Services and functions to maintain
Safe production, consistent quality and dependable delivery.
An industrial asset contributes to a process with operating limits, quality requirements and dependencies upstream and downstream. Assess impairment against the product or service being delivered, including the effects of reduced capacity, interrupted batches and changed operating conditions. Recovery includes confirming safe, stable operation and acceptable output.
Relevant assets and dependencies
- Production equipment, control systems, protective systems and operator competence work together.
- Electricity, water, heat, compressed air and other process services can create shared points of dependency.
- Materials, spare parts, specialist support and logistics affect the ability to maintain output or restart.
A shared utility loses capacity
A compressed-air system develops a fault that affects several production lines. Equipment-level alarms do not show the full effect on throughput, quality and restart sequencing.
Map the affected processes and remaining capacity, consider safe operating options and coordinate the intervention with production teams. Verify stable utility performance and product quality before restoring normal output.
This example supports discussion of the framework. It describes no measured result or prescribed operating procedure.
Decisions TAR helps inform
- Assess continued operation, reduced production, planned stoppage and repair against established operating limits.
- Consider the effect of an intervention on adjacent processes, product quality and delivery commitments.
- Assign restart authority and agree the evidence needed before returning equipment and production to service.
Evidence of the intended outcome
Select evidence that reflects the service, its agreed limits and the consequences of impairment.
- Production maintained or lost, considered alongside product quality and operating conditions.
- Inspection, process checks and restart authorisation records.
- Actual performance after intervention, including recurring defects and revised maintenance assumptions.
Record the baseline, assumptions and any remaining constraints. Review what the intervention achieved and use the findings to improve future decisions.

Industrial sites may operate their own energy plant, transport facilities and data centres. Their resilience should be assessed as dependencies of production as well as specialist assets.
