Example: A CMDB stores information about all the servers, applications, and network devices in an organization, along with their relationships and dependencies.
Baseline
A Baseline is a snapshot of the configuration of a CI at a specific point in time. It provides a reference point for future changes and audits.
Example: A Baseline for a software application might include the version number, configuration settings, and dependencies at the time of deployment.
Change Management
Change Management is the process of managing changes to CIs in a controlled and systematic manner. It ensures that changes are properly assessed, approved, and implemented.
Example: A Change Management process ensures that any updates to a server are documented, tested, and approved before being implemented.
Version Control
Version Control is the practice of tracking and managing changes to software code and other configuration items. It ensures that different versions of a CI can be managed and restored if necessary.
Example: A version control system tracks changes to a software application's code, allowing developers to revert to previous versions if needed.
Impact Analysis
Impact Analysis is the process of evaluating the potential effects of a change on the IT environment. It helps in determining the risks and benefits of a change.
Example: Before implementing a new software update, an Impact Analysis is conducted to assess its effects on other systems and services.
Configuration Identification
Configuration Identification is the process of identifying and documenting CIs and their attributes. It ensures that all CIs are properly identified and categorized.
Example: Configuration Identification involves creating a list of all hardware and software components in an IT environment, along with their specifications.
Configuration Control
Configuration Control is the process of managing changes to CIs in a controlled manner. It ensures that only authorized changes are made and that all changes are documented.
Example: Configuration Control involves setting up a process for approving and implementing changes to a server, ensuring that all changes are logged and tracked.
Configuration Status Accounting
Configuration Status Accounting is the process of recording and reporting the status of CIs. It provides information on the current state of each CI.
Example: Configuration Status Accounting involves maintaining a record of all changes made to a software application, including who made the changes and when they were made.
Configuration Verification and Audit
Configuration Verification and Audit is the process of verifying that CIs are configured according to the organization's standards and policies. It ensures compliance and identifies any discrepancies.
Example: A Configuration Audit involves checking that all servers in an IT environment are configured according to the organization's security policies.
Service Asset and Configuration Management (SACM)
Service Asset and Configuration Management (SACM) is the process of managing the assets and CIs that are required to deliver IT services. It ensures that all assets and CIs are properly managed and maintained.
Example: SACM involves managing all hardware, software, and documentation required to deliver IT services, ensuring that they are properly maintained and updated.
Configuration Management System (CMS)
A Configuration Management System (CMS) is a set of tools, processes, and procedures used to manage the configuration of IT services and infrastructure. It supports the CM process.
Example: A CMS includes tools for tracking CIs, managing changes, and generating reports on the status of IT services.
Configuration Management Plan
A Configuration Management Plan (CMP) is a document that outlines the strategy, processes, and procedures for managing the configuration of IT services and infrastructure. It provides a roadmap for implementing CM.
Example: A CMP includes details on how CIs will be identified, documented, and managed, as well as the roles and responsibilities for CM activities.
Configuration Management Tools
Configuration Management Tools are software applications used to support the CM process. They help in tracking CIs, managing changes, and generating reports.
Example: Tools like ServiceNow, BMC Remedy, and IBM Maximo are commonly used for managing CIs and supporting the CM process.
Configuration Management Roles
Configuration Management Roles define the responsibilities and duties of individuals involved in the CM process. These roles ensure that CM activities are properly executed.
Example: Roles in CM might include Configuration Manager, Change Manager, and Configuration Auditor, each with specific responsibilities for managing CIs.
Configuration Management Metrics
Configuration Management Metrics are key performance indicators (KPIs) used to measure the effectiveness of the CM process. They help in assessing the quality and efficiency of CM activities.
Example: Metrics might include the number of CIs managed, the time taken to implement changes, and the accuracy of CMDB data.
Configuration Management Process
The Configuration Management Process is a series of steps and activities designed to manage the configuration of IT services and infrastructure. It ensures that all CIs are properly identified, documented, and managed.
Example: The CM Process includes steps such as Configuration Identification, Configuration Control, and Configuration Status Accounting.
Configuration Management Governance
Configuration Management Governance involves establishing policies, procedures, and standards for managing the configuration of IT services and infrastructure. It ensures that CM activities are aligned with organizational goals.
Example: Governance in CM involves setting up policies for change management, version control, and configuration auditing, ensuring that they are followed across the organization.
Configuration Management Integration
Configuration Management Integration is the process of integrating CM activities with other IT processes, such as Change Management, Incident Management, and Problem Management. It ensures that CM supports the overall IT service management strategy.
Example: CM Integration involves ensuring that changes to CIs are properly documented and tracked in the CMDB, and that any incidents or problems related to CIs are resolved in a timely manner.
