Summary
The 1:1 WhatsApp enquiry loop was measured end to end, webhook to send, on the live channel. The transport is not the bottleneck; the time goes to knowledge-base coverage and model re-asks.
The loop is measured
The 1:1 WhatsApp enquiry loop — a customer’s message arriving on the rep’s business number, the agent composing a cited answer, and the reply going out — has been measured end to end: webhook to send, on the live channel.
Where the time goes
The transport is not the bottleneck. The slow terms are:
- Knowledge coverage — questions the product knowledge base cannot yet answer confidently.
- Model re-asks — the agent asking again rather than guessing.
Those are the two levers that move a real conversation, and they are where we are investing next.
Why it matters
A measured loop means the team argues about the right things. The next gains come from widening knowledge coverage and tightening the answering prompt — not from plumbing. That is where a customer-service product should want its bottlenecks to live.
