# What changes when *every call is evaluated?*

A sample tells you about the calls you picked. Full coverage gives your team more conversations to learn from, more evidence for coaching and a way to spot problems that keep coming back.

Coverage and independent research

## Coverage in numbers.

Coverage calculation

**50×**

#### as many calls in scope

A 100% automated pass covers 50 times the calls in a 2% human sample.

100% ÷ 2% sample; coverage, not accuracy

Coverage calculation

**98%**

#### of calls outside your human sample

With a 2% sample, 98% of recorded calls receive no human QA review. A full automated pass brings them into scope.

100% − 2% human sample

Independent research

**100%**

#### recommended QA coverage

Independent research recommends evaluating every interaction to guide coaching and recognition.

[ContactBabel · AI for Workforce Engagement ↗](https://www.contactbabel.com/ai-for-workforce-engagement/)

At a 2% human sample, 98% of recordings sit outside manual QA. The 50× comparison is arithmetic. The research recommendation supports broader review; it does not measure Call1 results.

From findings to action

## What your team can do with more calls.

01

### Coach from recurring patterns.

One poor call may be an exception. The same missed step across many calls gives a supervisor a clearer coaching question. Check the evidence, coach the behavior, then see whether it changes.

Track the outcomeRepeated, verified misses before and after coaching

02

### Find problems beyond the scorecard.

Repeated delivery questions, confusing return instructions or refund delays can point to a process problem. A larger set of conversations helps your team decide which issue to investigate first.

Track the outcomeRepeat contacts and the call reasons behind them

03

### Bring overlooked calls into review.

A small sample leaves most recordings outside the QA process. Evaluating every eligible call puts more policy exceptions and unusual situations in scope for a person to check.

Track the outcomeVerified exceptions and missed exceptions on a held-out set

04

### Spend review time on the findings.

Automated checks can help a reviewer find relevant conversations without searching through recordings one by one. The benefit depends on how often the findings are useful and how much correction they need.

## Why broader review helps.

Independent research / workforce engagement

### AI for Workforce Engagement

The report recommends using AI-assisted QA across all interactions to support coaching and recognition. A wider review set gives supervisors more evidence than a small sample. People still need to check the findings and decide how to use them.

The research describes how to use full-interaction QA; it does not promise a particular time saving or sales increase. Source checked October 9, 2026.

Make it work for your operation

## Measure coverage. Check the findings.

100% coverage means every eligible recording completed evaluation. It doesn't mean every finding is correct, or that a person listened to every call.

For a Call1 pilot, check completed, failed and pending calls. Have reviewers validate findings on representative recordings, then measure review time and the business outcome you want to improve.

Call1's target is full recorded-call evaluation on your hardware. The project is in progress; capacity and accuracy need to be measured on your call mix.
