Quick Answer (TL;DR)
First Response Time measures time to first support response. The formula is Median time from ticket creation to first response. Industry benchmarks: <1 hour for high-priority. Track this metric when evaluating support quality.
What Is First Response Time?
Time to first support response. This is one of the core metrics in the operational metrics category and is essential for any product team serious about data-driven decision making.
First Response Time measures the health and efficiency of your product infrastructure and team operations. While not a customer-facing metric, it directly impacts user experience and your team's ability to ship improvements.
Understanding first response time in context --- alongside related metrics --- gives you a more complete picture than tracking it in isolation. Use it as part of a balanced metrics dashboard.
The Formula
Median time from ticket creation to first response
How to Calculate It
Apply the formula Median time from ticket creation to first response using data from a consistent time period. Pull the values from your analytics platform or data warehouse, compute the result, and compare against the benchmarks below.
Benchmarks
<1 hour for high-priority
Benchmarks vary significantly by industry, company stage, business model, and customer segment. Use these ranges as starting points and calibrate to your own historical data over 2-3 quarters. Your trend matters more than any absolute number --- consistent improvement is the goal.
When to Track First Response Time
When evaluating support quality. Specifically, prioritize this metric when:
You are building or reviewing your metrics dashboard and need operational indicators
Leadership or investors ask about operational performance
You suspect a change in product, pricing, or go-to-market strategy has affected this area
You are running experiments that could impact first response time
You need a quantitative baseline before making a strategic decision
How to Improve
Automate monitoring and alerting. Do not rely on manual checks. Set up automated alerts that trigger when this metric crosses a threshold so your team can respond immediately.
Invest in infrastructure and tooling. Operational metrics improve when you invest in better CI/CD pipelines, monitoring tools, and incident response processes.
Set clear SLAs and track compliance. Define service-level agreements for this metric and hold teams accountable. What gets measured and targeted gets improved.
Common Pitfalls
Using averages instead of medians. Time-based metrics are often skewed by outliers. A few extremely slow cases can inflate the average and mask the typical experience. Use medians for a more accurate picture.
Setting thresholds too tightly or loosely. Overly sensitive alerts cause alarm fatigue while loose thresholds miss real issues. Calibrate against historical baselines and adjust as the system matures.
Measuring without acting. Tracking this metric is only valuable if you have a process for reviewing it regularly and a playbook for responding when it moves outside acceptable ranges.
