Circle has a "slider" configuration item with four positions: nothing, some things, most

things, and everything


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

changes (fixes) – all with a minimum risk to IT infrastructure.


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

a mirror set.


Software configuration management - Purposes

1 Configuration identification - Identifying configurations, configuration items and baselines.


Dual Vee Model - Vee Model

1 Lowest Configuration Item)


Dual Vee Model - The Entity Vee Model

1 An Entity Vee (figure - below) exists for every entity of the architecture from the system,

down to the lowest configuration items (LCIs), such as computer software units or hardware

components


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 - Overview

1 The CM process for both hardware and software configuration items comprises five distinct disciplines as established in the MIL–

HDBK–61A and ANSI/EIA-649.



1 CI incrementally establishes and maintains the definitive current basis for Configuration

Status Accounting (CSA) of a system and its configuration items (CIs) throughout their

lifecycle (development, production, deployment, and operational support) until

disposal.



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.


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.



1 *Configuration change control is a set of processes and approval stages required to

change a configuration item's attributes and to re-baseline them.



1 *Configuration status accounting is the ability to record and report on the configuration

baselines associated with each configuration item at any moment of time.



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.

Quality function deployment - House of Quality

1 In addition, the same technique can extend the method into the constituent product

subsystems, configuration items, assemblies, and parts. From these detail level

components, fabrication and assembly process QFD charts can be developed to

support statistical process control techniques.


ITIL security management - Implementation

1 ImplementClassifying and managing of IT applications Process of formally grouping configuration items by type, e.g., software, hardware, documentation, environment,

application.


Incident management - Incident management process, as defined by ITIL

1 Failure of a Configuration Item that has not yet impacted Service is also an Incident


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')


Change management (ITSM) - Information Technology Infrastructure Library

1 * results in a new status of one or more configuration items (CIs)


ITIL - Change management

1 Change management aims to ensure that standardised methods and procedures are used for efficient handling of all changes. A

change is an event that results in a new status of one or more configuration items (CIs), and which is approved by management, is cost-

effective, enhances business process changes (fixes) – all with a minimum risk to IT

infrastructure.


ITIL - 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

a mirror set.


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.


Business Service Management - BSM Technology Tools

1 BSM allows IT departments to operate by service rather than by individual configuration

items or technology silo, enabling prioritization of efforts, ultimately improving

the service that is delivered to the business or organization.


Configuration management database

1 Its contents is intended to hold a collection of IT assets that are commonly referred to as

Configuration Items (CIs), as well as descriptive relationships between such assets


Configuration management database

1 The CMDB records configuration items (CI) and details about the important attributes and

relationships between CIs. Configuration managers usually describe CIs using three

configurable attributes:


Configuration item

1 The term 'configuration item' or 'CI' refers to the fundamental structural unit of a

configuration management system


Configuration item - Role in configuration management

1 The term configuration item can be applied to anything designated for the application of the elements of configuration management and treated as a single entity in the configuration

management system.



1 *The entity must be uniquely identified so that it can be distinguished from all other

configuration items.



1 *From the perspective of the implementer of a change request|change, the CI is the what of the change. Altering a specific baseline

(configuration management)|baseline version of a configuration item creates a new version

of the same configuration item, itself a baseline. In examining the effect of a change, two of the questions that must be asked are:



1 :# What configuration items are affected?



1 :# How have the configuration items been affected?



1 A Software release|release (itself a versioned entity) may consist of several configuration

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.



1 It should be defined at a level such that an individual involved with product marketing

and an individual at the coalface of implementation can agree to a common

definition when they use the name of the lection and identification of configuration

items for a particular project can be seen as the first step in developing an overall

architecture#See_also|architecture of the product from the top down.



1 Configuration items, their versions, and their changes form the basis of any configuration audit.


Definitive Media Library

1 The Definitive Media Library provides the storage area for software objects ready for

deployment and should only contain master copies of controlled software media

Configuration item|Configuration Items (CIs) that have passed appropriate quality

assurance checks, typically including both procured and bespoke application and gold

build source code and executables


Event Management (ITIL)

1 An 'event' can be defined as any detectable or discernible occurrence that has significance for the management of the IT Infrastructure

or the delivery of IT service and evaluation of the impact a deviation might cause to the services. Events are typically notifications

created by an IT service, Configuration item|Configuration Item (CI) or monitoring tool.


Event Management (ITIL) - Purpose/Scope

1 * Event Management can be applied to any aspects of Service management|Service

Management that can be controlled and can be automated (Configuration Items)


Event Management (ITIL) - Event Notification and Detection

1 Event notifications can be proprietary, only certain management tools can be used to detect events. Most of the Configuration

item|Configuration Items (CIs) generate event notifications using SNMP open protocol

(Simple Network Management Protocol).


Definitive software library

1 A 'definitive software library' ('DSL') is a secure location, consisting of physical media or a

software repository located on a network file server, in which the definitive authorized

versions of all software configuration items (CIs) are stored and protected


Structure chart - Overview

1 An accurate and complete structure chart is the key to the determination of the

configuration items, and a visual representation of the configuration system

and the internal interfaces among its CIs(define CI clearly)



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.



1 CI incrementally establishes and maintains the definitive current basis for Configuration

Status Accounting (CSA) of a system and its configuration items (CIs) throughout their

lifecycle (development, production, deployment, and operational support) until

disposal.



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.


Configuration 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.


IBM Rational ClearCase - Views

1 This was a departure from the repository / sandbox model, allowing for the early

management of artifacts (before they are checked in, and not limited to these first order

configuration items).


Configuration Management (ITSM)

1 Configuration Management (CM) is an 'Information Technology Infrastructure

Library' (ITIL) version 2 and an IT Service Management (ITSM) 'process' that tracks all of

the individual Configuration Items (CI) in an information system|IT system which may be

as simple as a single server (computing)|server, or as complex as the entire IT

department


Configuration Management (ITSM) - Configuration item

1 A Configuration item (CI) is an IT asset or a combination of IT assets that may depend on

and/or have relationships with other IT processes. A CI will have attributes which may be hierarchical and relationships that will be assigned by the configuration manager in the

CM database.


Juju (software) - Juju's Stengths and Weaknesses

1 By creating a relationship between for instance MySQL and Wordpress, MySQL will

share with Wordpress any IPs, user, password and other configuration items


Baseline (configuration management)

1 In a similar manner, associating multiple configuration items with such a baseline indicates those items as being approved.


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


Physical configuration audit

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
