Overview

Evidence ensures that operational safeguards are documented before a change is implemented.

These safeguards reduce the impact of failures and enable rapid recovery.

Types of Evidence

Typical evidence includes:

Describes how the change can be reversed if issues occur.

Example:

• revert configuration
• restore previous pricing
• disable new routing rules

Describe how the change was validated before release.

Examples:

• billing simulations
• pricing validation tests
• data integrity checks

Describes how the system will detect problems after deployment.

Examples:

• revenue anomaly alerts
• payment failure monitoring
• billing reconciliation checks

Ensures revenue reporting remains correct.

Examples:

• sample invoice verification
• accounting reconciliation
• reporting validation

Organizations may configure required evidence types based on:

• change type
• system
• domain

Changes cannot be submitted until all required evidence is provided.

Operational failures often occur when safeguards are missing.

Evidence ensures that teams have:

• tested the change
• planned recovery procedures
• validated revenue impact
