Service Level Requirements (SLR)
It is the collection of requirements that is gathered by the IT service provider detailing the service requirements with respect to description of the service, availability, capacity, continuity, service level objectives, service level targets, suppliers needed, roles and responsibilities needed, etc.
SLR’s are the initial documents prepared by the service provider, with reference to the discussions made with the customer. Based on the SLR’s, service level objectives and service level targets will be drafted, negotiated, agreed and consolidated into SLA’s.
- To define the functionality and non-functional requirements of the IT service.
- To define the core service, enabling service, and enticing services.
- To define the utility and warranty specifications.
- To capture all the customer requirements as defined without missing any information.
Transfiguration of SLR to SLA
|1||Requirement understanding from customer||
|2||Drafting SLR’s||After gathering requirements, the service level management team and design coordination manager will refine those gathered requirements and will document them into a document called service level requirements. Drafted SLR’s are then sent to the customer for their consent. If the customer doesn’t agree, then the requirements are gathered again.|
|3||Approved SLR||If the drafted SLR’s are as per customer expectations, then the customer would approve the SLR’s.|
|4||Preparation of SLO’s and SLT’s||Based on the approval of SLR’s, SLO’s and SLT’s are prepared by the service level management team.
SLT: Targets, which are SMART (Specific, Measurable, Achievable, Relevant, and Timebound) and is usually based on KPIs.
SLO: Objectives, which define the service description and criteria.
