ITIL Flashcards
Services
Services are a means of delivering value to customers without requiring the customer to own specific costs and risks.
Service Management
Service Management is a set of specialized capabilities for delivering value to customers in the form of services. ITIL® is a framework for IT Service Management.
Good Practices
Good practices are best practices which have gained wide acceptance and adoption. In short, Good Practices have withstood the test of time.
Good Practices may come from a number of sources including:
Standards
Public frameworks
Academic research
Proprietary knowledge
The Service Lifecycle
The Service Lifecycle organizes activity around services as the services move from concept through the live environment and into retirement.
Processes
Processes are structured sets of activities designed to achieve a specific objective. Processes have four basic characteristics:
- They transform inputs into outputs
- They deliver results to a specific customer or stakeholder
- They are measurable
- They are triggered by specific events
Functions
Functions are self-contained subsets of an organization intended to accomplish specific tasks. They usually take the form of a team or group of people and the tools they use. Whereas processes help organizations accomplish specific objectives–often across multiple functional groups–functions add structure and stability to organizations.
Functions generally map fairly directly to the organizational chart of an organization and are usually supported by budgets and reporting structures. Processes, by contract, typically do not have budgets and reporting structures. Both functions and processes involve roles.
Roles
Roles are defined collections of specific responsibilities and privileges. Roles may be held by individuals or teams. Individuals and teams may hold more than one role. ITIL® emphasizes a number of standard roles include, most importantly:
Service Owner – Accountable for the overall design, performance, integration, improvement, and management of a single service.
Process Owner – Accountable for the overall design, performance, integration, improvement, and management of a single process.
Service Manager – Accountable for the development, performance, and improvement of all services in the environment.
Product Manager – Accountable for development, performance, and improvement of a group of related services.
The Service Desk
The Service Desk provides a single point of contact between users and the IT organization. The Service Desk processes inbound incidents, service requests, change requests, etc. It usually (but not always) owns and executes the Incident Management process. The Service Desk also acts as a hub for all communications internal to the IT Service Provider.
What are the four basic Service Desk configurations discussed within ITIL?
Four basic Service Desk configurations are discussed within ITIL®:
Local – Users and support staff are located on the same premises or campus.
Centralized – Multiple user locations are serviced by a single support location.
Virtual – Multiple user location are serviced by multiple support locations which by virtue of call routing and other technology are able to appear and respond to user requests as a single entity.
Follow-the-Sun – Identical to a virtual Service Desk, but organized in such a way as to utilize support staff shifts working during normal daylight hours for all user requests coming from any time zone.
Technical Management
The Technical Management function is charged with procurement, development, and management of the technical skill sets and resources required to support the infrastructure and the IT Service Management effort.
Technical Management is typically divided into specialty areas representing different specialized teams or functions within an IT organization, e.g. Networking, Security, Database, Storage, Servers, etc. The primary objective of Technical Management is to ensure that the Service Provider has the right skill sets available to deliver the services it offers.
Application Management
Application Management is concerned with the end-to-end management of applications in the environment. Like Technical Management, a big part of what it does involves cultivation of the specialized skill sets required to support the organization’s applications. Application Management does not replace, but rather executes and is supported by core processes such as Incident Management, Problem Management, Change Management, Availability Management, etc.
IT Operations Management
IT Operations Management is concerned with the day-to-day maintenance of the IT infrastructure and the facilities which house it. It is divided into two sub-functions: Operations Control and Facilities Management.
The Operations Control
The Operations Control sub-function is concerned with regular maintenance cycles associated with infrastructure management. These include such activities as:
Console Management
Backup and restore operations
Media management
Batch job execution
Facilities Management
Facilities Management is concerned with maintenance of the facilities which house IT operations, e.g. data centers, call centers, development facilities, etc. Its areas of responsibility include things like:
HVAC
Fire suppression
Facilities access
Power
The RACI Model
In addition to discussing the four primary functions described above, ITIL also utilizes the RACI model as a generic tool for reviewing and assigning four key roles to any important task or activity. Whereas role assignments are often well-defined within functions, the RACI model holds particular value for ensuring that roles are appropriately filled or covered within processes.
Those in the R = RESPONSIBLE role for a given activity are charged with actually executing or performing the activity or task.
The single entity in the A = ACCOUNTABLE role owns the task or activity and must answer for its outcomes. Only one party can be accountable for a given task/activity.
Those in the C = CONSULTED role review and provide advice and authorization around the task or activity.
Those in the I = INFORMED role receive updates as the task or activity progresses.
Service Strategy
Service Strategy is about the selection of services a Service Provider will offer to customers. Services are selected so that they:
Provide value to customers
Enable the Service Provider to capture value
Fall within cost parameters acceptable to the Service Provider
Fall with risk parameters acceptable to the Service Provider
Service Strategy is also about establishment and management of the broadest policies and standards which govern the way a Service Provider operates.
Business Value of Service Strategy
Service Strategy offers value to Service Providers and customers by:
Ensuring that the services they offer align with business objectives.
Ensuring that the services they offer are likely to offer value.
Ensuring that customers can be charged for the services or that some mechanism exists by which the services allow the value offered by the Service Provider to be recognized.
Ensuring that the Service Provider is in a position to handle the costs and risks associated with the services it offers.
Business Case
A Business Case is a structured and documented justification for investment in something expected to deliver value in return, e.g. an IT Service. Business Cases are used during Service Strategy to evaluate the feasibility and desirability of creating and providing various IT Services.
Value Utility and Warranty
The value of service consists of two components: utility and warranty. Services must offer both utility and warranty in order to have value.
Utility, also called ‘fitness for purpose’ involves the ability of the service to remove constraints or increase the performance of the customer.
Warranty, also called ‘fitness for use’ is the ability of the service to operate reliably.
Service Assets
Service Assets or (more generally) assets refer to the resources and capabilities which a Service Provider must allocate in order to offer a service.
Resources
Resources are the raw materials which contribute to a service, such as money, equipment, time, staff, etc. Capabilities are the specialized skills or abilities an organization applies to resources in order to create value. Capabilities include such things as skills, organization, processes, management, etc. Resources and capabilities are both types of assets.
Service Portfolio
The Service Portfolio is the entire set of services under management by a Service Provider. It consists of three major parts: Service Pipeline, Service Catalog, and Retired Services.
Services in the Service Portfolio may be:
Under consideration In design In development In testing In operation
The purpose of the Service Portfolio is to help the Service Provider understand how its resources are allocated toward maximizing the value it offers to customers in the form of services.
Service Belt
In the course of delivering services, Service Provider assets are engaged with customer assets as a means of increasing the performance of customer assets. This causes customer demand for services. Customers express that demand by purchasing services which in turn transfers resources to the Service Provider. The Service Provider uses payment to replace or augment assets it uses to provide the services. This cycle is known as the Service Belt.
Service Strategy
The Service Strategy process (yes, it has the same name as the lifecycle phase!) is concerned with the development of service concepts in preparation for selection of services to be provided. It consists of four major activities:
- Understand the market
a. Who is the customer?
b. What do they value?
c. How do they define value? - Develop the offerings
a. What service offerings would provide value to customers as defined above?
b. How can we as a service provider offer unique or distinctive value? - Develop strategic assets
a. What resources would be required to offer the services identified?
b. What capabilities would be need to offer the services identified? - Prepare for execution
a. How can we prepare to build or develop the service?
b. What are our specific objectives for the service?
c. What specific critical success factors must we meet in order to achieve those objectives?
