Logistical supply and storage systems and subcontracted complete operations which form part of the production chain, such as the painting of sub-assemblies, should likewise be classified among these modules and sub-systems.
Den logistiske styring af ordreafgivelse og oplagring samt udlicitering af tilknyttede transaktioner, f.eks. maling af komponenter, der udføres på produktionslinjen, regnes ligeledes for et modul eller et undersystem.
