Call Centre KPIs: The Metrics Every Sri Lankan Call Centre Manager Should Track

Ask a call centre manager how the team did last week and you’ll often hear “it was busy”. Busy isn’t a measure. Without the right numbers you can’t tell whether customers waited too long, whether agents solved problems on the first call, or whether you need two more people on the Monday morning shift.

This guide is for managers and team leaders who run an in-house call centre in Sri Lanka, whether it’s a customer service hotline, a sales desk or a support line for a bank, insurer, hospital group, telco or retailer. It covers the call center KPIs that matter most, how each one is worked out, what tends to push it up or down, and how to turn the numbers into decisions instead of a monthly report nobody reads.

Why KPIs matter more than call volume

Call volume tells you how much work arrived. KPIs tell you how well you handled it. Sri Lanka’s large banks, telcos and insurers have run big contact centres for years, and customers now compare every hotline against the best one they’ve used. A caller who waits on hold for ten minutes, or has to explain the same problem three times, doesn’t care that you had a busy day.

Good KPIs help you:

• Staff the right number of agents for each hour, instead of guessing.
• Spot problems early, such as a new product causing a wave of confused calls.
• Coach agents fairly, using the same measures for everyone.
• Show senior management what the call centre delivers and what it needs.

The core call center KPIs

You don’t need 70 metrics. Most well-run teams watch a short list closely and look at the rest when something changes.

1. Service level

The share of calls answered within a target time. A common starting point is 80% of calls answered within 20 seconds, but the right target depends on your customers and what they’re calling about. A bank’s card-blocking line needs a tighter target than a general enquiries line.

Formula: calls answered within target time ÷ total calls offered × 100.

2. Average speed of answer (ASA)

The average time callers wait in the queue before an agent picks up. It’s the number customers feel most directly. Watch it by hour, not just by day, because a good daily average can hide a painful 9am peak.

3. Abandonment rate

The share of callers who hang up before reaching an agent. A rising abandonment rate usually means queues are too long or the welcome menu is too slow. Some systems exclude callers who hang up within the first few seconds, so check how your reports count it before comparing months.

Formula: abandoned calls ÷ total calls offered × 100.

4. First call resolution (FCR)

The share of issues solved on the first contact, with no repeat call needed. FCR is one of the strongest signals of customer satisfaction and of cost, because every repeat call is work you’ve already paid for once. Measure it with a short follow-up survey, or by tracking whether the same number calls back about the same issue within a set number of days.

5. Average handle time (AHT)

Talk time plus hold time plus after-call work, divided by the number of calls handled. AHT drives how many agents you need, so it matters for planning. Be careful using it as a target for individual agents: pushing AHT down too hard teaches people to rush callers off the phone, and FCR drops.

Formula: (total talk time + total hold time + total after-call work) ÷ calls handled.

6. Customer satisfaction (CSAT)

A short rating at the end of the call, often by SMS or a quick IVR survey: “How satisfied were you with today’s call, from 1 to 5?” Keep it to one or two questions, and offer it in Sinhala, Tamil and English so you hear from all your customers, not just one group.

7. Occupancy and agent utilisation

Occupancy is the share of logged-in time agents spend actually handling calls or after-call work. Too low and you’re overstaffed. Too high for too long and people burn out, take more leave and eventually resign, which is expensive because every new agent needs weeks of training.

8. Schedule adherence

Whether agents are logged in and available when the roster says they should be. It sounds basic, but a few late returns from lunch can wreck a service level during a peak.

9. Quality score

A score from listening to a sample of calls against a checklist: greeting, verification, accuracy, tone, compliance and closing. This is where call centre quality assurance lives. It catches the things numbers miss, such as an agent who closes calls quickly but gives wrong information.

10. Outbound KPIs (if you make calls)

For sales or collections teams, add contact rate (calls that reach the right person), conversion rate (calls that end in a sale, payment or booking) and calls per agent per hour. Track these separately from inbound, because the two kinds of work behave differently.

How the KPIs pull against each other

KPIs are linked, and improving one can damage another. The common trade-offs:

If you push this…	…watch out for this
Lower AHT	Lower FCR and CSAT, as calls are rushed
Higher service level	Higher staffing cost and lower occupancy
Higher occupancy	Agent fatigue, absence and staff turnover
More quality checks	Less supervisor time for live coaching

That’s why the best dashboards show a few KPIs side by side. A team leader looking at AHT alone might think the shift went well. Seen next to a falling FCR, it tells a different story.

Setting targets that fit your call centre

Industry averages are a starting point, not a goal. Set your targets from your own data:

1. Measure for a month first. Get an honest baseline before you set any targets.
2. Separate call types. A complaint line and a sales line shouldn’t share one AHT target.
3. Plan for local peaks. Salary week, festive seasons such as Avurudu and Christmas, monsoon disruptions and product launches all change call patterns. Look at the same weeks last year if you have the data.
4. Agree targets with team leaders. People work towards numbers they understand and believe are fair.
5. Review every quarter. As your systems and team improve, targets should move.

Turning numbers into action

A KPI report only helps if it changes what happens on the floor. A simple routine works for most teams:

• Live, during the shift: watch queue length, ASA and agents available, so supervisors can move people onto the phones when a queue builds.
• Daily: review service level, abandonment and any unusual spikes with team leaders.
• Weekly: check FCR, CSAT and quality scores, and choose one or two coaching topics.
• Monthly: report trends to management, together with the staffing or system changes you need.

When the same issue keeps coming up, fix the cause rather than the call. If many callers ask the same question, a clearer IVR menu, an SMS update or a website FAQ can take those calls out of the queue altogether.

What your call centre system should give you

You can’t manage KPIs you can’t see. Spreadsheets filled in by hand at the end of the month are always late and often wrong. When you review your call centre software, check:

• Whether reports show service level, ASA, abandonment and AHT without manual work.
• Whether supervisors can see queues and agent status during the shift.
• Whether calls can be recorded and sampled for quality checks.
• Whether call data can connect with your CRM, so FCR and repeat calls are easier to track.
• Whether reports can be split by queue, team, hour and call type.

Digital Urgency Call Centre is offered in Standard, Premium and Enterprise tiers, and reporting needs differ a lot between a ten-seat hotline and a large multi-team operation. Request a quote and we’ll confirm in writing which reports and supervisor tools come with each tier before you commit.

Getting started

Pick five KPIs to begin with: service level, abandonment rate, first call resolution, average handle time and customer satisfaction. Measure them honestly for a month, share them with your team leaders, and agree on one improvement to work on. Add the rest as the habit sticks.
