ITIL Service Design

The Service Design stage of the ITIL Service Lifecycle provides guidance for the design and development of services and Service Management processes. It covers design principles and methods for converting strategic objectives into portfolios of services and service assets. The scope of Service Design is not limited to new services. It includes the changes and improvements necessary to increase or maintain value to customers over the lifecycle of services, the continuity of services, achievement of service levels and conformance to standards and regulations. It guides organizations on how to develop design capabilities for Service Management. The Service Design stage of the lifecycle starts with a set of new or changed business requirements and ends with the development of a service solution designed to meet the documented needs of the business.


Purpose, Objective Scope and Value of ITIL Service Design[1]

Purpose of ITIL Service Design
The purposes of service design in ITIL are to do the following:

  • Design IT services, governing IT practices, processes, and policies.
  • Realize the strategy of the service provider.
  • Expedite the introduction of services
  • Make sure that service delivery is of high quality, the customers are satisfied, and the service provisions are cost effective.

Objectives of ITIL Service Design
The objectives of ITIL service design are:

  • To design IT services which are so effective that only minimum improvement will be needed during their entire lifecycle.
  • To embed CSI in all the activities of service design to make sure that the solutions become more effective over time.
  • To keep a look out for investment opportunities by identifying changing trends.

Scope of ITIL Service Design
Service design starts with a set of business requirements which are new or changed and it ends with the development of a service solution to meet those requirements. There are five aspects of service design which cover the design of:

  • Service solutions for new or changed services
  • Systems and tools for management information
  • Technology and management architectures
  • The required processes
  • Methods and metrics for measurement

Value of ITIL Service Design
If service design is good, it is possible to deliver services which are of high quality and very cost-effective. It is also possible to ensure that the business requirements are being met. The following benefits are provided by a design approach which is standard and consistent:

  • It reduces the total cost of ownership (TCO)
  • It significantly improves the quality, reliability, and performance of service.
  • It makes the implementation of new services or changing of existing services easy.
  • It helps to improve the IT governance
  • It increases the effectiveness of service management and IT processes.
  • It improves decision-making capabilities.

The overall scope of Service Design and the five aspects of design and how they interact are illustrated in the figure below

Principles of ITIL Service Design[2]

The overall approach of ITIL Service Design is to represent the fundamentals of designing services. The five key aspects of Service Design process are as follows –

  • Designing Service Solution: At the planning stage, the service team chalks a plan of producing services with balancing cost, deadline, budget and business requirements.
  • Designing Management Information Systems and Tools: ITIL service design defines some important Management Information System (MIS), such as service portfolio, configuration management system, capacity management information system and security management information system.
  • Designing of Technology and Architecture: Designing technology brings in technological competencies which take care of designs, plan, and processes aligning with IT policies and strategies.
  • Designing Processes: The process model is one of the elaborate paradigms in ITIL and it helps in the transition, operation, and improvement of services.
  • Designing Measurements and Metrics: Process metrics must be aligned with organizational goals and drilled down to each individual role as in balanced scorecard metrics.


ITIL Service Design Processes[3]

According to official ITIL v3 Documents, there are Eight Well-Defined processes under ITIL Service Design module. Along with that, there are Three Processes which are implicitly-defined by ITIL Documents but those are needed or need to be used throughout this process group.

  • 1) Design Coordination (ITIL Defined): Responsible for proper coordination between all service design activities, processes, and resources. Design coordination ensures the reliable and effective design of new or changed IT services, service management information systems, architectures, technology, processes, information, and metrics.
  • 2) Service Catalogue Management (ITIL Defined): Used to ensure that a Service Catalogue is produced, maintained, and the catalogue contains accurate information about all operational services along with those being prepared to be run operationally.
  • 3) Service Level Management (ITIL Defined): Responsible to negotiate Service Level Agreements with the customers and to design services in accordance with the agreed service level targets. Service Level Management also responsible for monitoring, reporting all Operational Level Agreements and Underpinning Contracts to ensure their appropriateness.
  • 4) Capacity Management (ITIL Defined): Ensures that the capacity of IT services and the IT infrastructure is adequate to deliver the agreed service level targets in a cost-effective and timely manner. Ideally, Capacity Management considers all resources required to deliver the IT service, and plans for short, medium and long-term business requirements.
  • 5) Availability Management (ITIL Defined): Used to define, analyze, plan, measure and improve all aspects of the availability of IT services. It is also responsible for ensuring that all IT infrastructure, processes, tools, roles etc. are appropriate to meet the SLA.
  • 6) IT Service Continuity Management (ITIL Defined): To manage risks that could seriously impact IT services. ITSCM ensures that the service provider, in any situation can meet the minimum agreed Service Levels.
  • 7) Information Security Management (ITIL Defined): Responsible for ensuring the confidentiality, integrity and availability of an organization's information, data and IT services.
  • 8) Supplier Management (ITIL Defined): It ensures that all contracts with suppliers aligned with the business requirement, and that all suppliers meet their contractual commitments.
  • 9) Risk Management: To identify, assess and control risks. This includes analyzing the business assets, identifying threats to those assets, and evaluating the vulnerability of each asset is to those threats.
  • 10) Compliance Management: To ensure IT services, processes and systems comply with organization policies and legal requirements.
  • 11) Architecture Management: To define an outline for the future development of the technology, taking into account the Service Strategy and newly available technologies.

The diagram below illustrates the process flow and connection between each of the processes mentioned above:

ITIL Service Design Roles

The following are all the important roles that are defined within the ITIL service design module.

  • Service Design Manager: The Service Design Manager is responsible for developing quality, secure and resilient designs for new or improved services. This Role is also responsible for producing and maintaining all design documentation.
