3.1PRINCIPLES 3.2POLICIES

This section describes some of the key principles of Service Transition that will enable service providers to plan and implement the Service Transition best practices. These principles are the same irrespective of the organization; however, the approach may need to be tailored to circumstances, including the size, distribution, culture and resources.

3.1 PRINCIPLES SUPPORTING SERVICE TRANSITION

Service Transition is supported by underlying principles that evolve from Service Strategy considerations and underpin the Service Transition practices and approach. These principles, around understanding what a service is and how it delivers value to the business, provide the foundation for Service Transition.

3.1.1 Define a Service
The Service Strategy publication describes the framework for defining a service. The value of a service is defined within the context of customers and contracts within an eco-system that is commonly referred to as the business environment. Figure 3.1 illustrates the service provider assets used to deliver services to the business and customers.

Resources are tangible and intangible assets that are owned or controlled by the service provider or the organization for conversion into final products or services that are utilized by customers. Resources are converted into goods and services using knowledge, skills, experience, processes, systems and technologies, which are by themselves a special category of intangible assets called capabilities. This is described further in Service Strategy.

Figure 3.2 Services provide value by increasing the performance of customer assets and removing risks The term asset is used to refer either to capabilities or resources, or both depending on the surrounding context.

Services are a means for providing value to customers as shown in Figure 3.2. They are a means by which one business unit delivers value to one or more other business units, or to sub-units within itself. In this publication, business units that deliver services are commonly referred to as service providers or service units and those that use services are called customers or simply business units.

3.1.2 Service Utilities And Warranties
The utility of a service is defined in terms of the business outcomes that customers expect the service to support and the constraints it will remove. This utility is in the form of enhancing or enabling the performance of the customer assets, and contributing to the realization of business outcomes.

Example of utility
In the case of the lending division of a bank (customer), the utility of a credit-check service is that it allows the lending process (customer assets) to determine the creditworthiness of borrowers so that loan applications may be approved in a timely manner after calculating all the risks associated with the borrower (supported outcome).

A warranty is an assurance that some product or service will be provided or will meet certain specifications. Three characteristics of warranty are that it:

It is important to understand that the three aspects of warranty are valid for all services though one aspect may be more critical than another. Indeed, the primary value proposition in some services is high-availability, continuity and security.

3.2.10 Anticipate And Manage Course Corrections
Course corrections
When plotting a long route for a ship or aircraft, assumptions will be made about prevailing winds, weather and other factors, and plans for the journey prepared. Checks along the way - observations based on the actual conditions experienced - will require (usually minor) alterations to ensure the destination is reached. Successful transition is also a journey - from the 'as is' state within an organization towards the 'as required' state. In the dynamic world within which IT Service Management functions, it is very often the case that factors arise between initial design of a changed or new service and its actual transition. This means the need for 'course corrections' to that Service Transition journey, altering the original Service Design planned course of action to the destination the customer needs to reach.
