International supply chain reference model (ISCRM)

The International Supply Chain Reference model (ISCRM) describes the processes, parties and documents exchanged in the conduct of international trade. More detailed work with the same scope was developed later and is called the Buy-Ship-Pay Model.

ISCRM was created within UN/CEFACT and is described in the document “InternationalSupplyChainReference Model2003.doc“. The Use-Case diagram below shows the major processes involved. Each Use-Case is further detailed in the model and document. The Establish Business Agreement Use- Case describes the processes involved in establishing a contract. The Ship Use-Case describes the processes involved in preparation for the movement of goods, transportation and the export and import processes. The Pay Use-Case describes the processes involved in letter of credit payments.

The International supply chain reference model and the Buy-Ship-Pay Model have the same origin. The idea to create reference models for trade processes was refined to the more specific scope of buy, ship and payment processes within the supply chain.

The concept is described in “ISCM Reference Model-2001” available at https://unece.org/fileadmin/DAM/uncefact/BRS/BRS_SCRDM_v1.0.0.2.pdf
