Modeling

Intro

Modeling is the construction of models for a domain using appropriate methods and notations. In EA, it structures knowledge for analysis, design, and change.

Key points:

• Provides repeatable ways to capture enterprise views.
• Supports traceability from strategy to solutions.
• Common use cases across EA/BPM/Data/App/Tech include process modeling, data modeling, capability mapping, and integration design.
• Pitfall: mixing notations or levels, causing confusion.

Examples:

• Using BPMN for operational workflows.
• Creating ER models for core data entities.
• Modeling application interactions to plan integrations.

In practice:

Select standard notations, define modeling conventions, and govern updates to keep models useful.
