Repository

Intro

A repository is a managed storage location for enterprise information. In EA, it holds strategies, structures, models, and designs to enable traceability and reuse.

Key points:

• Centralizes artifacts for governance and collaboration.
• Improves consistency, versioning, and auditability.
• Common use cases across EA/BPM/Data/App/Tech include process models, application and technology designs, and reference data.
• Pitfall: unmanaged repositories that become outdated or fragmented.

Examples:

• Architecture repository storing capability maps and roadmaps.
• Model repository with BPMN processes and data models.
• Design repository for application interfaces and deployments.

In practice:

Define ownership, metadata, and lifecycle controls to keep repository content accurate and useful.
