The role class “Enterprise” should be used for business structures. The definition of an “Enterprise” is given in IEC 62264-1:2013, 5.3.2: “An enterprise is a collection of sites and areas and represents the top level of a role based equipment hierarchy. The enterprise is responsible for determining what products will be manufactured, at which sites they will be manufactured, and in general how they will be manufactured. Level 4 functions are generally concerned with the enterprise and site levels. However, enterprise planning and scheduling may involve areas, work centers, or work units within an area.”
