Storage and transportation loss ratio

Storage and transportation loss ratio measures losses during warehousing and movement relative to the amount handled.

Storage and transportation loss ratio is a logistics and operations KPI that compares the amount of material, product, or inventory lost during storage and transport with the total amount handled over a defined period.

In manufacturing, the loss may include damage, spoilage, leakage, shrinkage, missing inventory, or other unplanned losses that occur in warehouses, staging areas, internal logistics, or external transportation. The ratio is commonly calculated using quantity, weight, units, or value, depending on the material and reporting purpose.

This KPI can help indicate problems in material handling, packaging, warehouse control, transport conditions, or inventory transaction discipline. It should not be treated as a direct measure of inventory accuracy. Inventory accuracy depends on whether system records match physical inventory, while this ratio focuses on losses associated with storing and moving goods.

In ISO 22400-related manufacturing KPI discussions, storage and transportation loss ratio is typically viewed as a supporting logistics indicator rather than a complete inventory control metric.

Tiered suppliers align with OEM onboarding expectations by translating customer flowdowns into controlled internal processes, evidence requirements, data exchanges, and change controls. This is not just portal access or a checklist exercise; success depends on process maturity, system integration, and traceable execution.

What does AS9100 require for counterfeit parts prevention?

AS9100 requires controlled processes to prevent counterfeit or suspect counterfeit parts from entering or being used in the product. It does not prescribe one tool or guarantee detection. The practical controls depend on sourcing risk, product criticality, customer flowdowns, traceability maturity, and system integration.

How can OEMs gain visibility into Tier-2 and Tier-3 aerospace suppliers?

OEMs can improve Tier-2 and Tier-3 visibility, but usually not by forcing full-stack replacement across the supply base. In aerospace, practical visibility comes from phased data sharing, supplier portals, milestone reporting, traceability requirements, and targeted integration around critical parts, quality events, and constrained capacity. Results depend on supplier participation, data quality, governance, and validation.

What KPIs should be on an aerospace supplier scorecard?

An aerospace supplier scorecard should not be built around on-time delivery alone. It should balance delivery, quality, responsiveness, traceability, and risk signals, with definitions tight enough to survive audit scrutiny and system handoffs. The right KPI set depends on part criticality, process maturity, data quality, and how well ERP, MES, QMS, and supplier workflows are integrated.
