What a critical control verification should record

A tick in a box confirms that someone looked. A useful verification records what they saw, and whether the control would have worked.

A verification is only as useful as the record it leaves behind. This briefing outlines what a field verification of a critical control could capture so that leaders can read the results over time.

A control that is present can still fail

A control can be present and not in working condition, or in working condition and not used as designed. A verification that separates the three gives a leader more to act on than a single pass or fail.

Overdue verifications

Overdue verifications are a condition of the system, not a judgment of the people who own them. The exhibits use illustrative values only; they demonstrate the format, not a result.

Exhibit 2 Illustrative data

In this illustrative site, only energy isolation shows a steady fall in completed verifications

A backlog concentrated in one control is a different problem from a backlog spread across all of them.

The current report

The controls that prevent a fatality

Many operations have spent a decade driving recordable injury rates down. This report asks whether the controls that prevent a fatality have improved at the same pace, and how a leadership team would know.
