Which trend metrics can I track month over month?

Beyond call-by-call, the dashboard aggregates: missed calls and recovery rate, text response rate, appointments booked and kept, average urgency, first-response time, breakdown by line and language, and the recovered-revenue estimate computed on your declared average job. The curves read by week, month or quarter, and compare period to period. What it changes in practice: you discover Tuesday is your worst day, that 60% of your emergencies arrive after 6 PM, that English comes up more than expected. Business decisions, not just statistics.
