What is a Service Level Agreement (SLA)?
A Service Level Agreement (SLA) is a contractually agreed document that measurably defines the quality parameters of a service. In public IT and service tenders, SLAs are central components of the service description and contract design.
Core Elements
Availability:
| SLA Level | Availability | Max downtime/year |
|---|---|---|
| Standard | 99.0% | 87.6 hours |
| Extended | 99.5% | 43.8 hours |
| High | 99.9% | 8.76 hours |
| Very high | 99.99% | 52.6 minutes |
Response Times:
| Priority | Description | Typical Response |
|---|---|---|
| P1 – Critical | Total outage | 15-30 minutes |
| P2 – High | Major limitation | 1-2 hours |
| P3 – Normal | Limited with workaround | 4-8 hours |
| P4 – Low | Cosmetic, feature request | Next business day |
SLA Management in Procurement
In the tender: SLA requirements defined in specifications; bidders must explain compliance; SLA fulfillment can be an award criterion.
In the contract: SLAs as contract annexes; reporting obligations; escalation levels; penalty/bonus schemes (service credits).
Penalty and Bonus Schemes
| SLA Fulfillment | Consequence |
|---|---|
| > 100% (over-delivery) | Bonus |
| 100% - target | No adjustment |
| < target | Service credits (penalty) |
| < minimum | Special termination right |
SLA Types in Public Procurement
- IT Operations: Availability, backup cycles, RTO/RPO
- Software Development: Sprint velocity, bug fix times, code quality
- Managed Services: Ticket processing, escalation, capacity management
- Cloud Services: Availability, data portability, security SLAs
Common Mistakes
- Unrealistic SLAs no provider can meet
- Vague formulations instead of concrete metrics
- No monitoring and reporting obligations
- Missing penalty clauses
- Forgetting maintenance windows in SLA calculations
