> A deviation, in logistics and supply chain management, is any measurable gap between planned or contractually agreed performance and actual results.

A deviation, in logistics and supply chain management, is any measurable gap between planned or contractually agreed performance and actual results. It surfaces across delivery schedules (delays), quantities (over- or under-shipments), quality (damage, defects), and routing (unplanned changes to the transport path). What matters most is not the occurrence itself but the response: deviations must be documented, assessed for root cause and business impact, and addressed through corrective or preventive action. Systematic deviation tracking also feeds supplier scorecards and continuous improvement programmes.
