Boundaryless Information Flow

Intro

Boundaryless Information Flow describes an environment where information is readily accessible and shared across systems and organisations with appropriate security. In EA, it aims to reduce silos and improve interoperability.

Key points:

• Promotes standard interfaces and shared data models
• Improves collaboration and end‑to‑end processes
• Common use cases: cross‑domain data sharing, platform integration, partner connectivity, API ecosystems, analytics
• Pitfall: ignoring security and governance can create compliance risks

Examples:

• Shared customer data domain accessed by multiple capabilities
• API gateway enabling secure partner integrations
• Event streaming connecting applications across domains

In practice:

See Enterprise Architecture for operating models that support interoperability.
