Summary/Abstract: A survey using six Likert items was used to obtain six components of Logistics Performance Index (LPI). Each component was rated by respondents on a scale of 1–5. The LPI reports use a single item to measure a complex construct and do not indicate reliability of the entire scale or an item/question. Most of the existing methods for verifying the reliability of Likert scales with different sets of assumptions violate one or more features of such scales.
