leveringsdiff

Leveringsdiff is a term used in logistics to describe the difference between the promised delivery time for an order and the actual delivery time that is achieved. It is typically expressed in days or hours and can apply to individual orders, shipments, or customer groups. The leveringsdiff is calculated as actual_delivery_time minus promised_delivery_time. A positive value indicates a late delivery, a negative value indicates that delivery occurred earlier than promised, and zero indicates on-time delivery.

In practice, leveringsdiff serves as a performance indicator for suppliers, logistics providers, and distributors. It can be used to monitor service levels, trigger customer service follow-ups, and support SLA management. Companies may aggregate leveringsdiff across orders to compute average delivery delta, distribution of deltas, and percent on time. It is often used alongside related metrics such as on-time delivery rate and total lead time to assess reliability and responsiveness.

Measurement considerations: ensure consistent timestamps for order placement, dispatch, and delivery; account for time zones and business hours; decide whether to measure from order confirmation, production completion, or shipment readiness to delivery, and whether to treat partial deliveries or multi-stop routes as separate deltas. Data quality and granularity matter for meaningful interpretation.

Example: If an order was promised for April 10 but delivered on April 13, leveringsdiff is 3 days. If it arrived on April 9, leveringsdiff is -1 day.
