Model

Intro

A model is a simplified or abstract representation of a subject area. In EA, models help stakeholders understand, analyze, and communicate structure and behavior.

Key points:

• Reduces complexity to focus on key elements.
• Improves alignment and decision making.
• Common use cases across EA/BPM/Data/App/Tech include capability maps, process models, data models, and integration diagrams.
• Pitfall: over‑modeling detail that obscures purpose.

Examples:

• Capability model to guide investment planning.
• BPMN process model for onboarding.
• Logical data model for the customer domain.

In practice:

Define the audience and purpose first; choose notations and scope to meet that need.
