Verification and Continuous Improvement
Core concepts
Verification asks whether controls and management-system processes are working as intended; continuous improvement asks whether they are getting better. Tools include inspections, audits (first-party internal, second-party supplier, third-party certification), observations, monitoring and measurement, trend analysis, and management review. Leading indicators measure preventive activity-training completion, corrective-action closure, near-miss reporting, audit findings closed on time. Lagging indicators measure outcomes-injuries, illnesses, spills, citations. Corrective action should address root cause, assign ownership and due dates, and verify effectiveness. Data quality matters: consistent definitions, complete reporting, and appropriate sampling. Improvement should be planned and measured, not assumed from activity.
Traps
- Treating a low injury rate as proof that risk is controlled; reporting may be incomplete.
- Confusing verification (did we do it?) with validation (did it achieve the intended result?).
- Closing a corrective action when the paperwork is filed rather than when effectiveness is verified.
- Relying only on lagging indicators to drive improvement.
- Assuming an audit is a consultation or that audit findings automatically equal legal violations.
Worked example
A site sets an objective to reduce hand injuries. A weak objective is “improve safety awareness.” A stronger one is “reduce recordable hand injuries by 30% within 12 months by installing guards on five presses and completing 100% of corrective actions within 30 days.” The second is specific, measurable, achievable, relevant, and time-bound, and it can be verified. Rule of thumb: if you cannot tell whether an objective was met, rewrite it.
