2 mins readService Level Agreement (SLA) is a formal document that defines expected services, performance standards, and responsibilities between an HR function and its customers or vendors. In HR, an SLA sets measurable targets for response times, delivery quality, and reporting.
What is Service Level Agreement
An SLA is a written agreement that describes the level of service to be provided, the metrics used to measure performance, and remedies or escalation steps if targets are not met. It translates expectations into clear, measurable commitments.
How does it work
SLAs specify key performance indicators such as time to hire, candidate feedback time, payroll accuracy rate, or HR case resolution time. Parties agree targets, monitoring methods, review intervals, and consequences for breaches.
SLAs help align HR operations with business needs and ensure accountability.
Practical usage and examples
SLAs are used in recruitment, payroll, benefits administration, and outsourced HR services. Typical scenarios include:
- Recruitment SLA: Fill 80 percent of roles within 45 days and provide candidate shortlist in 7 days.
- Payroll SLA: Achieve 99.9 percent on-time and accurate payroll processing each pay period.
- Vendor SLA: Third party manages benefits enrolment with monthly compliance reporting.
