In the absence of existing Architecture Descriptions, the development of a Business Architecture would begin with the gathering of relevant information about the business. This information can come from strategic documents, business plans, process documents, and stakeholder interviews, among other sources. Once gathered, this information would be used to create Business Architecture models that articulate the business vision, strategy, governance, organization, and key business processes. These models provide a blueprint that captures the essence of the business and guides subsequent architecture work.
