Enter response or handling durations to get average response time, resolution rate and distribution, supporting support-team efficiency reviews, staffing and process tuning.
把客服首響(或平均響應)時長逐條錄入,計算平均響應時間、中位數與達標率,並給出最長/最短響應,用於服務 SLA 達成情況復盤;資料僅在瀏覽器本地處理,不上傳。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Average response time | ART = Σ(first-response time) ÷ ticket count; count business hours only | Customer-service KPI practice |
| MTTR concept | MTTR = Σ(repair time) ÷ incident count; tracked separately from first response | ITIL 4 Incident Management practice |
| Resolution rate | Resolution rate = on-time-resolved ÷ total × 100%; common SLA: first response ≤1 h, fix ≤24 h | Common SLA convention |
| Measurement caveats | Fix whether auto-replies count as first response and how cross-day tickets are dated; document the rules | Metric definition governance practice |
