Definition & Explanation

Unlike a Service Level Objective (SLO), which defines a target, a Service Level Indicator (SLI) captures actual, measured performance. It is a concrete, regularly tracked metric used to verify compliance with service agreements and to spot performance gaps early. Common SLIs in logistics include on-time delivery rate (%), average transit time (days), and order error rate. Freight forwarders and contract logistics providers use SLIs to manage process quality and to underpin performance-based billing arrangements with their clients.
