• Licenses as needed
• Usage monitoring
• ROI measurement

Usage-Based:

• Track API calls
• Budgets per team
• Alerts on overages

Metrics and KPIs

Adoption

• Active users/licenses
• Frequency of use
• Feature utilization

Productivity

• Code velocity
• PR cycle time
• Bug rate

Quality

• Agent output acceptance
• Revision rate after generation
• Security findings

Organizational Integration

Center of Excellence

Tasks:

• Develop best practices
• Conduct training
• Foster community
• Drive innovation

Support Structure

• L1: Self-service docs
