Production Performance Brief
Maintenance and Critical Spares for Water Bottling Lines
The most important spare is not always the most expensive part. Criticality depends on production impact, availability, repair time and alternatives.
Direct answer
How should critical spares be selected for a complete line?
Review point 01
Map assets to the production constraint
Maintenance priorities should consider which equipment can stop or degrade the whole line, including utilities and controls.
- Constraint equipment
- Single-point failures
- Shared utility assets
- Obsolescence and supplier lead time
Review point 02
Separate consumables from insurance spares
Routine wear items, scheduled replacement kits and high-consequence insurance spares need different stock and review rules.
- Usage rate
- Shelf life and storage
- Interchangeability
- Minimum stock and reorder point
Review point 03
Use history to refine the plan
Track faults, replacement time, repeat failures and production loss. Update preventive tasks and spare holdings from verified evidence.
- Failure code
- Mean time to repair
- Parts consumed
- Post-maintenance verification

Frequently asked questions
Answers are planning guidance. Project requirements and performance remain subject to confirmed data and agreements.
Should the supplier spare-parts list be accepted unchanged?
It is a starting point. Adjust it for site inventory, lead times, operating hours, skills, criticality and confirmed equipment configuration.
Do change parts belong in the spare-parts list?
They should be controlled, identified and stored, but their purpose and stock policy differ from wear and breakdown spares.
