A capability represents an ability that an active structure element, such as an organization, person, or system, possesses.
In the field of business, strategic thinking and planning delivers strategies and high-level goals that are often not directly implementable in the architecture of an organization. These long-term or generic plans need to be specified and made actionable in a way that both business leaders and Enterprise Architects can relate to, and at a relatively high abstraction level.
Capabilities help to reduce this gap by focusing on business outcomes. On the one hand, they provide a high-level view of the current and desired abilities of an organization, in relation to its strategy and its environment. On the other hand, they are realized by various elements (people, processes, systems, and so on) that can be described, designed, and implemented using Enterprise Architecture approaches. Capabilities may also have serving relationships; for example, to denote that one capability contributes to another.
Capabilities are expressed in general and high-level terms and are typically realized by a combination of organization, people, processes, information, and technology. For example, marketing, customer contact, or outbound telemarketing
