Critical Spares Analysis
Spares are fundamental to maintenance and can be a source of major delay and loss associated with poor spares stocking strategy and poor spares management. Spares can cost a company a significant amount if there are too few and if there are too many held in stock.

We have also found that poor spares management during ongoing maintenance can lead to many millions of dollars in spares wastage.
Deciding on what spares and what stocking strategy is not as simple as just getting the list of required spares from the OEM.

- Site stocking strategy
- Catalogued parts as order on demand
- OEM or supplier held key components under parts holding agreements or
- Do not stock component and risk mitigation plans
