A missing component, container, or feedstock can disrupt production and create a ripple effect across your delivery schedule. Frustrated customers. Delays in getting paid. Damage to your reputation. It’s a headache.
It sounds like an inventory issue, but stockouts are so much bigger than just simple inventory management. Preventing these disruptions doesn’t mean just increasing stock levels. That can tie up capital and increase your inventory carrying cost. With so many manufacturers employing Just-in-Time (JIT) manufacturing strategies, accurate, real-time visibility into what inventory is available, where it is located, and how it is moving is critical to right-sizing your stock levels.
What Causes Stockouts in Manufacturing Operations?
Manufacturing relies on a tightly synchronized process, and an inventory stockout disrupts that.
What are the primary causes of stockouts in manufacturing?
- Forecasting challenges: Demand changes, production schedule shifts, and outdated planning data can cause manufacturers to order too little, order too late, or set safety stock levels too low.
- Supplier delays: Late shipments, partial orders, quality issues, and lead-time variability can leave manufacturers without the materials or components needed to keep production running.
- Inaccurate inventory records: System counts do not match physical inventory because of manual errors, delayed updates, misplaced materials, unrecorded transfers, or incorrect cycle counts.
- Ghost inventory: Inventory appears available in an ERP, WMS, or spreadsheet but is not physically present, usable, or accessible when production needs it.
Often, the data you need is fragmented across multiple systems or suppliers, creating inventory blind spots that make it hard to see what’s really going on…until it’s too late.
The Real Cost of Inventory Shortages
The cost of an inventory stockout often exceeds the value of the missing material. If it stops production, delays a shipment, or forces an expensive schedule change, stockout costs multiply quickly.
Production Downtime
Production downtime costs manufacturers more than $1 trillion every year. In the automotive sector, a single hour of stoppage can cost $2.3 million per hour.
Work stops. Warehouse teams spend time searching for inventory that should have been on hand. Supervisors scramble to re-sequence production lines. It’s a mess all around, and expensive.
Expedited Freight Costs
When a shortage is discovered late, you may need to rush shipments. You pay for expedited freight at premium rates and cut into your margins. And that doesn’t include the labor costs to manage orders and maintain inventory accuracy.
Stockouts also create labor inefficiencies. Teams may spend time verifying counts, contacting suppliers, expediting purchase orders, rearranging production schedules, or manually tracking missing materials.
Customer And Cost-Control Impact
Stockouts also impact your upstream vs. downstream supply chain partners. It can damage relationships and impact customers and suppliers. Without real-time supply chain visibility, costs spiral.
How Manufacturers Can Prevent Stockouts
So, how do you avoid stock risk and reduce supply chain costs? It starts with better visibility. For example, RFID tracking and IoT-enabled inventory validation can provide the real-time inventory accuracy you need. Sensors, tags, gateways, and connected platforms can help teams see what is available, where it is located, and whether it is moving as expected. No more manual cycle counts or assuming the packing list is right.
With the right inventory management systems, you get better visibility across your warehouses, yards, and transportation networks. With this visibility, you can make smarter decisions about inventory management.
Optimize Safety Stock
Safety stock optimization is key to right-sizing your inventory to avoid stockouts. Your inventory position needs to match demand, with a bit extra to account for variability, supplier delays, or uncontrollable disruptions. Too little safety stock? Increased disruption risk. Too much? Increased carrying costs and risk of obsolete inventory.
Optimizing your safety stock requires solid data you can rely on.
Automate Replenishment Triggers
At the same time, reorder points keep your inventory from falling below critical levels. Whether you’re basing automatic replenishment on min-max levels, actual consumption, work-in-progress (WUP) triggers from a Kanban board, or elsewhere, it goes back to accurate inventory data. If your asset management system is weak or counts are wrong, automated replenishment may fail.
Monitor Supplier and Inventory Performance
It’s not enough, however, just to track your in-house inventory; how components move across your supply chain is crucial to avoiding stockouts. Tracking inventory as it moves through your network can help identify potential risks before they turn into shortages.
Essential inventory management KPIs like on-time delivery, fill rates, lead-time variability, order accuracy, and quality issues across suppliers can help you evaluate partners and hold them accountable.
Using Real-Time Visibility to Improve Inventory Decisions
Connected data is the foundation for avoiding inventory stockouts, tracking what is physically available across plants, warehouses, yards, and transportation lanes. IoT, RFID, and automated data collection provide the underlying data you need to manage inventory position and prevent stockouts. With a real-time picture of what’s on-site, inbound, and allocated, you can meet demand.
Surgere’s supply chain visibility solutions offer 99.9% accuracy, integrating with your ERP and other systems to provide a complete, holistic view of your supply chain. Procurement, production, logistics, and warehouse teams can work from the same current data instead of reconciling spreadsheets or reacting after a shortage has already affected operations.
Over time, this visibility helps manufacturers improve service levels, reduce emergency freight, lower excess inventory, and reduce supply chain costs without increasing stockout exposure.
Build a More Resilient Inventory Strategy
When you can validate availability across your supply chain and balance it with demand, you can significantly reduce risk and see potential problems earlier. This visibility is key to production continuity.
Surgere helps prevent stockouts through real-time visibility, giving you the insight you need to understand where inventory is needed, where it should be positioned, and how quickly it can be replenished.
See how Surgere prevents stockouts through real-time visibility with asset management solutions and learn 5 essential inventory management KPIs to monitor to improve inventory decisions and reduce operational risk.
