2.1 What Is Service Management?

Service Management is a set of specialized organizational capabilities for providing value to customers in the form of services. The capabilities take the form of functions and processes for managing services over a lifecycle, with specializations in strategy, design, transition, operation and continual improvement. The capabilities represent a service organization's capacity, competency and confidence for action. The act of transforming resources into valuable services is at the core of Service Management. Without these capabilities, a service organization is merely a bundle of resources that by itself has relatively low intrinsic value for customers.

Service Management is a set of specialized organizational capabilities for providing value to customers in the form of services.

Organizational capabilities are shaped by the challenges they are expected to overcome. Service Management capabilities are similarly influenced by the following challenges that distinguish services from other systems of value creation such as manufacturing, mining and agriculture:

Service Management, however, is more than just a set of capabilities. It is also a professional practice supported by an extensive body of knowledge, experience and skills. A global community of individuals and organizations in the public and private sectors fosters its growth and maturity. Formal schemes exist for the education, training and certification of practising organizations, and individuals influence its quality. Industry best practices, academic research and formal standards contribute to its intellectual capital and draw from it.

The origins of Service Management are in traditional service businesses such as airlines, banks, hotels and phone companies. Its practice has grown with the adoption by IT organizations of a service-oriented approach to managing IT applications, infrastructure and processes. Solutions to business problems and support for business models, strategies and operations are increasingly in the form of services. The popularity of shared services and outsourcing has contributed to the increase in the number of organizations who are service providers, including internal organizational units. This, in turn, has strengthened the practice of Service Management, at the same time imposing greater challenges on it.

2.2 What Are Services?

2.2.1 The Value Proposition
Services are a means of delivering value to customers by facilitating outcomes customers want to achieve without the ownership of specific costs and risks. Services facilitate outcomes by enhancing the performance of associated tasks and reducing the effect of constraints. The result is an increase in the probability of desired outcomes. Over the years, organizations have debated the definition of a 'service'. The illustration in Figure 2.1 is an example of the realization that service is really about delivering value to customers.

2.3 Functions And Processes Across Lifecycle

2.3.1 Functions
Functions are units of organizations specialized to perform certain types of work and responsible for specific outcomes. They are self-contained, with capabilities and resources necessary for their performance and outcomes. Capabilities include work methods internal to the functions. Functions have their own body of knowledge, which accumulates from experience. They provide structure and stability to organizations.

Functions are means to structure organizations to implement the specialization principle. Functions typically define roles and the associated authority and responsibility for a specific performance and outcomes. Coordination between functions through shared processes is a common pattern in organization design. Functions tend to optimize their work methods locally to focus on assigned outcomes. Poor coordination between functions, combined with an inward focus, leads to functional silos that hinder the alignment and feedback that are critical to the success of the organization as a whole. Process models help avoid this problem with functional hierarchies by improving cross-functional coordination and control. Well-defined processes can improve productivity within and across functions.

2.3.2 Processes
Figure 2.2 A basic process
Figure 2.2 A basic process

Processes are examples of closed-loop systems because they provide change and transformation towards a goal, and utilize feedback for self-reinforcing and self-corrective action (Figure 2.2). It is important to consider the entire process or how one process fits into another.

Process definitions describe actions, dependencies and sequence. Processes have the following characteristics:

There is often confusion around functions, processes, roles and activities. Functions are often mistaken for processes, and processes mistaken for functions. Service Design, as well as being a stage in the lifecycle of a service, can itself be seen by some organizations as a function, by others as a role or a set of processes or as an activity. Whether or not it is a function, role, activity or set of processes depends entirely on the size, structure and culture of an organization. It is important that however it is defined and implemented within an organization, the success of the function, process, role or activity is measured and continually improved.

2.3.3 Specialization and coordination across the lifecycle
Specialization and coordination are necessary in the lifecycle approach. Feedback and control between the functions and processes within and across the elements of the lifecycle make this possible. The dominant pattern in the lifecycle is the sequential progress starting from SS through SD-ST-SO and back to SS through CSI. That, however, is not the only pattern of action. Every element of the lifecycle provides points for feedback and control.

The combination of multiple perspectives allows greater flexibility and control across environments and situations. The lifecycle approach mimics the reality of most organizationsR, where effective management requires the use of multiple control perspectives. Those responsible for the design, development and improvement of processes for Service Management can adopt a process-based control perspective. For those responsible for managing agreements, contracts and services may be better served by a lifecycle-based control perspective with distinct phases. Both these control perspectives benefit from systems thinking. Each control perspective can reveal patterns that may not be apparent from the other.

2.4 Service Design Fundamentals

2.4.1 Purpose, Goals and Objective
The main purpose of the Service Design stage of the lifecycle is the design of new or changed services for introduction into the live environment. It is important that a holistic approach to all aspects of design is adopted, and that when changing or amending any of the individual elements of design all other aspects are considered. Thus when designing and developing a new application, this shouldn't be done in isolation, but should also consider the impact on the overall service, the management systems and tools (e.g. Service Portfolio and Service Catalogue), the architectures, the technology, the Service Management processes and the necessary measurements and metrics. This will ensure not only that the functional elements are addressed by the design, but also that all of the management and operational requirements are addressed as a fundamental part of the design and are not added as an afterthought.

Key message
A holistic approach should be adopted for all Service Design aspects and areas to ensure consistency and integration within all activities and processes across the entire IT technology, providing end-to-end business-related functionality and quality.

Not every change within an IT service will require the instigation of Service Design activity. It will only be required where there is 'significant' change. Every organization must define what constitutes 'significant' so that everyone within the organization is clear as to when Service Design activity is instigated. Therefore all changes should be assessed for their impact on Service Design activities to determine whether they are significant in term: of requiring Service Design activity. This should be part of the Change Management process impact assessment within the Service Transition publication of ITIL.

2.4.2 Scope

Figure 2.3 Scope Of Service Design

There are five individual aspects of Service Design considered within this publication. These are the design of

The Service Design 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. This developed solution, together with its Service Design Package (SDP - see Appendix A), is then passed to Service Transition to evaluate, build, test and deploy the new or changed service. On completion of these transition activities, control is transferred to the Service Operation stage of the Service Lifecycle. The activities involved in these stages are outlined in section 3. The overall scope of Service Design and the five aspects of design and how they interact are illustrated in Figure 2.3.

The main aim of Service Design is the design of new or changed services. The requirements for these new services are extracted from the Service Portfolio. Each requirement is analyzed, documented and agreed, and a solution design is produced that is then compared with the strategies and constraints from Service Strategy to ensure that it conforms to corporate and IT policies. Each individual Service Design is also considered in conjunction with each of the other aspects of Service Design:

If all the above activities are completed during the Service Design stage, this will ensure that there will be minimal issues arising during the subsequent stages of the Service Lifecycle. Therefore Service Design must consolidate the key design issues and activities of all IT and Service Management processes within its own design activities, to ensure that all aspects are considered and included within all designs for new or changed services as part of everyday process operation.

The ability to measure and demonstrate value to the business requires the capability to link business outcomes, objectives and their underpinning processes and functions to the IT services and their underpinning assets, processes and functions. This value should be articulated by:

Often the design of a major new or changed service will require that design changes are considered, and often affect or are affected by all of the other four phases of the Service Lifecycle. It is essential, therefore, that IT systems and services are designed, planned, implemented and managed appropriately for the business as a whole. The requirement then is to provide IT services that:

With all these pressures on both IT and the business, the temptation - and unfortunately the reality in some cases - is to 'cut corners' on the design and planning processes or to ignore them completely. However, in these situations the design and planning activities are even more essential to the overall delivery of quality services. Therefore, more time rather than less should be devoted to the design processes and their implementation.

In order that effective, quality design can be achieved, even when timescales are short and pressure to deliver services is high organizations should ensure that the importance of the Service Design function is understood and that support is provided to maintain and mature Service Design as a fundamental element of Service Management. Organizations should strive continually to review and improve their Service Design capability, in order that Service Design can become a consistent and repeatable practice, enabling organizations to deliver quality services against challenging timescales. Having a mature Service Design practice will also enable organizations to reduce risk in the transition and operational stages of service.

In general, the key to the successful provision of IT services is an appropriate level of design and planning to determine which projects, processes and services will have the greatest impact or benefit to the business. With the appropriate level of thought, design, preparation and planning, effort can be targeted at those areas that will yield the greatest return. Risk assessment and management are key requirements within all design activities. Therefore all five aspects of Service Design must include risk assessment and management as an integrated, inherent part of everything they do. This will ensure that the risks involved in the provision of services and the operation of processes, technology and measurement methods are aligned with business risk and impact, because risk assessment and management are embedded within all design processes and activities.

Many designs, plans and projects fail through a lack of preparation and management. The implementation of ITIL Service Management as a practice is about preparing and planning the effective and efficient use of the four Ps: the People, the Processes, the Products (services, technology and tools) and the Partners (suppliers, manufacturers and vendors), as illustrated in Figure 2.4.

Figure 2.4 The Four Ps
Figure 2.4 The Four Ps

  However, there is no benefit in producing designs, plans, architectures and policies and keeping them to yourself. They must be published, agreed, circulated and actively used.

In order to ensure that business and IT services remain synchronized, many organizations form committees of senior management from the business and IT organizations. The committee carries the overall accountability for setting governance, direction, policy and strategy for IT services. Many organizations refer to this group as the IT Strategy or Steering Group. (ISG). The function of an ISG is to act as a partnership between IT and the business. It should meet regularly and review the business and IT strategies, designs, plans, service portfolio, architectures and policies to ensure that they are closely aligned with each other. It should provide the vision, set direction and determine priorities of individual programmes and projects to ensure that IT is aligned and focused on business targets and drivers. The group should also ensure that unrealistic timescales, which could jeopardize quality or disrupt normal operational requirements, are not imposed or attempted by either the business or IT. See Figure 2.5.

Figure 2.5 The IT Steering/Strategy Group
Figure 2.5 The IT Steering/Strategy Group

The ISG will include discussions on all aspects of the business that involve IT service, as well as proposed or possible change at a strategic level. Subjects for the ISG to discuss may include:

The IT Steering Group sets the direction for policies and plans from corporate to operational levels of IT organization and ensures that they are consistent with corporate level strategies. See Figure 2.5. The ISG has an important role to play in the alignment of business and IT strategies and plans as illustrated in Figure 2.5. As can be seen, the Service Portfolio is a key source of input to the ISG in its decision-making role, which enables the ISG to:

2.4.3 Value to Business
With good Service Design, it is possible to deliver quality, cost-effective services and to ensure that the business requirements are being met.

The following benefits result from good Service Design practice:

2.4.4 Optimizing Design Performance
The optimizing of design activities requires the implementation of documented processes, together with an overriding quality management system (such as ISO 9001) for their continual measurement and improvement. It is important that when considering the improvement and optimization of the Service Design activities, the impact of the activities on all stages of the lifecycle should be measured and not just the impact on the design stage. Therefore Service Design measurements and metrics should look at the amount of rework activity and improvement activity that is needed on transition, operation and improvement activities as a result of inadequacies within the design of new and changed service solutions. More information on measurement of Service Design can be found in section 8.5.

2.4.5 Processes within Service Design
This publication details processes required in the design phase of the Service Lifecycle. These processes cannot be considered in isolation, as their true value will only be realized when interfaces between the processes are identified and actioned. The following processes are detailed in this publication:

These are only some of the processes described in the ITIL Service Management practice guidance. All processes within the Service Management Lifecycle must be linked closely together for managing, designing, supporting and maintaining the services, IT infrastructure, environment, applications and data. Other processes are described in detail in other publications within the ITIL Service Management Practices core library. The interfaces between every process and every other process need to be clearly defined when designing a service or improving or implementing a process. These interfaces are described in detail in section 4 and include not only the interfaces to each of the Service Design processes, but also interfaces to processes within other stages of the lifecycle.

When designing a service or a process, it is imperative that all the roles are clearly defined. A trademark of high performing organizations is the ability to make the right decisions quickly and execute them quickly. Whether the decision involves a strategic choice or a critical operation, being clear on who has input, who decides and who takes action will enable the organization to move forward quickly.
