An Enterprise Architecture (EA) Capability is the organizational function responsible for effectively carrying out architectural activities. It is defined by the combination of structures, roles, responsibilities, skills, and processes that an organization puts in place. This capability enables the enterprise to establish, maintain, and leverage its architecture. The question directly describes the constituent elements that form the definition of an EA Capability as outlined in the TOGAF standard.

B. An Enterprise Architecture: This is the output or result of the architectural activity, not the organizational function or ability that creates and manages it.

C. An EA framework: This is a structured set of methods, tools, and processes (like TOGAF) used by the EA Capability to develop an Enterprise Architecture.

D. An EA repository: This is a tool or system used by the EA Capability to store, manage, and analyze architectural artifacts and information.

Part VI

Section 44.1

Establishing an Architecture Capability: "In order to carry out architectural activity effectively

it is necessary to put in place an appropriate organization

processes

roles

responsibilities

and skills to create an Architecture Capability." This statement directly aligns with the question's phrasing.

Part I

Section 3.41

Definitions: Defines Enterprise Architecture Capability as "The organization

processes

skills

and roles required to establish and operate an architecture function."

Section 2

What is an Enterprise Architecture Capability?: This guide explains that an EA Capability is the "combination of people

process

and information that is required to deliver architecture." This reinforces that the capability is the sum of these organizational parts.
