The work has a span, so the corresponding ability needed to cope with the work span has become an extremely important indicator for the promotion of this rank to the next rank. In this way, the important difference between on-the-job promotion and rank promotion lies in the ability to deal with work span, not the only professional skill. The classification of enterprise architecture can be divided into two parts: business architecture and IT architecture, and most enterprise architecture methods are developed from IT architecture.
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.
②IT 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.
