Return to Part 1 Requirements

Traceability SHALL support impact analysis across conceptual, logical, implementation, deployment, and Evidence layers.

Part 1, Section 13.7: Traceability Requirements.

Impact analysis depends on traceability across architectural layers. A change to a conceptual concern may affect logical elements, implementation artifacts, deployment artifacts, and evidence. A change to evidence, deployment, implementation, or logical material may also affect the interpretation of architectural support.

This requirement supports change control, review, governance, and risk management across the architecture lifecycle.

This requirement applies to traceability relationships used for impact analysis.

It applies specifically to impact analysis across:

• Conceptual layers
• Logical layers
• Implementation layers
• Deployment layers
• Evidence layers

Verification SHALL confirm that Traceability supports impact analysis across conceptual, logical, implementation, deployment, and Evidence layers.

Verification activities include review checks confirming that:

• Traceability identifies affected upstream elements
• Traceability identifies affected downstream elements
• Impact analysis spans the required architectural layers
• Impact analysis distinguishes one-to-one, one-to-many, many-to-one, and many-to-many relationships where applicable
