The four numbers to measure first

Every team that starts measuring WhatsApp measures volume first, because volume is the number that is already sitting there. It is also the only number on the list that a rep can improve without helping a single customer.

The four that are worth the trouble

Median first response. How long a customer waits before anyone answers. Not the average, because one abandoned thread drags an average somewhere useless. And not per-rep until you also know how much each rep is carrying.

Waiting right now. A live count, not a report. It is the only number on this page you can act on before lunch, and acting on it is what makes the rest of the measurement credible to the team.

Unique customers engaged. Distinct humans spoken to in the period. Forty messages to one customer is one customer. This is the number that moves when a week was genuinely good.

Conversations gone quiet. Threads past whatever threshold would embarrass you. Set it at the wait you would not want to explain to a customer, not at the one that keeps the list short.

What to do with them

Waiting right now goes on a screen somebody actually looks at each morning. It is the only one of the four you can act on the same day. Median first response, unique customers engaged and conversations gone quiet are a weekly conversation, held with the team rather than about them.

Two warnings. The moment any of these becomes a stick, people optimise the number instead of the customer, and response time is the easiest of the four to game. A fast “let me check and come back to you” stops the clock without helping anyone. Read a few transcripts alongside the numbers and you will see it immediately.

And do not add a fifth this month. The full catalogue has another forty-three, all of them defined; almost none of them are worth watching until you have a specific question that these four cannot answer.
