Call center operators often make 7 mistakes: lack of people during peak hours, not measuring KPIs, confusing IVR causing customers to get stuck, no fallback when overloaded, taking poor notes, not coaching from recordings, and forgetting messaging channels. Each error has signs and how to fix it. Zenify recorded 74% of customers switching channels when service was poor.
TL;DR
- Shortage of people during peak hours → schedule according to data.
- Not measuring KPI → running "groping".
- IVR is messed up → customer gets stuck in menu, cancels call.
- No fallback → call "hangs".
- Forgot message channel → customer falls on Zalo/Messenger.
Error 1: Lack of people during rush hour
Signs: During peak hours, customers waited for a long time, many missed calls; now there are no staff members "sitting around".
How to fix: Measure call volume by hour 4-8 weeks → schedule on peak, off-peak shifts (see Workforce management).
Mistake 2: Not measuring KPIs
Signs: don't know how many matches to miss, how long to hold, which staff is weak.
How to fix: Daily report: number of calls, missed calls, hold time, CSAT. Without data, it is impossible to manage (see KPI call center).
Error 3: IVR is messed up, customer menu is stuck
Signs: Customers click multiple floors to reach you; Cancel call at menu.
How to fix: menu ≤4 options, ≤2 floors, always has "meet real people" button (see What is IVR).
Error 4: No fallback when overloaded
Signs: the call is "hanging" silently, the customer cancels because no one listens.
How to fix: Configure to transfer management mobile, leave a message, or transfer to another branch/team when overloaded (see Hold time).
Mistake 5: Taking poor notes
Signs: The operator does not record the call content; The customer calls back and has to start from the beginning.
How to fix: Require notes + save guest profile; Taking notes is a QA criterion (see QA score).
Mistake 6: Not coaching from recording
Signs: Score the recording for yes or no coaching sessions; Staff keeps repeating mistakes.
How to fix: Score each employee equally, coach with specific examples, measure again after 2 weeks (see Quality monitoring).
Error 7: Forgetting the messaging channel
Signs: Customers text Zalo/Messenger but no one responds; Customer complains "no response to message".
How to fix: Merge messaging channels into the same system, measure messaging FRT, assign person in charge (see Multi-channel Helpdesk).
