Risk Assessment Tiering

Risk assessment tiering evaluates design risk to determine the appropriate documentation depth. It assigns Tier 1, 2, or 3 based on logic complexity, resource constraints, and side effects to reduce ambiguity and guide verification planning.

To determine the documentation tier, identify primary risk factors like logic complexity and potential side effects during a design review. Map these risks to the structured criteria to assign Tier 1, Tier 2, or Tier 3.

You need to produce invariants and verification artifacts when your design risk assessment assigns a Tier 3 Verification level. This tier enforces structural decomposition and artifact generation to prevent design misinterpretation.

The best way to structure design documentation is applying a tiered risk assessment. Map logic complexity and resource constraints to defined tiers, ensuring you generate the required invariants and decomposition artifacts for higher risk tiers.

Risk-based tiering works for basic design changes by assigning them to Tier 1. This level requires minimal documentation depth, allowing you to efficiently process low-risk changes without generating unnecessary structural verification artifacts.
