Learning objectives
After this lesson, you should be able to
- Distinguish leading from lagging indicators
- Avoid treating a single score as the whole safety system
- Create an evidence-based review cadence
Pair outcome and process signals
Crashes, violations, and claims are lagging outcomes. Inspection completion, defect closure time, training follow-up, speeding events, and log-review quality can reveal risk earlier.
- Define each measure precisely
- Segment by exposure and operating context
- Investigate causes before assigning corrective action
Scores require context
Public and internal indicators can support questions, but they should not replace source review, due process, or a complete safety-management analysis.
Apply the decision protocol
Use a fictionalized or fully permissioned operating scenario. Build five columns: observed facts, supplied facts, assumptions, controlling sources, and unresolved questions. Do not advance a consequential action while a required fact, authorization, qualification, or safety condition remains unresolved.
- Demonstrate: Distinguish leading from lagging indicators
- Demonstrate: Avoid treating a single score as the whole safety system
- Demonstrate: Create an evidence-based review cadence
- Name the decision owner, evidence standard, stop condition, and next review time
Practice with evidence
Create a one-page decision record and ask a peer to challenge the source, version, applicability, missing facts, incentives, and proposed communication. Revise the record rather than defending the first answer. Preserve the initial and corrected versions so an editor can see what the exercise actually taught.
- Cite every externally verifiable claim
- Separate uncertainty from error
- Escalate beyond the lesson's stated competence boundary
- Remove private, proprietary, or personally identifiable information
Correct and transfer the learning
After the scenario, compare the decision to the current source and the stated objective. Record the misconception, the evidence that corrected it, the operational control that would prevent recurrence, and the conditions that would require the answer to be researched again.
Knowledge check
Why combine leading and lagging measures?
Reveal the answer
Leading measures can expose weakening controls before serious outcomes, while lagging measures show what already occurred.
Together they support earlier and more grounded intervention.
