Service Level Agreements (SLAs) and Operational Level Agreements (OLAs) sit at the core of IT Service Management, and they're easy to mix up. You've probably run into SLAs in conversations about customer service and support. OLAs are the piece that explains how internal teams coordinate to keep the promises an SLA makes.
This guide covers what each agreement is for, how they differ, how they work together, and how to turn them into practical SLA tiers for your internal IT services.
What are Service Level Agreements (SLAs)?
A Service Level Agreement (SLA) is a formal contract between a service provider and its customer. It defines the expected level of service and holds the provider accountable for meeting those standards. This isn't just a verbal agreement or a handshake; an SLA is a binding contract that typically includes measurable performance metrics, such as response times, uptime guarantees, and issue resolution timelines.
Think of an SLA as a promise the service provider makes to the customer. The customer knows exactly what to expect in terms of performance, and the provider knows what they must deliver. The value of SLAs is that they eliminate ambiguity. If the SLA states that response times must be under 15 minutes, then both parties can measure performance against that specific metric.
In today's digital operations, where services need to be available around the clock, SLAs give customers a clear reference point. They know they're covered, and if the service falls short, there's a defined course of action, often including penalties or compensation for any downtime or disruption.

What are Operational Level Agreements (OLAs)?
While SLAs manage expectations between a service provider and a customer, Operational Level Agreements (OLAs) are like the behind-the-scenes contracts that make sure everything runs smoothly within the organization. OLAs are internal agreements between different departments or teams that support the overall service delivery.
For example, imagine an IT support team that needs to ensure their ticketing system operates efficiently, and the infrastructure team is responsible for keeping the servers running. They create an OLA to define exactly how they’ll work together to ensure that the IT team can meet its SLA commitments to customers. If the infrastructure team needs to maintain 99.9% uptime, the OLA will spell out the roles, responsibilities, and timelines to meet that goal.
OLAs are the glue that holds internal processes together. Without them, the different departments might be working at cross-purposes, resulting in delays, bottlenecks, or even service disruptions. Simply put, OLAs keep the internal machine well-oiled, so the service provider can keep their SLA promises.
SLA vs OLA: What is the difference?
Here's the heart of the matter. SLAs and OLAs can look similar, but their purpose and audience are entirely different. The table sums up the six differences; the sections below unpack each one.
Difference 1: Audience
SLAs are created for external customers. They define the level of service the customer can expect from the service provider. On the other hand, OLAs are designed for internal teams. They outline how different departments within an organization will work together to meet the terms of the SLA.
SLAs are often legally binding and can include penalties if the service provider fails to meet the agreed-upon standards. OLAs, however, are internal documents that are enforced through management oversight rather than legal obligations.
Difference 2: Focus
The primary focus of an SLA is to ensure that the customer receives a certain level of service, whether it’s uptime, response time, or support. The focus of an OLA, meanwhile, is on the internal processes that enable the organization to meet those SLA goals.
SLAs are outward-facing, while OLAs are inward-facing. One governs the relationship between a service provider and its customer, while the other manages the relationship between internal teams.
Difference 3: Metrics
SLAs typically include metrics that directly affect the customer experience, such as service availability, uptime guarantees, or response times. OLAs, on the other hand, focus on internal performance metrics, such as how quickly the IT team responds to requests from other departments.
The metrics in an SLA are designed to hold the service provider accountable to the customer, while the metrics in an OLA ensure that internal teams are working efficiently and supporting the service delivery process.
Difference 4: Enforceability
SLAs are legally enforceable agreements. If a service provider fails to meet the terms of the SLA, the customer may be entitled to compensation, such as service credits or other penalties. OLAs, in contrast, are not legally binding. They are internal agreements that rely on managerial oversight and team collaboration.
While failure to meet an SLA can result in legal or financial consequences, failure to meet an OLA typically results in internal performance reviews or process adjustments.
Difference 5: Scope
SLAs cover the full range of services provided to the customer, from uptime guarantees to customer support. OLAs, however, have a narrower focus. They deal specifically with the internal processes that support the service delivery outlined in the SLA.
In other words, the scope of an SLA is customer-centric, while the scope of an OLA is team-centric. Both are essential, but they operate on different levels.
Difference 6: Visibility
SLAs are shared with the customer to provide transparency into service expectations and performance. Customers need to know what they can expect from the service provider, and the SLA provides that clarity. OLAs, however, are internal documents that are not shared with the customer.
While SLAs are designed to give the customer peace of mind, OLAs are designed to ensure that internal teams are working together effectively. They’re more about operational efficiency than customer transparency.
5 benefits of Operational Level Agreements
- Improved collaboration between teams. An SLA promises the customer a service level, but hitting it depends on internal teams pulling in the same direction. An OLA spells out each team's part in the handoff, which replaces the blame game with clear ownership.
- Internal accountability. When every team has defined metrics to hit, there's no ambiguity about who owns what. That makes gaps easy to spot and address before they reach the customer.
- Streamlined service delivery. Aligned teams resolve problems like server downtime or technical glitches faster. Smoother internal handoffs translate directly into a better customer experience.
- Cost efficiency. Clear roles cut the time lost to escalations and rework, which lowers the cost of resolving issues. Fewer delays and less downtime keep operations lean.
- Consistency in service quality. A shared framework keeps service quality steady no matter which team is involved, and that consistency builds the kind of trust that keeps customers around.
How to write an OLA?
Creating a solid OLA takes attention to detail and a clear understanding of internal team roles. Here's a step-by-step guide.
Step 1: Identify the services and teams involved
Before you can draft an OLA, you need to identify the services the agreement will cover. What are the internal services that directly affect the SLA? Once you’ve pinpointed these services, it’s time to identify the teams responsible for delivering them.
This step is about gathering information. Get input from every team involved to understand their roles and how they contribute to service delivery, so everyone is on the same page before a word is written.
Step 2: Define responsibilities for each team
Now that you know which teams are involved, it’s time to outline their responsibilities. Be as clear and specific as possible.
For example, if the infrastructure team is responsible for maintaining server uptime, outline exactly what that entails. If the network team is responsible for resolving connectivity issues, provide specific timelines and response expectations.
Clear responsibilities prevent any overlap or gaps in service delivery. Each team should know precisely what they’re accountable for, and there should be no ambiguity about who handles what.
Step 3: Set measurable goals and timelines
Just like SLAs, OLAs should include measurable goals and timelines. This could include metrics such as response time, resolution time, or compliance with specific internal processes. Measurable goals allow teams to track their performance and adjust if necessary.
Make sure these timelines align with any customer-facing SLAs. If the SLA guarantees 99.9% uptime, then the OLA should outline how each team will contribute to maintaining that uptime.
Step 4: Define the escalation process
What happens if a team is unable to meet its obligations? That’s where the escalation process comes into play. Clearly define what actions will be taken if a team falls short, including who is responsible for resolving escalated issues.
Escalation processes ensure that problems don’t languish without a solution. By having a plan in place, teams can address issues before they affect the overall service delivery.
Step 5: Review and get approval from all teams
Once the OLA is drafted, it’s crucial to review it with all the involved teams. Make sure everyone agrees on the terms and expectations. This is also an opportunity to identify any potential gaps or areas that need clarification.
Getting buy-in from every team ensures that the OLA is not only practical but also achievable. Once everyone is on board, you can finalize the agreement and begin implementing it.
Designing SLA tiers for internal IT services
The comparison above sets SLAs and OLAs side by side. This section is the practical next step: defining the service levels IT commits to internally—the tiers that tell the business how quickly it will respond and resolve, based on priority.
A simple tiered model might look like this:
Priority is what decides which tier a ticket lands in, so it's worth agreeing on a clear priority matrix first — one that weighs impact against urgency. And each tier only holds up if the teams behind it commit to their part: the Tier 1 response target above, for example, depends on an OLA with whoever owns the affected infrastructure. Every SLA tier you promise the business rests on the OLAs underneath it.
In InvGate Service Management, you can run multiple SLA policies at once, each tied to its own priorities, services, and business hours, so every tier is tracked and escalated on its own clock.
Measuring success for OLAs
It’s not enough to simply write an OLA—you need to measure its success to ensure it’s working as intended. Here’s how you can measure the effectiveness of your OLAs:
1. Response time
One of the simplest metrics to track is response time. How quickly do internal teams respond to service requests or issues? A quick response time signals that teams are aligned and working efficiently.
Slow response times can point to a breakdown in communication or workflow. Tracking this metric lets you find and fix those inefficiencies before they affect the SLA.
2. Resolution time
Like response time, resolution time or time to resolution is a critical metric. It tracks how long a team takes to fully resolve an issue once it's identified. Faster resolution means better overall service delivery.
Monitoring resolution times helps you spot bottlenecks. If one team consistently takes longer, it may be time to revisit the OLA and add resources or support.
3. Compliance with goals
Compliance is all about ensuring that teams are meeting the goals outlined in the OLA. This could include anything from maintaining server uptime to resolving technical issues within a specified timeframe.
Regularly tracking compliance ensures that all teams are staying on track. If compliance rates drop, it’s a sign that the OLA may need to be adjusted to reflect changing priorities or workloads.
4. Cross-team collaboration
One of the more qualitative ways to measure success is to evaluate cross-team collaboration. Are teams communicating effectively? Are there any breakdowns in the process?
While harder to measure than response or resolution times, gauging the quality of cross-team collaboration can give you insights into the overall health of your internal operations.

Frequently Asked Questions (FAQs)
What is the main difference between an SLA vs OLA?
SLAs are external agreements with customers, while OLAs are internal agreements between departments.
Why are OLAs important?
OLAs ensure that internal teams are aligned and working together to meet the terms of the SLA, leading to more efficient service delivery.
Can an SLA exist without an OLA?
Yes, but without OLAs, it’s harder for internal teams to coordinate, which can lead to issues meeting SLA terms.
How do you measure the success of an OLA?
Metrics like response time, resolution time, compliance rates, and cross-team collaboration can be used to measure OLA success.
What happens if an OLA isn't met?
While there aren’t legal penalties, failure to meet an OLA can lead to performance reviews and adjustments to internal processes.
Where do underpinning contracts fit next to SLAs and OLAs?
An underpinning contract (UC) is the equivalent of an OLA, but with an external supplier rather than an internal team. Where an OLA commits your own departments to the response and resolution times behind an SLA, a UC does the same for a third party, such as a cloud host or a hardware maintainer. If any part of your SLA depends on an outside provider, the UC is what makes that dependency enforceable.
