A
80
Q

How does ITIL define a Change

A

ITIL® defines a change as the addition, removal, or modification of anything that could have an effect on an IT service. All changes involve risk.

81
Q

What is a Request for Change

A

A Request for Change or RFC is a documented request to alter a service or other Configuration Item. RFCs may be issued by any one: customers, IT staff, users, etc. and are received by the Service Desk and handled via the Change Management process.

82
Q

List and describe the three types of change

A
  • Normal Changes
    • changes which meet predefined criteria that qualify them for handling via the normal change management process
  • Standard Changes
    • changes which are pre-approved for implementation. Generally standard changes are low risk and occur frequently in the environment. Exmaples might be things such as:
      • Password resets
      • New hire procedures
      • Office moves
  • Emergency Changes
    • Changes which meet predefined criteria that qualify them for handling via the Emergency Change Management process. In most environments, Emergency Changes are those which cannot be foreseen and which unless addressed quickly put the environment at high risk of impact. Emergency changes are reviewed by the Emergency Change Advisory Board (ECAB)
83
Q

In ITIL® the entity charged with approval of a Request for Change is called the ___ ___. In most environments, the identity of the ___ ___ varies with the type of change under consideration. For many ordinary changes, the Change Manager may act as the ___ ___. However, for extremely large changes, the ___ ___ may be an executive or even the board of directors.

A

In ITIL® the entity charged with approval of a Request for Change is called the Change Authority. In most environments, the identity of the Change Authority varies with the type of change under consideration. For many ordinary changes, the Change Manager may act as the Change Authority. However, for extremely large changes, the Change Authority may be an executive or even the board of directors.

84
Q

What is the Change Advisory Board

A

The Change Advisory Board or CAB is a group of experts convened by the Change Manager to advise on the approval/rejection and planning for a specific change. The membership of the CAB usually varies with the change under consideration.

85
Q

What is the Emergency Change Advisory Board

A

The Emergency Change Advisory Board or ECAB is a special group convened by the Change Manager to advise on the approval/rejection and planning for Emergency Changes as part of the Emergency Change Management Process. The membership of the ECAB usually includes persons with the experience and organizational authority required to make rapid and often difficult decisions and to accept the consequences of those decisions.

86
Q

What is a Change Model and for what is it used

A

A Change Model is a template or pre-defined set of steps, procedures, and guidelines for execution a specific type of change. Change Models are used to help minimize risk, save costs, and improve the consistency of execution around changes.

87
Q

What is a Release

A

A release is a collection of changes which must be implemented together in order accomplish a specific objective or set of objectives.

88
Q

What is a Release Unit

The Release Unit for a release is selected as part of the

A

A Release Unit is the particular set of configuration items released together for a specific deployment effort.

The Release Unit for a release is selected as part of the Release and Deployment Management process based upon both technical and business criteria.

For example, for the deployment of an accounting package the release unit might be determined to be the accounts payable and payroll modules, but not the tax computation module.

89
Q

In the context of Service Transition generally and, more specifically, in the context of the Service Asset and Configuration Management process, the term Baseline refers to:

A

the documented and validated configuration of a component, system, service, etc.

Baselines are used within Service Asset and Configuration Management to provide a roll-back point useful in managing risk around changes in the environment.

90
Q

What is the Configuration Management System

What is the purpose of the CMS

A

The Configuration Management System is the controlled repository and interfaces for management of information concerning items under configuration control (Configuration Items) in the environment.

The purpose of the CMS is to provide accurate and up-to-date information regarding how the environment is configured. The CMS stores records of Configuration Items in the Configuration Management Database (CMDB). Importantly, the CMS/CMDB differs from a traditional asset database in that it also provides information regarding how Configuration Items are related to each other.

91
Q

What is a Configuration Item

How are Configuration Items tracked

A

A Configuration Item or CI is anything which has significance for the delivery of an IT Service. Configuration Items can include hardware and software, but also documentation, process definitions, facilities, etc.

Configuration Items are tracked using the Configuration Management System which stores records of them in the Configuration Management Database (CMDB). At a bare minimum, the record of a Configuration Item should include a unique identifier and the location of the CI.

92
Q

What is change management concerned with

A

Change Management is concerned with recording, evaluating, approving, testing, and reviewing changes to services, systems, and other Configuration Items.

93
Q

As such Change Management is largely concerned with managing risk associated with change. The major activities which make up the Change Management process include:

A
  • Recording of RFCs
    • involves logging of the RFC in the Change Management system. Recording must include all details required to assess the RFC
  • Review of RFCs
    • involves checking to see if the RFC is complete and free of obvious defects which would make it impractical or impossible to implement
  • Assessment and Evaluation of RFCs
    • involves further review and consideration of the RFC, usually by the Change Advisory Board, for the purpose of determining the desirability and feasibility of the requested change
  • Authorization of RFCs
    • involves identification of the appropriate Change Authority and the determination by the Change Authority to approve or deny the RFC
  • Planning
    • involves identification and scheduling of the activities required to implement the change, including any testing which may be required to manage risk associated with the change
  • Implementation Coordination
  • Review and Closure
94
Q

What is the purpose of Transition Planning and Support

A

Transition Planning and Support provides broader support for large-scale transitions and releases and would be helpful for an organization anticipating an unusual volume of change, as for example would be the case during a merger or acquisition scenario.

95
Q

What is Service Validation and Testing

A

Service Validation and Testing provides separate and more focused support for testing prior to release. Organizations for which quality and error control are of paramount importance might especially benefit from implementation of Service Validation and Testing as a separate process. In such a scenario, Release and Deployment Management would focus more exclusively on deployment/release logistics and testing would become the domain of the new process.

96
Q

What does Evaluation provide?

A

Evaluation provides support for post-release evaluation and confirmation of customer acceptance of new and changed services. It would be useful in situations characterized by customer satisfaction challenges and in situations where other factors might require closer management of customer acceptance.

97
Q

What is the purpose of Knowledge Management

A

Knowledge Management provides support for the capture and effective publishing of knowledge which surfaces during the Service Transition lifecycle phase and elsewhere. From a practical perspective, Knowledge Management belongs in Service Transition simply because Service Transition has responsibility for most testing and validation where the most valuable operational data is gathered prior to release into the live environment.

98
Q

Service Operation overview

A

The Service Operation phase of the Service Lifecycle is concerned with ensuring that services operate within agreed parameters. When service interruptions do occur, Service Operation is charged with restoring service as quickly as possible and with minimizing the impact to the business.

99
Q

Service Operation is the only lifecycle phase in which value is actually realized by customers. Whereas all other phases of the Service Lifecycle contribute to and enable value, it is only experienced during Service Operation.

Service Operation also adds business value by:

A
  • Ensuring that services are operated within expected performance parameters
  • Restoring services quickly in the event of service interruption
  • Minimizing impact to the business in the event of service interruption
  • Providing a focal point for communication between users and the Service Provider organization
100
Q

Because Service Operation is the first lifecycle phase in which the Service Provider organization must respond to rather than plan for and drive user and customer demand, balance is difficult to maintain. Accordingly, ITIL® emphasizes the importance of striving to achieve and maintain balance during Service Operation in the form of specific balances between:

A
  • Reactive and Proactive Focus
  • Internal and External Focus
  • Cost and Quality
  • Stability and Flexibility
101
Q

During Service Operation, the importance and criticality of communication is especially acute. ITIL stresses the importance of communication:

A
  • Between users and the IT Service Provider
  • Between customers and the IT Service Provider
  • Between different processes, functions, teams, etc. within the IT Service Provider
  • Between the IT Service Provider and its suppliers
102
Q

What is an incident

A

An incident is any occurrence which causes or may cause interruption or degradation to an IT Service

103
Q

What is a problem

A

A problem is the unknown underlying cause of one or more incidents. A problem is NOT just a particularly serious incident.

104
Q

What is an error

A

An error is the known underlying cause of one or more incidents.

105
Q

What is a known error

A

A known error is the known cause of an incident for which a workaround also exists.

107
Q

Incident Management - Concerned with/owned by

A

Incident Management is concerned with the rapid restoration of services and with minimization of impact to the business. In most but not all cases the Incident Management process is owned and executed by the Service Desk.

108
Q

Within ITIL, Incident Management consists of a number of basic activities or steps:

A
  • Detection – The incident becomes known by any mechanism, e.g. user call, system alert, etc.
  • Logging – Details of the incident are recorded in the incident management system.
  • Classification – The incident is categorized according to predefined criteria for the purpose of facilitating diagnosis and prioritizing its handling relative to other incidents.
  • Prioritization – The impact and urgency of the incident are determined and factored together to determine its relative priority among other incidents.
  • Investigation and Initial Diagnosis – Additional details regarding the incident are gathered and used along with tools such as the Known Error Database to attempt resolution.
  • Escalation – If necessary, the incident may be forwarded to the appropriate handling group.
  • Resolution and Recovery – Service is restored and users are provided assistance to allow them to resume work.
  • Closure – Successful resolution of the incident is verified with the user, the incident resolution details are recorded, and the incident is flagged as being closed in the incident management system.
109
Q

Problem Management is concerned with the identification and correction of flaws or errors in the environment which cause incidents. Problem Management helps reduce and prevent incidents. Problem Management is broadly divided into two major sub-processes:

A
  • Reactive Problem Management
    • is charged with responding to problems as they arise in the environment, usually driven by the Incident Management process.
  • Proactive Problem Management
    • is charged with proactively seeking out improvements to services and infrastructure before incidents occur.
110
Q

Problem Management uses techniques such as Kepner-Tregoe, Ishikawa diagramming, and Fault Tree Analysis to identify the ___ ___ of incidents. Once the ___ ___ of an incident is determined, Problem Management may issue a ___ ___ ___ to initiate action toward implementation of a permanent fix for the underlying cause or, if a permanent solution is not feasible, may assist in the development of a ___ ___ for use in restoring service and minimizing the impact of associated incidents.

A

Problem Management uses techniques such as Kepner-Tregoe, Ishikawa diagramming, and Fault Tree Analysis to identify the root cause of incidents. Once the root cause of an incident is determined, Problem Management may issue a Request For Change to initiate action toward implementation of a permanent fix for the underlying cause or, if a permanent solution is not feasible, may assist in the development of a Work Around for use in restoring service and minimizing the impact of associated incidents.

111
Q

What is the Known Error Database (KEDB)

A

The production and maintenance of the Known Error Database (KEDB) is one of the most important outputs of the Problem Management process. The Known Error Database is used by the Incident Management process to more rapidly resolve incidents.

112
Q

Event Management is concerned with:

A

Event Management is concerned with detection of events in the infrastructure and with selection of appropriate response actions. By facilitating early detection of incidents, Event Management helps reduce the number of incidents which impact users and can greatly improve the performance of the Incident Management process itself.

113
Q

As described earlier, an ___ is any change of state which has significance for the delivery of a service. As such, ___ ___ mainly focuses on IT detecting and addressing issues at the infrastructure level and is most commonly a largely automated process.

A

As described earlier, an Event is any change of state which has significance for the delivery of a service. As such, Event Management mainly focuses on IT detecting and addressing issues at the infrastructure level and is most commonly a largely automated process.

114
Q

What are the three basic types of events and their descriptions:

A

Informational - No action is required. The event information is logged for potential future reference

Warning - An infrastructure item is aproaching a predefined performance or capacity threshold which could cause an incident or require intervention

Exception - An infrastructure item has exceeded a threshold or is no longer operating within defined parameters. Intervention is required

115
Q

Service Request Fulfillment is the process charged with assisting users in situations where no ___ ___ or ___ is involved. Service Request Fulfillment provides a means of addressing common user requests for non-incident support, new equipment, training, etc. Service Request Fulfillment frequently makes use of ___ ___ and automation to meet user requests more efficiently.

A

Service Request Fulfillment is the process charged with assisting users in situations where no service degradation or interruption is involved. Service Request Fulfillment provides a means of addressing common user requests for non-incident support, new equipment, training, etc. Service Request Fulfillment frequently makes use of Standard Changes and automation to meet user requests more efficiently.

116
Q

In much the same way that Event Management supports the Incident Management process by addressing incidents before they impact users, ___ ___ ___ can reduce the load on the Incident Management process by providing a means of addressing non-incident related requests before they enter the Incident Management stream.

A

In much the same way that Event Management supports the Incident Management process by addressing incidents before they impact users, Service Request Fulfillment can reduce the load on the Incident Management process by providing a means of addressing non-incident related requests before they enter the Incident Management stream.

117
Q

What is the purpose of the Access Management process

A

The Access Management process is charged with is providing authorized parties with appropriate access to service and information as specified in the Information Security Policy. Access Management executes the Information Security Policy as defined by the Information Security Management process, but does not itself set policy.

118
Q

Overview of Continual Service Improvement

A

Continual Service Improvement is about the alignment and re-alignment of services, processes, functions, etc. with changing business needs. It is also concerned with the consistent application of quality management methods to the overall Service Management effort.

119
Q

What business value does Continual Service Improvement offer to the Service Provider and customer organizations

A
  • Ensuring that services, processes, and other aspects of the Service Management effort are aligned with business objectives
  • Ensuring that services meet agreed levels of performance
  • Ensuring that the efficiency (cost) of service delivery improves steadily
  • Ensuring that all aspects of the Service Management effort undergo regular and consistent reviews
120
Q

Measurement plays a critical role within ITIL®, both as a part of Continual Service Improvement, but also within Service Level Management and as an essential part of all processes. Measurements can be used for four basic purposes as shown below:

A
  • To JUSTIFY a proposed course of action
  • To DIRECT activity
  • To INTERVENE when corrective action is required
  • To VALIDATE actions which have already been taken
121
Q

Measurements are the end result of a hierarchy of activities which link measurements to business objectives

Objectives

Critical Success Factors

Key Performance Indicators

Metrics

Measurements

A
  • Objectives establish the reason for measurement. Measurement in itself has no value. Rather, it only has value inasmuch as it supports achievement of specific objectives
  • Critical Success Factors define specific things that must happen if objectives are to be achieved
  • Key Performance Indicators are metrics which specifically indicate progress or performance around or toward Critical Success Factors
  • Metrics are the definitions of what will be measured and how it will be measured
  • Measurements are the actual readings taken based upon a specific metric.
122
Q

What is the Deming Cycle

A

The Deming Cycle is an improvement model originally created by W. Edwards Deming and used to great success in the Japanese auto industry. It consists of four simple steps (Plan, Do, Check, Act)

123
Q

What is the Continual Service Improvement Model

A

a simple set of guiding questions which can be used to organize and perpetuate an improvement program. It closely mirrors the basic approach also used in the ITIL 7 - Step Improvement Process

  • What is the vision?
  • Where are we now?
  • Where do we want to be?
  • How do we get there?
  • Did we get there?
  • How do we maintain momentum

The Seven Step Improvement Process provides a simple means of using measurement to guide the improvement and correction of service performance. The steps are:

A
  • Decide what should be measured
  • Decide what can be measured
  • Gather the data
  • Process the data
  • Analyze the data
  • Present and use the data
  • Implement corrective action
126
Q

What activities and objectives do Service Level Management and Continual Service Improvement share?

A

Both Service Level Management and Continual Service Improvement emphasize regular measurement and review of services and other aspects of the Service Management effort.

127
Q

In the most fundamental sense, automation and technology play an important role in IT Service Management by helping human decision makers effectively confront vastly more complex scenarios than they might otherwise be able to. Some examples include:

A
  • Use of automation to identify patterns and trends in large data sets such as event logs, incident logs, etc.
  • Use of automation to help guarantee consistency during design efforts
  • Use of automation to accurately record high volumes of detailed data, e.g. incident logs
  • Use of automation to avoid arbitrary assignment of priority to incidents, problems, changes, etc.
  • Use of automation to respond to events in real time

ITIL® urges the point that all phases of the Service Lifecycle can be supported very effectively using technology and automation.

128
Q

ITIL® offers some discussion of how automation can best be used to support processes. It’s most essential recommendations include:
