① Business structure: it is the channel through which the business strategy of an enterprise is transformed into daily operation, which determines the business structure, including business operation mode, process system, organizational structure and geographical distribution.
② IT architecture: The IT framework guiding IT investment and design decision-making is a comprehensive blueprint for establishing enterprise information systems, including data architecture, application architecture and technical architecture.
Compared with RUP and other implementation-oriented laws and regulations, the focus in the field of enterprise architecture is, in principle, the identification, standardization and priority division of internal business requirements, which is also a way to make enterprise information planning. In my opinion, there is a difference between making tool-based products and making enterprise-level products, that is, making enterprise-level products needs to be transformed from a tool-based product company to a consulting service company.
