How many open orders are too many? Critical thresholds in complex supply chains

In complex supply chains, open orders can turn into bottlenecks if they are not monitored in time. But how do you know when a number of open orders is about to cross the red line? In this article we help you define critical supply chain thresholds, that is, the points where you can make decisions before the domino effect begins: delays, complaints, cost overruns or missed deliveries.

Why thresholds are not just "a number"

In distributed chains, the apparent number of open orders can vary by seasonality, product type or logistics variants.
Every operation has an operational capacity: the number of orders you can process per day, week or month. Thresholds serve as an early warning, not as a routine.

Key metrics to get started

To set actionable thresholds, we recommend measuring:

• Average lead time and its deviation.
• Open orders vs. real processing capacity.
• Backorder growth rate.
• Service level (OTD – On-Time Delivery).
• Traceability of origin: how many orders are held up by external suppliers or internally.

Defining critical thresholds

Threshold 1: soft signal. When the number of open orders exceeds 80% of your operational capacity, it is time to analyze why.

Threshold 2: medium alert. Reaching 100% of capacity means that, without action, delays are imminent.

Threshold 3: critical. Once you go past 110–120%, you enter the risk zone: impact on OTD, stock discrepancies, operational risks and financial risks.

How to monitor and act

We suggest this step-by-step to keep your thresholds under control:

First, measure lead time and backlog daily. Use a control panel, whether in Excel or an automated dashboard.

Second, compare the backlog with your average operational capacity. If there are gaps, trigger automatic alerts by email or SMS to avoid surprises.

Third, identify variations by SKU or by customer type. The bottleneck is often concentrated in a single category.

Fourth, activate a contingency plan if you see the critical threshold approaching: you can add extra shifts, reallocate stock or communicate possible delays.

And fifth, review your thresholds every month. Adjust them according to seasonal changes or variations in your operational structure.

Advantages of working with thresholds

• Proactivity: you detect delays before they impact OTD.
• Visibility: you know where the bottlenecks are coming from.
• Flexibility: you can adjust resources without panicking.
• Objective decision-making: you compare against your real capacity.
