Information Technology Infrastructure Library - Change management
1 A change is an event that results in a new status of one or more configuration items
(CIs), and which is approved by management, cost-effective, enhances business process

Information Technology Infrastructure Library - Service asset and configuration management
1 Service asset and configuration management is primarily focused on maintaining
information (i.e., configurations) about Configuration Items (i.e., assets) required to
deliver an IT service, including their relationships.

Information Technology Infrastructure Library - Incident management
1 2007: An unplanned interruption to an IT service or a reduction in the quality of an IT service. Failure of a configuration item that
has not yet impacted service is also an incident. For example, failure of one disk from

Dual Vee Model - Phasing of decision gates
1 For simplicity of illustration, only one Entity Vee is shown intersecting the Architecture Vee at each decomposition level. Note that
the design-to sequence is top down, starting at the system level and proceeding consistent
with decomposition to the lowest configuration item level (LCI). This sequence
ensures that there is proper top down requirements flowdown and traceability.

Configuration management - Software
1 *Configuration identification is the process of identifying the attributes that define every aspect of a configuration item. A configuration item is a product (hardware and/or software) that has an end-user purpose. These attributes are recorded in configuration documentation and baselined.
Baseline (configuration management)|Baselining an attribute forces formal configuration change
control processes to be effected in the event that these attributes are changed.

Configuration management - Software
1 *Configuration audits are broken into functional and physical configuration audits. They occur
either at delivery or at the moment of effecting the change. A functional configuration audit
ensures that functional and performance attributes of a configuration item are achieved,
while a physical configuration audit ensures that a configuration item is installed in accordance with the requirements of its detailed design
documentation.

Change management (ITSM) - Information Technology Infrastructure Library
1 Change Management is a process used for managing the planned deployment of
alterations to all configuration items in the configuration management database, (or CIs in the CMDB) that are a part of a business's
live (production) and test (UAT) environments along with any other environment that a
business wants to have under Change Management - generally all environments that
are under the control of 'ICT Operations')

Incident management (ITSM) - Definition
1 :An unplanned interruption to an IT Service or a reduction in the Quality of an IT Service.
Failure of a Configuration Item that has not yet impacted Service is also an Incident. For example, Failure of one disk from a mirror set.. The stated ITIL objective is to restore
normal operations as quickly as possible with the least possible impact on either the
business or the user, at a cost-effective price.

items or technology silo, enabling prioritization of efforts, ultimately improving
the service that is delivered to the business or organization.

items. The set of changes to each configuration item will appear in the release notes, and the notes may contain specific headings for each
configuration item. A complex hardware configuration item may have many levels of
configuration items beneath its top level; each configuration item level must meet the same fundamental elements of the configuration
management system.

Baseline (configuration management) - Baselining Configuration Items
1 In the process of performing configuration management, configuration items (or work
products) may be assigned a baseline so as to establish them with a certain status

1 configuration item against its technical documentation to establish or verify the
configuration item's product baseline.

Physical configuration audit
1 The PCA is used to examine the actual configuration of the Configuration Item (CI)
that is representative of the product configuration in order to verify that the
related design documentation matches the design of the deliverable CI

Component repository management - Overview
1 The CM process for both hardware and software configuration items comprises five distinct disciplines as established in the [http://www.product-lifecycle-
management.com/download/MIL-HDBK-61B%20(Draft).pdf MIL–HDBK–61A] and
[http://webstore.ansi.org/RecordDetail.aspx?sku=ANSI%2FEIA-649-A+2004 ANSI/EIA-649]. These
disciplines are carried out as policies and procedures for establishing baselines and performing a standard
change management process.

Component repository management - Overview
1 * Configuration Status Accounting: Includes the process of recording and reporting configuration item descriptions (e.g.,
hardware, software, firmware, etc.) and all departures from the baseline during design
and production. In case of suspected problems, the verification of baseline
configuration and approved modifications can be quickly determined.

Component repository management - Configuration management database
1 CMDBs are used to track Configuration Items (CIs) and the dependencies between them,
where CIs represent the things in an enterprise that are worth tracking and managing, such as but not limited to
computers, software, software licenses, racks, network devices, storage, and even the
components within such items.
