Changes to the voice layer affect revenue and customer experience. A disciplined framework reduces risk by classifying work, proving impact, and sequencing actions. Each request moves through intake, risk scoring, approval, and scheduled execution with tested rollback. Success is validated with pre and post-metrics, not just ticket closure. 


 

Change classes: 

• Standard, minor, major, and emergency with approval paths 

Execution: 

• Impact analysis, stakeholder comms, MOPs, and rollbacks 
• Maintenance windows by site and business hours 
• Validation steps and back-out triggers

Metrics: 

• Change success rate and volume by type 
• Incidents linked to change and mean time to restore 
• Time from request to completion for common MACD 

Result: faster iteration with fewer surprises, and an auditable trail that stands up to internal and external reviews.
