Service level agreement

What is an SLA?

A service level agreement (SLA) is a contractual agreement between a service provider and a customer. It defines the performance standards, service targets and quality requirements that must be met when providing services. Specific metrics and criteria are defined that reflect both the customer's expectations and the service provider's obligations. SLAs are used in many areas – particularly frequently in IT, telecommunications and contact centers.

Important components of an SLA

An SLA usually comprises several core elements that together form a transparent basis for cooperation:

• Service description: The services provided by the service provider are defined – such as IT support, customer service or the operation of a network infrastructure.

• Key performance indicators (KPIs): Measurable targets such as availability, response times to critical requests and the maximum processing time for specific concerns are defined.

• Availability and operating times: This regulates when the service must be available – for example, around the clock or during business hours – and specifies maintenance windows that must not affect the agreed availability.

• Troubleshooting and escalation: How to deal with faults is describe, including escalation levels if the problem is not resolved on time and measures to avoid recurring faults.

• Penalties and incentives: Agreements on contractual penalties or service credits for non-compliance as well as possible bonuses for above-average performance ensure clear obligations.

• Measurement and reporting: The service provider undertakes to regularly document service quality, for example in the form of monthly reports, dashboards or audits.

SLA in the contact center

In the contact center, the SLA plays a central role in managing service quality and customer experience. Typical SLA key figures in this environment are:

• Response time: How quickly an agent responds to incoming calls, emails or chats.

• Maximum waiting time: Limit on the time a customer can spend on hold.

• Resolution time: Period of time in which a request must be fully processed or a problem resolved.

A precisely formulated SLA not only helps with internal control, but also with building external trust.

Advantages of an SLA

A well-structured service level agreement offers numerous advantages - for both the service provider and the customer:

• Clarity and transparency: both sides know what is expected and what services are guaranteed.

• Measurable standards: The defined KPIs make performance verifiable and comparable.

• Higher customer satisfaction: Reliable service quality strengthens customer loyalty.

Trusting cooperation: Fixed agreements and transparent monitoring create a stable basis for long-term business relationships.
