Quality reviews · Customer service, orders & after-sales

Stop scoring random conversations. Score the ones that went wrong.

In one minute: why random reviews miss the conversations that matter, and how to find four times more.

Read the transcript1 min read

Every month, your team handles thousands of conversations. Somewhere in there, a few hundred went wrong.

Your team leaders review a hundred of them, picked at random. Like most companies: sixty-three percent do.

Nine land on a problem. The rest, the wrong answers, the broken promises, nobody ever sees.

But conversations that go wrong leave traces. A low score. A reopened ticket. A transfer. A customer who comes back.

Bring them into one place, and let them choose. Sixty percent on signals, twenty on what's new, twenty still at random, so everyone stays in view.

Same hundred reviews. Forty problems found, instead of nine.

I'd be glad to look at your reviews with you. Let's set up thirty minutes to talk it through — pick the time that suits you.

Why random sampling misses

Random QA sampling finds problems at the rate they happen. That’s the problem.

Random sampling9

problem conversations found in 100 random reviews.

When just under 10 % of conversations go wrong, a random pick lands on one about once in ten. The rest of your review hours go to conversations that were fine.

Signal-led sampling40

problem conversations found in the same 100 reviews.

Most reviews go first to what your tools already flagged — low CSAT, reopened tickets, escalations, long handle times, negative sentiment. A small random share stays, so you still see the baseline.

Illustrative month, as in the video and the simulator: thousands of conversations, a few hundred that went wrong, 100 reviews split 60 % on signals, 20 % on what’s new, 20 % at random. Run the simulator to use your own numbers.

What you leave the call with

Three things you can run next month — with or without us.

  1. 01

    Your current picking method, mapped

    How your team chooses which conversations to review today, and which kinds of problem that method can never reach.

  2. 02

    Your alert signals, ranked

    The signals your helpdesk, CRM and phone system already hold — low CSAT, reopened tickets, escalations, long handle times — and the one or two worth connecting first.

  3. 03

    A three-basket plan and scoring grid

    How to split next month’s reviews between flagged conversations, what’s new and a random control share, plus the grid to score them consistently.

Before you book

Fair questions.

What is a QA sampling plan?

A rule for choosing which customer conversations your quality team reviews each month. Instead of a purely random pick, it mixes conversations flagged by alert signals, what’s new (agents, products, processes) and a small random control share.

Which alert signals should decide what QA reviews?

Start with the ones your tools already record: low CSAT or NPS answers, reopened tickets, escalations, unusually long handle times and negative sentiment. Pick the two you trust most, then add more.

Do we need a new QA tool?

No. We start from the data your helpdesk, CRM or phone system already holds. If a useful signal is missing, we tell you which one and why.

We only review a few dozen conversations a month. Is it worth it?

Yes. The smaller your sample, the more each review has to count — that’s exactly where aiming beats random.

Is this a sales call?

It’s a working session. You leave with a plan you can run on your own. If you want help putting it in place, we can talk about that separately.
