Improving Spare Parts Availability Through Proactive Inventory Management

Reliable spare parts availability is therefore an essential part of maintenance strategies, particularly in Ireland’s pharmaceutical, medical device and industrial manufacturing sectors. Proactive inventory management helps companies maintain appropriate stock levels of critical components while avoiding unnecessary inventory.

Why Traditional Minimum Stock Levels Are Not Always Sufficient

Many companies manage their spare parts inventory using fixed minimum stock levels. When the available quantity falls below a defined threshold, a replenishment order is triggered.

This approach works relatively well for regularly required wear parts. However, it has limitations when dealing with components that are rarely needed but highly critical.

A specialised variable frequency drive, for example, may not be required for several years. However, if it fails and the replacement lead time is several weeks, its absence can have significant financial consequences.

Several factors should therefore be considered to ensure reliable spare parts availability:

• Criticality: What impact would the absence of a spare part have on production operations?
• Replenishment lead time: How quickly can a replacement component be delivered?
• Usage history: How frequently has the spare part been required in the past?
• Equipment inventory: How many machines use the component?
• Inventory value: How much capital is tied up in maintaining the stock?

Only by combining this information can companies develop an economically viable inventory strategy.

Digitally Recording and Reliably Managing Spare Parts Inventory

Proactive decisions depend on knowing actual stock levels. However, discrepancies frequently arise in spare parts warehouses containing thousands of different items due to undocumented withdrawals, incorrect storage locations or manual booking errors.

The COSYS Inventory Management Software helps companies digitally document goods receipts, material withdrawals and stock transfers. Employees record spare parts directly at their storage locations using barcodes and mobile data collection devices.

For larger spare parts warehouses, devices such as the Zebra MC3400 or Datalogic Falcon X60 are suitable options. For smaller storage areas and mobile maintenance teams, the compact Honeywell CT37 can provide an alternative.

In addition, COSYS MDE Services cover device configuration, repairs and replacement devices, while Mobile Device Management (MDM) enables centralised administration of the devices in use.

Which Spare Parts Should Always Be Available?

Not every spare part needs to be permanently stored in a company’s own warehouse. The key is a risk-based inventory strategy.

Standardised fasteners or consumables that can be delivered at short notice can often be reordered according to demand. However, maintaining permanent stock may be economically justified for machine-specific control modules, specialised motors or safety-critical components.

Companies should therefore classify spare parts according to their operational importance and regularly review their inventory strategy.

Availability at other company locations should also be considered. If an urgently required component is already available at another production facility, an internal stock transfer may be faster than purchasing a replacement.

Business Intelligence Identifies Changes in Spare Parts Demand

A basic inventory overview shows which spare parts are currently available. However, understanding how demand develops over time is equally important for proactive planning.

With COSYS Business Intelligence, recorded stock withdrawals, inventory developments and item movements can be analysed over extended periods. This allows maintenance and warehouse managers to identify, for example, when certain wear parts are required increasingly frequently or when individual components remain unused for unusually long periods.

Such analyses can indicate changing maintenance requirements, excessive safety stock levels or increasing demand for spare parts.

For more advanced demand forecasting, historical consumption data can be combined with additional information such as maintenance intervals, equipment operating hours and planned maintenance activities, provided that this data is available and appropriately integrated.

This creates a more reliable basis for procurement decisions without relying exclusively on fixed minimum stock levels.

Ensuring Inventory Accuracy Through Regular Stock Checks

Even carefully planned spare parts inventories become less reliable when recorded stock levels do not match the actual quantities available.

Cycle counting allows spare parts inventory to be checked regularly throughout the financial year. Particularly critical or high-value components can be prioritised for more frequent checks.

This reduces the risk of discovering missing spare parts only when urgent repairs are required.

Conclusion: Managing Spare Parts Supply Reliably and Cost-Effectively

Proactive inventory management does not mean keeping as many spare parts in stock as possible. Instead, the objective is to maintain the right components in appropriate quantities and base procurement decisions on reliable data.

COSYS combines digital inventory management with mobile data capture, suitable hardware, technical services and Business Intelligence. Companies can gradually digitalise their spare parts warehouses and continuously improve their inventory strategies based on actual material movements.
