According to the ArchiMate 3.2 Specification1, the ArchiMate core language defines a structure of generic elements and their relationships, which can be specialized in different layers. Three layers are defined within the ArchiMate core language as follows:

The Business Layer depicts business services offered to customers, which are realized in the organization by business processes performed by business actors and roles.

The Application Layer depicts application services that support the business, and the applications that realize them.

The Technology Layer comprises both information and operational technology. You can model, for example, processing, storage, and communication technology in support of the application world and Business Layers, and model operational or physical technology with facilities, physical equipment, materials, and distribution networks.

Comprehensive and Detailed in Depth Explanation:TheGroupingelement is acomposite elementin ArchiMate. Itcombines multiple elements into a single logical unitto simplify the representation of complex architectures.

UnlikeAggregation, which represents a relationship between a whole and its parts,Groupingallows the modeler to create arbitrary clusters of elements, regardless of their layer or type.

TheArchiMate 3.2 Specificationconfirms thatGroupingis a composite element used for structuring models and can include elements from different aspects and layers.

The diagram uses the ArchiMate notation for physical elements, which are used to model physical concepts like machines, physical installations, materials, and distribution networks. A is an equipment element, which represents a physical machine, tool, or instrument that can create, use, store, move, or transform materials. B is a material element, which represents tangible physical matter or energy. C is a distribution network element, which represents a physical network used to transport materials or energy.
