Why are your orders shipping late?

An Order Fulfillment Optimization Playbook decomposes fill rate failures into inventory-driven, logistics-driven, and demand-driven causes, so the right fix lands against the right cause.

The Challenge

Fill rate is a single number hiding three different stories

  • One metric, three failure modes

    Most fulfillment dashboards report fill rate as a single percentage. But every fill rate gap has a cause: inventory was missing, logistics was late, or demand outran the forecast. Without separating the three, every team gets the same generic action: "improve fill rate". Nobody knows what to actually change.

  • Customer impact is uneven

    A 3% fill rate gap on commodity SKUs is a different problem from a 3% gap on strategic accounts. Most teams chase the headline number instead of triaging by customer impact, which means high-margin or high-strategic-value accounts get the same response as the long tail.

  • Fixes solve last quarter, not next quarter

    Root cause reviews happen after the quarter closes. The fixes that emerge address the failure that already happened. By the time they land, the failure pattern has shifted to a different cause, and the team is solving the wrong problem.

How eyko Solves It

Separate the three causes, prioritize by customer impact

An Order Fulfillment Optimization Playbook joins order, inventory, logistics, and demand data. It decomposes every fill rate gap into inventory, logistics, or demand cause, weighs the gap by customer impact, and recommends the fix that moves the most fill rate per unit of effort.

Fill Rate Gap by Root Cause | What
Executive Summary

Fill rate sits at 91.3% against a 95% target. 42% of the shortfall is inventory-driven (safety stock gaps on 20 SKUs). 31% is logistics-driven (carrier delays concentrated on Southeast lanes). 27% is demand-driven (forecast misses on 8 SKUs). Restoring safety stock on the top 20 items projects fill rate to 94.2%, closing most of the gap with a single action.

Frequently asked questions

Everything you need to know about Fill Rate Gap by Root Cause.

Order Fulfillment Optimization is an AI-driven analysis of fill rate failures that decomposes every missed or late shipment into inventory-driven, logistics-driven, or demand-driven cause. The output ranks the gaps by customer impact and recommends the specific operational fix that closes each one. The headline is the cause mix, not a single fill rate number.

The Playbook reads from your order management system (orders, fulfillment events, ship dates), warehouse management system (inventory positions, pick events), TMS (carrier routing, on-time performance), and demand planning (forecast versus actual at the SKU level). It also pulls customer hierarchy from the CRM so customer impact can be weighted properly.

For every missed or late shipment, the Playbook traces back the chain: was inventory available at the time of order? Was the carrier on time on that lane? Was demand above forecast for the SKU? The first failing condition becomes the primary cause. The output aggregates these traces across the analysis window to surface the cause mix and rank the fixes by total fill rate impact.

Yes. The Playbook weights each fill rate gap by the customer it affected: strategic accounts, high-margin accounts, and at-risk renewals are weighted higher than commodity orders. The output recommends fixes in the order that maximizes weighted fill rate, not just unweighted fill rate, so operational effort lands where it protects the most revenue and the most relationship value.
