Service Level Management

Updated: Apr 26



Service level management is essential to ensure service delivery aligns effectively with business needs.

The primary aim is to define and maintain clear business-oriented targets for services that meet and enhance customer and business requirements.

The Service Level Management practice supports the establishment of service expectations and monitoring their fulfilment, ensuring that the service outputs align with agreed-upon goals.


Service level management encompasses the activities and processes required to establish, manage, and continuously improve service levels to meet business objectives.

It involves negotiating, documenting, and monitoring service level agreements (SLAs) defining service provisions' quality and scope.

The scope of service level management includes setting up metrics that reflect service performance and involves regular reviews and adjustments to align with changing business needs and technological advancements.

Key Benefits

Implementing structured service-level management brings several benefits, including;

  • Improved consistency in service delivery

  • Heightened customer satisfaction

  • Enhanced efficiency in resource utilisation.

By aligning services closely with business objectives, organisations can ensure more predictable outcomes and better manage customer expectations, leading to a more stable and reliable service environment.

Basic Concepts and Terms

Below are some of the pivotal terms that are crucial to mastering service-level management:

  • Service Level Agreement (SLA): An SLA is a formal document defining the service level a customer expects from a service provider. It outlines the metrics by which that service is measured and the remedies or penalties should agreed-upon service levels not be achieved. It acts as a cornerstone of accountability and clarity between the two parties.

  • Service Quality refers to the totality of a service's features and characteristics that affect its ability to satisfy stated or implied needs. It is a broad measure that assesses a service's performance, reliability, and outcome in meeting the requirements specified in the SLA.

  • Key Performance Indicators (KPIs): These are specific metrics used to quantitatively measure the success in achieving critical business objectives. In service level management, KPIs are used to assess the efficiency and effectiveness of the service being provided, helping to gauge performance levels and guide decision-making.

  • Metrics: In service level management, metrics are the specific standards or measurements used to evaluate the quality of service delivery. They provide a means to quantitatively measure how well the service provider meets the agreed-upon service levels.


Service level management involves several critical processes that ensure services meet the agreed-upon standards and adapt to changing business requirements.

Here are the main processes involved in effective service level management:

Management of SLAs (Service Level Agreements)

  • Definition of Customer Requirements: This involves identifying and documenting the service needs from the customer's perspective, which could vary significantly depending on whether the services are standard or tailored.

  • Viability Analysis: Examines whether the customer's requirements can be met with available resources and determines the potential costs.

  • Drafting an SLA: Involves creating a draft SLA based on the viability analysis, which is then presented to the customer for review.

  • SLA Negotiation: This entails discussions and revisions of the draft SLA to meet the service provider's and the customer's needs.

  • SLA Communication and Enablement: Once the SLA is agreed upon, the necessary service changes and communications are initiated to enable the agreed service levels.

  • SLA Review: Regular reviews of the SLA are conducted to ensure it remains relevant and effective. Adjustments or reaffirmations are made as needed.

  • SLA Prolongation/Withdrawal: The agreement may be extended or terminated depending on the ongoing need for the service and the outcome of SLA reviews.

Oversight of Service Levels and Service Quality

  • Customer and User Satisfaction Surveys: Regularly gathering feedback to assess satisfaction with the service provided.

  • Ongoing Service Quality Monitoring: Continuous service performance monitoring against SLA standards.

  • Service Review: Periodic reviews of the overall service quality and performance often lead to identifying improvement opportunities.

  • Service Quality Reporting: Producing reports and dashboards that provide insights into service performance and SLA compliance.

Relationship with Other Practices

Service level management does not operate in isolation; it interacts closely with other ITIL practices to ensure comprehensive and effective service delivery.

According to the original document, here are the critical relationships between service-level management and other ITIL practices:

  • Relationship Management: Service level management closely works with relationship management to understand customer needs and expectations, essential for effective SLA development and maintenance.

  • Service Desk: The service desk plays a crucial role in operational communications with users, which directly impacts service level management by gathering user feedback and addressing service issues that may affect SLA compliance.

  • Supplier Management: Effective service level management requires coordination with suppliers to ensure their contributions meet the agreed service levels managed through supplier management practices.

  • Service Catalogue Management: This practice supports service level management by providing a clear and detailed description of service offerings and their current status, which is crucial for accurate SLA documentation and compliance monitoring.

  • Service Design aligns closely with service level management by ensuring services are designed with clear and achievable service levels. This is critical for meeting customer expectations and achieving SLA targets.

  • Continual Improvement: This practice is tightly linked with service-level management. It aims to identify and implement improvements in service delivery that can enhance SLA performance and customer satisfaction.

Roles & Responsibilities

In the framework of service level management, clearly defined roles and responsibilities are essential for effectively implementing and maintaining service levels.

Based on the information from the original document, here are the key roles involved in service-level management and their responsibilities:

  • Service Level Manager: This role is central to overseeing the service level management process. Responsibilities include defining, negotiating, and managing SLAs, ensuring that all service management processes are aligned with the agreed service levels, and leading the service level review meetings.

  • Business Relationship Manager: This role works closely with the Service Level Manager to ensure that customer needs and expectations are accurately reflected in SLAs. It also involves maintaining customer relationships and ensuring ongoing customer satisfaction.

  • IT Service Owner: This person is responsible for delivering specific IT services. The IT Service Owner ensures that the service meets the agreed standards and liaises with the Service Level Manager to address discrepancies between the delivered service and SLA specifications.

  • Service Desk Manager: This person manages the service desk operations and plays a critical role in the operational aspects of service level management, such as handling customer complaints and issues that may impact SLA compliance.

  • Supplier Manager: Ensures all external suppliers and partners adhere to the agreed service levels as part of the SLAs. This role involves managing supplier performance and coordinating with the Service Level Manager to address service delivery issues.

Implementation Advice

Effective implementation of service-level management requires strategic planning, operational tactics, and ongoing monitoring.

Based on the specifics outlined in the original document, here are key pieces of advice for successful implementation:

Key Metrics

  • Service Performance Metrics: Regularly track and report on metrics such as uptime, response times, and incident resolution times, which are critical for evaluating service performance against SLA standards.

  • Customer Satisfaction Scores: Utilise feedback tools like surveys to measure customer satisfaction, which provides direct insight into the perceived quality of the service.

  • SLA Compliance Rates: Monitor the percentage of service targets being met and identify areas where compliance is lacking, enabling targeted improvements.

Things to Avoid

  • Setting Unrealistic Expectations: Avoid setting service levels that are not achievable with current capabilities, as this can lead to customer dissatisfaction and strained resources.

  • Neglecting SLA Reviews: Regularly review and update SLAs to reflect technological changes, business objectives, and customer needs. Failing to do so can result in outdated agreements that no longer serve the business or customer interests.

  • Poor Communication: Maintain clear and open communication with all stakeholders involved in service delivery. Lack of communication can lead to misunderstandings and misaligning expectations between providers and customers.

Implementing these practices and monitoring these metrics ensures that service level management meets current service expectations and is primed for future challenges and changes in service demands.
