The LPI provides not only a comprehensive assessment of logistics performance worldwide, but
also an analysis of performance trends which makes it possible to understand trends over time.
Performance is evaluated using a 5-point scale and the overall LPI is aggregated as a weighted average
of the six areas of logistics performance. The LPI also includes a set of domestic performance
indicators which is not included in the overall country score. It is also complemented with quantitative
information on particular aspects of international supply chains in respondents' countries of work,
including import/export, lead time, supply chain costs, customs clearance, and the percentage of
shipments subjected to physical inspection
