The Broken Thermometer Problem
There's a version of a contractor safety system that looks excellent on paper.
High training completion rates. Inspections done on schedule. Toolbox talks logged every morning. Reams of procedures for every craft.
And then there's a loss event. Maybe major property damage or a serious injury. And when you go back through the records, everything was compliant. Everything was documented. The boxes were all checked.
A thermometer reading below zero doesn't make it cold outside. It just means your measurement tool isn't telling you the truth about conditions.
You can measure the wrong things with perfect precision and not be one bit safer for it.
Two examples worth sitting with.
Training completion rates don't equal competence.
Completion tells you someone was present for the training. Competence only shows up at the work face — the worker applying knowledge and skill under actual field conditions. Those are not the same thing, and one of them is much harder to measure.
Inspection counts don't equal hazard elimination.
You can complete every scheduled inspection and still do a poor job of finding and treating hazards. The count measures that inspections happened. It says nothing about whether they were effective.
The deeper problem: Goodhart's Law
The deeper problem is what economists call Goodhart's Law: when a measure becomes a target, it ceases to be a good measure. The moment you attach an incentive to a metric, you create pressure to manage the metric rather than the underlying condition.
Near-miss reporting rates get gamed by over-reporting trivial observations that bury real signals in noise. OSHA and DART rates get managed by ensuring injuries become non-recordable. Both happen regularly in organizations that consider themselves reasonably mature.
The real question
The question isn't whether your organization tracks leading indicators. Most do. The question is whether what you're tracking has a genuine, demonstrable connection to how incidents actually occur in your specific environment.
Before you add the next metric to your dashboard, answer this: how does this indicator connect to incident prevention in our organization — not in general, not because a competitor tracks it, but based on our own incident history and operational context?
If you can't answer that clearly, you're measuring noise.
The most valuable leading indicators don't measure whether something was done. They measure how well it was done. That shift — from activity to quality — is where contractor safety systems start to actually move the needle.
