Conversation Duration: The Clockwork of CX
Conversation Duration: The Clockwork of CX
VitalogyCX dissects “duration”. It dissects it. Because within the flow of seconds and minutes lie signals of friction, failure, and opportunity.
Let’s unpack the anatomy of Conversation Duration and how to measure it with the nuance today’s CX demands.
What Is Conversation Duration?
Conversation Duration measures the total time span of an interaction — but it’s not one monolithic block. It includes several key phases:
graph TD
TD[Total Duration]
TD --> FD[Flow Duration]
TD --> WD[Waiting Duration]
TD --> HD[Handle Duration]
TD --> OD[Outbound Dialing]
WD --> LW[Live Waiting]
WD --> CBW[Callback Waiting]
HD --> CBD[Callback Dialing]
HD --> TKD[Talk Duration]
HD --> WUD[Wrap-Up Duration]
CBD --> ATD[Active Talk]
TKD --> HLD[Hold Duration]
TKD --> INV[Invitee Wait]
1. Total Duration
This is the full time from when the conversation begins (e.g., a customer dials in) until all post-call work is complete. But beware: for many contact centers, especially where agents overlap or transfer, “total duration” often isn’t attributable to a single agent. That’s why it’s critical to segment it.
Breaking Down the Flow
To understand system performance and agent behavior, we track duration in phases. Here’s how it breaks down:
1. Flow Duration
The total end-to-end time the customer is inside your system, regardless of how many agents or steps are involved.
2. Waiting Duration
Only relevant for inbound conversations. It represents the time before an agent picks up. It includes:
- Live Waiting — Time spent in queue, IVR, or ringing.
- Callback Waiting — For scheduled callbacks, time from request to fulfillment.
⚠️ Note: These waiting types often overlap or are non-additive. Don’t sum them blindly.
3. Handle Duration
This is where the agent is actively engaged — or trying to be.
-
Outbound Dialing Duration
The time an agent spends placing an outbound call before it’s answered. -
Callback Dialing Duration
Specific to callbacks — time spent attempting to reach the customer.
Once connected, handle time breaks further into:
→ Talk Duration
Time the customer and agent are in active conversation.
- Active Talk Duration — Real conversation time, excluding holds or transfers.
- Hold Duration — Time the customer is placed on hold.
- Invitee Wait Duration — Time waiting for a second party (like a supervisor) to join.
→ Wrap Up Duration (After Call Work)
Time spent post-call entering notes, tagging, or resolving follow-ups. Often the most overlooked — and the most automatable.
Formula Reference
While no single formula captures all layers of Conversation Duration, here are some foundational ones:
Handle Duration = Outbound Dialing + Callback Dialing + Talk Duration + Wrap Up Duration
Talk Duration = Active Talk Duration + Hold Duration + Invitee Wait Duration
Why It Matters
- Customer Effort: Long wait times or excessive holds show up fast here.
- Agent Efficiency: High wrap-up or outbound dialing times may signal training or tool friction.
- System Friction: Callback wait times or invite delays point to workflow breakdowns.
Most dashboards show total handle time. Few reveal the why behind it. VitalogyCX does — by separating duration into its vital parts.
Use with Care
Duration metrics are easy to misinterpret in isolation:
- A short talk time may indicate resolution or rushed service.
- A long wrap-up may mean diligence or tool inefficiency.
- A long wait may be systemic or just peak load.
Context is the compass. Layer these metrics with customer intent, agent behavior, and conversation outcomes.
