This includes implementing processes and procedures to evaluate, approve, and implement changes in a controlled manner. Configuration control ensures that changes are managed with minimal disruption and risk to services.

Configuration Status Accounting

The objective is to capture and maintain accurate and up-to-date information about the status and attributes of CIs throughout their lifecycle. This information includes details such as version numbers, relationships, dependencies, and other relevant data that provide a comprehensive view of the configuration.

Configuration Verification and Audit

The objective is to regularly verify and audit the configuration data to ensure its accuracy, completeness, and compliance with defined standards and policies. Configuration audits help identify discrepancies, inconsistencies, or unauthorised changes within the configuration and facilitate corrective actions.

Configuration Reporting and Documentation

The objective is to generate and maintain documentation and reports related to the configuration of CIs. This includes creating configuration records, baseline documentation, and reports on configuration changes, status, and compliance. Configuration reporting and documentation support effective decision-making, communication, and compliance with organisational requirements.

Relationship Management

The objective is to establish and maintain accurate information about the relationships and dependencies between CIs. Understanding these relationships helps in assessing the impact of changes, diagnosing incidents and problems, and optimising service performance.

What Are the Components of Service Configuration Management?

Service Configuration Management aims to establish a reliable configuration management system (CMS) that provides a centralised repository for storing and managing configuration data. The CMS consists of tools, databases, and information that enable organisations to track and control the configuration items (CIs) that make up their IT infrastructure. Some key aspects of ITIL 4 Service Configuration Management include:

Configuration Management System (CMS)

The CMS is a set of tools, databases, and information that is used to manage configuration data. It provides a central repository for storing and maintaining configuration information, such as the relationships between CIs.

Configuration Item (CI)

A CI is a component of the IT infrastructure that needs to be managed and controlled. CIs can range from physical devices like servers and network switches to software applications, documents, and even people. Each CI is uniquely identified and has attributes that describe its characteristics.

Configuration Baseline

A configuration baseline represents the current and authorised configuration of a CI or a set of CIs. It serves as a reference point for future changes and helps ensure that the infrastructure can be restored to a known and stable state if needed.

Configuration Management Plan (CMP)

The CMP is a document that defines the policies, procedures, and responsibilities for implementing and managing SCM within an organisation. It outlines the activities, resources, and tools required to maintain the integrity of the configuration data.

Configuration Control

Configuration control involves establishing and maintaining control over changes to CIs. It includes processes for requesting, evaluating, approving, and implementing changes to the configuration. Change management and change evaluation processes are closely related to configuration control.

Configuration Audit

Configuration audits are conducted to verify the accuracy and completeness of configuration data. They help identify discrepancies, inconsistencies, or unauthorised changes and ensure that the CMS remains up to date and reliable.

Configuration Management Database (CMDB)

The CMDB is a fundamental component of the CMS. It is a database that stores configuration information, including CIs, their attributes, and relationships. The CMDB provides a single source of truth for configuration data and supports various IT service management processes.

What Activities Come Into Play?

ITIL 4 Service Configuration Management involves a range of activities to effectively manage and control the configuration of IT services, systems, and infrastructure components. These activities include:

Configuration Identification

This activity involves identifying and defining the Configuration Items (CIs) that make up the IT infrastructure. It includes establishing naming conventions, labelling, and assigning unique identifiers to each CI. The goal is to have a clear understanding of the components that need to be managed and controlled.

Configuration Control

Configuration control is the process of managing changes to the configuration of CIs. It includes activities such as assessing and evaluating proposed changes, obtaining approvals, and implementing changes in a controlled manner. Configuration control ensures that changes are managed with minimal disruption and risk to services.

Configuration Status Accounting

This activity involves maintaining accurate and up-to-date information about the status and attributes of CIs throughout their lifecycle. It includes recording information such as version numbers, relationships, dependencies, and other relevant data. Configuration status accounting provides a comprehensive view of the configuration at any given time. The key challenge is to ensure that the data in the CMDB reflects the status of the organization’s resources and that this status is correct (meaning there are no unauthorized changes).

Configuration Verification and Audit

This activity ensures that a new or changed IT service, process, plan, or other deliverable matches its design specification and is complete, accurate, and reliable. Verification and audit activities are conducted to validate the accuracy, completeness, and compliance of the configuration data. These activities involve comparing the actual configuration against the expected configuration, identifying discrepancies or inconsistencies, and conducting audits to ensure adherence to defined standards and policies. Verification and audit activities help maintain the reliability and integrity of the configuration data. Auditing is one of the tools of CMDB verification; a resource-demanding planned verification endeavour. It is usually organized and managed as a project and, like any project, should be justified and approved in order to occur. These audits are often combined with IT asset audits.

Configuration Baseline Management

A baseline configuration is the configuration of a product, service, or infrastructure that has been formally reviewed and agreed. It serves as the basis for further activities, such as use, development, and planning. Configuration baselines represent authorised and agreed-upon configurations of CIs at specific points in time. Baselines serve as reference points for managing changes and provide a known and stable state to which the infrastructure can be restored if needed. Baseline management involves creating, maintaining, and updating baselines as the configuration evolves.

Relationship Management

Relationship management focuses on understanding and managing the relationships and dependencies between CIs. It involves capturing and documenting the relationships to determine how changes to one CI can impact others. Relationship management helps assess the impact of changes, troubleshoot incidents and problems, and optimise service performance.

Configuration Reporting and Documentation

This activity involves generating and maintaining documentation and reports related to the configuration of CIs. It includes creating configuration records, documenting configuration changes, generating reports on configuration status, compliance, and performance. Configuration reporting and documentation support effective decision-making, communication, and compliance requirements.

These activities collectively form the core of ITIL 4 Service Configuration Management. By performing these activities effectively, organisations can ensure accurate configuration information, optimise change management, reduce risks, enhance incident and problem resolution, and support overall service quality and performance.
