly. When an operator raises a defect, they should be able to see it move through to resolution. That closed loop is what sustains engagement.
- Standards get updated when operators suggest it. The person doing the round every shift knows when a check is wrong or outdated. Give them a way to flag it, and act on it — it signals that their input matters.
- Keep the CIL tight. A 45-minute round that nobody can complete properly in a busy shift will always be rushed. Better to have 15 checks that get done well than 40 that get skimmed.
Continual is built around exactly this. Reference images and videos sit alongside each check point, defects raised by operators are tracked through to resolution in-app, and the Proposed Changes workflow gives operators a direct path to flag when a standard is wrong — so your CIL improves over time rather than going stale.
