What's covered

5 topics

  1. 01Core Metrics: AHT, FCR, CSAT

    AHT (Average Handle Time) = (total talk time + hold time + after-call work) ÷ number of calls handled. FCR (First Call Resolution) is the percentage of issues resolved on the first contact with no follow-up needed. CSAT = (positive survey responses ÷ total survey responses) × 100.

  2. 02Net Promoter Score (NPS)

    Measured with a 0–10 'how likely are you to recommend us' survey. NPS = % Promoters (score 9–10) minus % Detractors (score 0–6); scores of 7–8 are 'passives' and are not subtracted or added in the core formula.

  3. 03QA Scorecards

    A QA (quality assurance) scorecard is an internal tool used to evaluate an individual recorded/monitored interaction against defined criteria — greeting, compliance, communication, resolution, and call closing. It's distinct from customer-facing metrics like CSAT or NPS.

  4. 04Hold & Transfer Etiquette

    Always ask permission and briefly explain the reason before placing a customer on hold, give a time estimate, and thank them when you return. For transfers, tell the customer why they're being transferred and, when possible, give the receiving agent a brief summary (a 'warm transfer') so the customer doesn't repeat themselves.

  5. 05Escalation Criteria & De-escalation Steps

    A valid reason to escalate is that the needed resolution is outside the agent's policy authority — not simply that a customer sounds frustrated or a call runs long. To de-escalate an upset customer, listen fully without interrupting, then acknowledge/empathize with their frustration before moving to problem-solving.
