Look—most KPI guides sound the same.

They throw in a few definitions, maybe a formula or two, and call it “complete.”
It’s not.

Because if you’ve ever actually worked in a contact centre (even for a week), you already know… things are messy. Calls spike randomly. Agents have off days. Customers get angry over stuff you didn’t even cause.

So yeah, metrics matter. A lot.
But only if you understand what they’re really telling you.

 Avaya Contact Center Solutions are monitoring tool experts and are able to assist with establishing a service level for your business before you set your KPI’s.  

Let’s break it down properly.

Why KPIs Still Matter

Here’s the thing.

Customers don’t wait anymore.

They won’t sit on hold for 5 minutes like they did 10 years ago. They’ll just hang up… open another app… and go somewhere else. Done.

A small example:

A telecom company in Hyderabad noticed something weird—their call volume wasn’t dropping, but conversions were. After digging in, they found customers were calling, waiting ~40 seconds, then switching to competitors online.

Forty seconds. That’s it.

So yeah, KPIs aren’t just “nice to track.”
They directly hit revenue.

The 3 Things Every Contact Centre Is Trying to Balance

You’ll hear fancy frameworks, but honestly, it comes down to three things:

  • Speed
  • Quality
  • Cost

That’s the whole game.

Move one, the others react.

You make things faster → quality might drop
You improve quality → costs go up
You cut costs → everything else suffers

And there’s no perfect balance. You just keep adjusting.

The Classic KPIs

Average Speed of Answer (ASA)

This is basically: “How long before someone picks up?”

Simple. But people misuse it all the time.

Yes, lower is better.
No, it’s not everything.

I’ve seen teams hit a 10-second ASA… and still get terrible feedback. Why? Because agents were rushing just to keep numbers low.

So what’s a “good” number?

  • Calls: ~20–30 seconds
  • Chat: under 10 seconds

Anything lower is great—but only if conversations don’t feel rushed.

Abandonment Rate

This one sounds worse than it always is.

It tracks how many people hang up before reaching an agent.

But not every abandoned call is a failure.

Sometimes:

  • The IVR gave them what they needed
  • They got tired and switched to chat
  • Or… they just didn’t feel like waiting

So instead of panicking at the number, ask: why did they leave?

Under 5% is usually fine.
Above 10%? Yeah, you should look into that.

First Contact Resolution (FCR)

If you track only one thing—make it this.

Did the issue get solved in one go?

Because customers don’t care how fast you answer if they have to come back again tomorrow.

Quick story:

A guy named Imran called a bank about a duplicate charge.
Agent #1 explained half of it.
Agent #2 (next day) fixed it completely.

Technically handled well. But for Imran? Annoying.

That’s a failed FCR.

Good contact centres sit around 75–85%.
Anything lower usually means gaps in training or systems.

Average Handle Time (AHT)

Managers love this one. Agents… not so much.

It measures how long a call takes, including after-call work.

Now here’s where it gets tricky.

Lower AHT looks efficient on paper.
But push it too hard and agents start cutting conversations short.

You’ve probably experienced that yourself:
“Anything else I can help you with?” (but clearly they want to end the call)

That’s AHT pressure.

So don’t chase the lowest number.
Chase the right number.

Occupancy Rate

This tells you how busy your agents are.

Too busy? They burn out.
Too free? You’re wasting money.

There’s a sweet spot—usually around 75–85%.

And honestly… once you cross 90%, things start breaking. You’ll see it in mood, tone, and mistakes.

Cost Per Contact

This is where finance teams start paying attention.

Total cost divided by total interactions.

Simple math.

But cutting this blindly is risky.

One company reduced costs by hiring fewer agents.
Short-term win.
Long-term disaster—wait times increased, CSAT dropped, customers left.

So yeah, cheaper isn’t always smarter.

New-Age KPIs

Things have changed a lot in the last few years.

Calls aren’t the only channel anymore. Not even close.

Customer Satisfaction (CSAT)

You’ve seen this:

“Rate your experience from 1 to 5.”

It’s useful. But it has limits.

People usually respond when they’re either very happy… or very annoyed. The middle stays quiet.

Still, anything above 80% is solid.

Net Promoter Score (NPS)

This one’s about loyalty.

“Would you recommend us?”

It’s less about one interaction, more about overall experience.

Good brands aim for +40 or higher.

But honestly? It takes time to improve. You don’t fix NPS overnight.

Customer Effort Score (CES)

This is my personal favorite.

Because it answers a simple question:

“How hard was this for the customer?”

That’s it.

If someone has to:

  • Repeat themselves
  • Switch channels
  • Wait multiple times

That’s high effort. And people hate that.

Lower effort = happier customers. Almost always.

Self-Service Success Rate

With chatbots and help centers everywhere, this matters more now.

Can customers solve issues without talking to anyone?

Example:
Out of 1,000 chatbot sessions, 700 get resolved → 70%

That’s pretty good.

But if people keep dropping off halfway? Something’s wrong.

Omnichannel Resolution

Customers don’t think in channels.

They start on WhatsApp, move to email, then call.

They expect you to keep up.

If your system treats every interaction separately… customers notice. And they get frustrated.

A Real Fix

One mid-sized online store (around 100 agents) was struggling:

  • Long wait times
  • Repeated calls
  • Frustrated customers

Instead of hiring more agents immediately, they tried something else.

They:

  • Improved internal knowledge base
  • Added basic chatbot support
  • Trained agents on top 5 recurring issues

Within a few months:

  • Repeat calls dropped
  • FCR improved significantly
  • Customer complaints reduced

No massive investment. Just smarter adjustments.

Mistakes That Quietly Kill Performance

This part doesn’t get talked about enough.

Chasing one metric too hard
You fix AHT → break FCR
You fix cost → break CSAT

Everything is connected.

Ignoring context
A spike in calls might not be bad. Maybe you launched something new.

Numbers alone don’t tell the full story.

Too many KPIs
I’ve seen dashboards with 20+ metrics.

No one tracks that properly. Not even managers.

Keep it focused. Really.

Which KPIs Should You Track?

Depends on your business.

But a simple starting point:

  • FCR
  • CSAT
  • ASA
  • AHT
  • One cost metric

That’s enough to begin with.

Add more only when you actually use them.

Final Thought

Honestly?

KPIs aren’t the hard part.

Understanding them is.

Anyone can track numbers.
Not everyone knows what to do when they change.

So don’t just collect data.
Pay attention to patterns.

Because that’s where the real insights are.
