ITIL Service Level Management Goal

The primary goal of Service Level Management is to ensure that an agreed level of IT service is provided for all current IT services, and that future services are delivered in line with agreed achievable targets. It also proactively seeks and implements improvements to the level of service delivered to customers and users.

While some organizations may continue to rely on a ‘best endeavors’ approach to service quality, the majority have realized that there needs to be a consistent, agreed and understandable method used for defining and reporting of IT service quality. As the modern IT organization has matured over time to be more akin to any other area of business, there has also been an increased requirement for more formal methods, by which the value of funding and investments into IT are assessed, and performance measured for services provided and capabilities supported. In the context of Service Offerings and Agreements, Service Level Management is the process that seeks to provide consistency in defining the requirements for services, documenting targets and responsibilities, and providing clarity as to the achievements for service quality delivered to customers.

In effect, the process seeks to manage the ‘grey areas’ that are formed between customers and the IT organization, as well as ensuring that the activities performed by various IT groups are coordinated optimally to meet customer requirements. The staff involved (Service Level Management team) are fluent in both technical and business jargon; they resolve disputes between parties (but as a result are sometimes seen as a spy in both camps) and generally work to improve the relationship between the IT organization and the customers it supports.

Terminology

Explanation
Service Level Agreement (SLA): A written agreement between a service provider and their Customers that documents agreed levels of service for a Service.   
Service Catalog: A written statement of available IT services, default levels, options, prices and identification of which business processes or customers use them.      
Underpinning Contract (UC): Contract with an external supplier that supports the IT organization in their delivery of services.
Operational Level Agreement (OLA):

Internal agreement with another area of the same organization which supports the IT service provider in their delivery of services.
Service Level Requirements: Detailed recording of the Customer’s needs, forming the design criteria for a new or modified service.

ITIL Service design processes

The processes included with the Service Design lifecycle phase are:

  • Service Level Management
  • Capacity Management
  • Availability Management
  • IT Service Continuity Management
  • Information Security Management
  • Supplier Management
  • Service Catalog Management.

It is important to note that many of the activities from these processes will occur in other lifecycle phases, especially Service Operation. Additionally, Service Level Management also plays an important role in Continual Service Improvement.

Like all ITIL® processes, the level to which the Service Design processes are required to be implemented will depend on many factors, including:

  • The complexity and culture of the organization
  • The relative size, complexity and maturity of the IT infrastructure
  • The type of business and associated customers being served by IT
  • The number of services, customers and end users involved
  • Regulations and compliance factors affecting the business or IT
  • The use of outsourcing and external suppliers for small or large portions of the overall IT Service Delivery.

Based on these influencing factors, the SOA team may comprise of a single person in a small IT department, or a worldwide network of business and customer oriented groups in an international organization.

ITIL Service Design Packages

Assembling the Service Design Package (SDP)  Upon successful passing of the ITIL 2011 Service Design Lifecycle exam, the student will be recognized with 

 

The information contained within a Service Design Package includes documentation of all aspects of the service and its requirements, in order to provide guidance and structure through all of the subsequent stages of its lifecycle. The information contained within it should address the five major aspects of Service Design that were previously mentioned. A Service Design Package is typically produced for each new IT Service, major Change, or IT Service Retirement.

Service Design Packages 
  • Business Requirements
  • Service Applicability
  • Service Contacts
  • Service Functional Requirements
  • Service Level Requirements
  • Service Design and Topology
  • Organizational Readiness Assessment
  • User Acceptance Test Criteria
  • Service Program
  • Service Transition Plan
  • Service Operational Plan
  • Service Acceptance Criteria

ITIL Service Design Major Concepts

An overall, integrated approach should be adopted for the design activities, covering five major aspects of Service Design:

  1. Service Portfolio: Service Management systems and tools, especially the Service Portfolio for the management and control of services through their lifecycle.
  2. Service Solutions: including documentation of all of the functional requirements, performance criteria, and other resources and capabilities needed and agreed.
  3. Technology architectures: Technology architectures and management architectures and tools required to provide the service.
  4. Processes: Processes needed to design, transition, operate and improve the service.
  5. Measurement systems: Measurement systems, methods and metrics for the services, the architectures and their constituent components and the processes.

The key aspect in the design of new or changed services is to meet changing business needs. Every time a new service solution is produced, it needs to be checked against each of the other aspects to ensure that it will integrate and interface with all of the other services in existence.

ITIL Service Design

The Service Design phase is concerned predominantly with the design of IT Services, as well as the associated or required:

  • Processes
  • Service Management systems and tools
  • Service Solutions
  • Technology architectures
  • Measurement systems.

The driving factor in the design of new or changed services is the support of changing business needs. Every time a new service solution is produced, it needs to be checked against the rest of the Service Portfolio to ensure that it will integrate and interface with all of the other services in existence.
