No two cool chains are alike. Nevertheless, a management system assessing PTSP logistics performance and aiming to allow for comparability between companies must identify and rely on the fundamental elements of a logistics chain. These fundamental elements are found by splitting a real cool chain into operations so that each operation can be made comparable with a similar operation of a different real cool chain.

The qualification process for each operation undergoes an assessment in two parts: The Part “Cool Chain Quality Conformance” (CCQC) checks for conformity of the company with basic requirements for a high-quality cool chain. The Part “Cool Chain Quality Indicator” (CCQI) assesses the quality of an operation quantitatively and relates the resulting CCQI points for an operation to the CCA benchmark.
The benchmarking process is executed with the help of CCQI master tables that list relevant risk control measures (RCM) and their assigned effectiveness for each operation to assure the quality of the cool chain.
