Why a consolidated report is not yet comparability
When head office asks plants for indicators, the numbers arrive on time. The trouble starts with interpretation: plant A records every cut, plant B only cases needing medical treatment, and plant C keeps two registers because that was easier after a merger.
The same applies to corrective actions. 'Closed' means 'done and verified' in one plant and 'handed over for execution' in another. A CAPA timeliness indicator then compares two different things.
The third dimension is audits. If each plant uses its own question set, 92% here and 78% there says nothing about the difference in safety — it describes a difference in questions.
