What it is (plain English)
Enterprise Architecture models business applications and their relationships to capabilities, processes, information, and technology, then supports assessment, rationalization, visualization, roadmaps, and data certification.
Problems it solves
- Application portfolios are evaluated without shared capability or technology context.
- Rationalization decisions lack current ownership, lifecycle, cost, and risk data.
- Architecture plans are disconnected from strategy and execution.
What must exist first
Define the business-application model, ownership, and the capabilities or architecture domains in scope. EA uses Business Application records in the platform CMDB model.
What the customer needs to provide
- Business applications and owners.
- Capabilities, processes, information, and technology relationships as applicable.
- Assessment and lifecycle criteria.
- Architecture governance and publication decisions.
Where it can go next
Architecture Analyzer, roadmaps, application rationalization, information and technology portfolios, and strategic-planning alignment can be introduced according to scope.
