Control effectiveness should consider whether the control is appropriate for the risk, correctly implemented and working as intended.
The assessment should be supported by evidence wherever possible. For example, the existence of a fire door is not in itself evidence that it is an effective control. Its condition, specification, inspection regime, maintenance and role within the overall fire strategy may all be relevant.
Where effectiveness cannot be demonstrated, this uncertainty should itself be recognised and managed.
