Integration Architecturearchitecture is the decomposition of the very large information system into manageable components and the decoupling of the components by managed interfaces with formal syntax and precise semantics. The managed interfaces are enriched by non-functional properties and thus form services which are govIsolate 发表于 2025-3-23 16:53:06
Infrastructured evolution: Most important is the decoupling of the applications from infrastructure. Infrastructure standardization and lifecycle management allow applications to be quickly developed and to follow their own lifecycles, only loosely coupled to infrastructure lifecycles.

Business-IT AlignmentA classical, that is a hierarchical and departmental, setup with its corresponding governance model and budget authority is not well suited to managed evolution. A new governance model, the domain-based model, is introduced and is shown to work best for managed evolution. The roles and processes forAggrandize 发表于 2025-3-23 23:05:49

Agility as measured by the time to market and the cost to market for a given amount of functionality serves as a good strategic indicator to steer managed evolution.
