Call handle time bell curve
This bell curve shows a simplified distribution of support-call handle times centered on eight minutes. It can help a manager describe what is typical and identify a small number of calls that deserve review at either end of the range. Handle time alone is not a quality score: a short call may be unresolved, and a longer one may reflect a difficult but successful case. Segment by call type, channel and shift before drawing conclusions. The curve is most useful alongside measures such as resolution, customer satisfaction and repeat contact. It gives teams a concrete starting point for reviewing assumptions, data quality and next steps together.

Scenario
A support manager reviews a stable queue's call duration.
Key decisions
- Define the cohort: Compare similar call types and shifts.
- Find the center: Identify typical handle time.
- Investigate tails: Review unusually short or long calls.
When to reuse this
Use for continuous operational measures after separating distinct call types.
