According to TOGAF, who usually initiates a Request for Architecture Work?

The architecture organization is the recipient of the Request for Architecture Work and is responsible for responding to it, rather than initiating it for external stakeholders.

While the CIO/CTO may be involved in or endorse the need for architecture, the Request for Architecture Work originates from the business unit or program with the actual business problem, which is referred to as the sponsoring organization.

The corporate governance board provides strategic oversight, but they typically delegate the initiation of specific architecture work to a sponsoring organization with a direct business need.

Senior management might represent the sponsoring organization, but 'sponsoring organization' is a more precise term in TOGAF for the entity driving the request.

According to TOGAF, the Request for Architecture Work is a formal request for architectural services, usually issued by the sponsoring organization or business domain that identifies a need for architecture development to support a specific business requirement or project. This organization provides the context and justification for the architecture work.
