Service level agreement
An SLA records a common understanding about services, priorities, responsibilities, guarantees and warranties between parties where one party is the customer and the other is the service provider. An SLA will need to cover support services, hours and fees, and service levels and credits. It is very common with the provision of software.
It is important that both parties are clear exactly what services are being provided and how they are to be measured.
Issues to consider include:
- severity of impact on the business resulting from a fault in the service
- the tool to measure availability and how often the measurements are taken to minimise the potential for disputes
- if the SLA is to have a term of years, it would be desirable for the parties to include rules about how performance standards will improve over time.
This is the fee to be paid to the supplier for providing the services.
The hours during which support is to be provided will vary depending on the service. For software, this can range from constant
support, seven days a week, 24 hours a day to business hours only of
This is the mechanism by which the customer is compensated for economic loss as a result of the drop in performance and which motivates the supplier to rectify poor service delivery.
The timing of when service credits are triggered will vary, but they should apply only in situations where the performance was inadequate and below an acceptable range of supplier performance.
