Why does the TOGAF standard recommend that the Business Architecture be developed first?

While Business Architecture does describe business strategy, its primary purpose in being developed first is to provide prerequisites for other architecture work, not merely to contain the strategy itself.

Mobilizing operations relates more to implementation and ongoing support rather than the initial sequencing of architecture domains in the ADM.

The Business Architecture provides essential information about the organization's strategy, governance, and business processes, which are critical inputs for defining the Data, Application, and Technology Architectures. Without a clear understanding of the business context, architectural decisions in other domains risk not aligning with organizational goals and requirements.

This describes a key output or role of the architecture capability in meeting business goals, rather than the reason for the Business Architecture's specific development order.

Preparation activities and method customization are typically part of the Preliminary Phase, which precedes the detailed development of any architecture domain.
