What is Parts Inventory Management?

Parts inventory management has always been a critical and complex challenge. Having the right part in the right quantity at the right time and in the right place requires planning, precision, and balance.

How to Use a CMMS for Spare Parts Inventory

The parts management tools offered by an effective computerized maintenance management software (CMMS) are a vital part of running a successful maintenance storeroom. eMaint’s parts management software simplifies tracking parts across storerooms worldwide and helps improve inventory accuracy. Organizations can set-up reorder points to track parts and auto-generated purchase orders.

With a CMMS, you can eliminate data entry and duplicate data with barcoding. Use barcodes and QR codes to scan and view part records instantly on a tablet or mobile device, and your team can use parts kitting to issue or return multiple parts with a single item number.

5 Techniques for Better Parts Inventory Management Strategy

1. Categorize your parts inventory

  • Active parts inventory (10 or more used each month)
  • Commodity parts (1 or more used each month)
  • Rarely used parts (fewer than 1 used each month)

When stocking parts inventory, consider factors including lead time, consumption rate, the costs associated with storage, and the potential costs and consequences that would be incurred if you did not have a needed part.

2. Set agreed-upon parts stocking and reorder points

This can help you avoid a feast-or-famine scenario where you have excessive parts inventory — or not enough. Standardize your methods for determining when and whether to stock a part — and in what quantity. Using consistent criteria to make parts inventory decisions can streamline the process, make it easier to identify priorities, and make communicating decisions easier.

3. Improve your supply chain management

Materials providers, shipping partners, and other parties directly impact your spare parts inventory. Though you cannot singlehandedly eliminate supply chain issues, you can take steps to optimize your relationships with your suppliers and shippers. Good two-way communication is essential. Track lead times using a parts inventory software to identify potential slowdowns or bottlenecks.

4. Use data to drive parts inventory decisions

Start with usage probabilities and optimize your parts inventory over time. Parts inventory management software goes beyond spreadsheets to integrate with other tools, reduce manual data entry, and make tracking easier and more accurate.

5. Ensure inventory accuracy

Conduct a cycle count to match your physical parts inventory with your inventory records. Cycle counting is a method designed to fit into your normal operations. A parts inventory software solution makes accurately tracking your inventory easier.

There are multiple inventory accounting methods. A first in, first out (FIFO) strategy is important if your inventory includes any parts or products that have limited shelf lives, such as chemicals or pharmaceutical ingredients. Track all of their expiration dates in parts inventory software to avoid spoilage.

Material management is a storeroom technique for parts inventory management. It governs how organizations plan, organize, and control the flow of materials from purchase to delivery. The mission of any materials management program is to keep the right parts in the right quantity, at the right location and time, with the right level of quality at the lowest possible cost.

Worker Roles for Inventory Parts Management Success

The purpose of the maintenance storeroom is to house materials in a safe, clean, secure, and organized environment. As a result, three primary aspects make up the materials management process:

  • Acquisition – Parts procurement (right parts, right quantity, right quality, lowest total cost)
  • Control – Stores
  • Movement – Logistics (right place, right time)

Planners generally trigger materials requisitions, determining the specific materials needed. They determine items, quantities, and dates for each work order. Procurement personnel is responsible for ordering exactly what the planner needs from approved vendors. Vendors provide parts that meet prescribed specifications. After delivery, personnel properly handle and control items in the warehouse area until needed in the field. At that point, logistics personnel arrange materials movements to the final destination.

In most organizations, maintenance storeroom personnel complete material movement, which means that Logistics and Stores are the same teams. Stores teams embed in the middle of the material flow, so they can affect every one of the elements of the mission.

Potential Pitfalls of Parts Management in the Maintenance Storeroom

There are a few unsuspected difficulties when managing a maintenance storeroom. These pitfalls include having the wrong parts in the wrong quantity, parts in the wrong place, delivered at the wrong time, and/or in unacceptable condition. Costs can increase significantly as well. In other words, to avoid these issues and successfully set up and maintain a storeroom, all team members must fulfill their roles and execute their responsibilities consistently and accurately.

Critical Success Factors for a Parts Management Strategy in Your Storeroom

  • Physical planning
  • Infrastructure – The condition of the maintenance storeroom facility itself is a fundamental challenge — a storeroom in poor condition risks exposure to the elements, which can degrade the quality of the materials.
  • Location – Too much distance between the storeroom and end-users can cause delays, damaging or losing items in transit.
  • Accessibility – Based on assessments, as many as half of all maintenance departments have an “open” storeroom plan, where the “honor system” is in effect. Educate your employees on adequate controls and procedures. Above all, put controls in place to handle, manage, and check-out materials properly.
  • Physical layout – Optimal materials flow is crucial to the ideal storeroom. The factors of an ideal setup include the ability to move material quickly between areas and the ability to move material effectively within each area.

Process Planning for the Maintenance Storeroom

Standardization – Every maintenance storeroom needs to be standardized. In other words, you decide how items will be organized. Is it from left to right or right to left? Top to bottom or bottom to top? Do you place labels above or below? Is this set up the same throughout the storeroom? Is it the same between storerooms?

Visual Management – Providing large visible signage to mark different sections will save time and make the process more efficient. Once a worker has looked up which row and aisle a part is located from the VIN system, markers such as signs and arrows will help guide them to it in the actual storeroom. Labeled maps or diagrams of the floorplan can also be useful designating areas, such as:

$150K
Savings on one project through parts requirement projections
20%
Improvement in productivity and response time to requests
$2 Mil
Annual savings from reducing waste by 30%
100%
On-time completion rate for critical work orders

Spare Parts Management

Maintenance, repair, and operations (MRO) inventory are the supplies used to maintain facilities, plants, manufacturing lines, and more. Organizations can increase productivity, decrease downtime, reduce spending on parts, and boost production. It also allows organizations to easily manage parts inventory across multiple locations. They can track it using FIFO, LIFO, or moving average accounting methods.

The right parts inventory management software handles purchasing and receiving parts, associating parts with assets and PMs, and quickly locating inventory items. It can also integrate with other tools and simplifies tracking. Visibility of spare parts inventory is vital for any organization. Without the proper CMMS system, keeping track of parts and ensuring their availability can be challenging.

Access all parts information in a list view, including location, on-hand amount, unit cost and item number. Attach images to part records for easy identification.
Set up reorder points to track parts you need to order or auto-generate a purchase order when the on-hand amount falls below the threshold.
Relate parts to assets and PMs in order to automatically let technicians know which parts are typically used to repair an asset or perform a PM task.
Use barcodes and QR codes to scan and view part records instantly on a tablet or mobile device. Use parts kitting to issue or return multiple parts with a single item number.
Require work requestors to submit a materials request for approval before a part is charged out of inventory.
