Based on the ArchiMate 3 documents or objectives, an application interface represents a point of access where an application service is made available to a user, another application component, or a node. An application interface specifies how the functionality of a component can be accessed by other elements. The notation for an application interface is a square with a small circle attached to it.

According to the ArchiMate language structure, a concept is either an element or a relationship. An element is either a behavior element, a structure element, a motivation element, or a composite element. A and B in the diagram correspond to these concepts respectively.

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.

According to the physical elements metamodel, a facility is a specialization of a node, which is an active structure element that represents a computational or physical resource that hosts, manipulates, or interacts with other computational or physical resources. A facility can be used to model physical buildings or locations.

The diagram uses the ArchiMate notation for a goal element and an aggregation relationship. A goal element represents an end state that a stakeholder intends to achieve. An aggregation relationship indicates that a whole is composed of parts. In this case, the goal 'Reduce Expense Ratio from 13% to 11%' is composed of three sub-goals that contribute to its achievement.
