Understanding IT change management: process, roles, and systems

Change is inevitable in IT environments, and managing it effectively is crucial for maintaining stable and efficient operations. IT change management is a structured process that ensures changes are made systematically and with minimal disruption. This article explores IT change management, its process, roles, systems, and the importance of documentation, providing a comprehensive overview for those seeking to understand and implement it effectively.

What is IT change management?

IT change management refers to the process, tools, and techniques used to manage changes in IT systems and services. Its primary goals are to minimize disruptions, improve service quality, and ensure that changes align with business objectives.

Goals and objectives of change management in IT

Ensuring changes are systematically planned and executed

The first objective is to make sure that every change is meticulously planned and executed according to a defined process. This means that changes are not made on an ad-hoc basis but follow a structured approach involving thorough planning, risk assessment, and scheduling. By doing so, we can foresee potential issues and have mitigation strategies in place, ensuring a smoother implementation.

Minimizing service disruptions and negative impacts

Another critical goal is to minimize any disruptions or negative impacts on IT services. This involves conducting comprehensive impact assessments before any change is approved, ensuring that the necessary precautions are taken to prevent service interruptions. The aim is to keep the IT environment as stable as possible, even during significant updates or modifications.

Enhancing service quality and performance

Improving the quality and performance of IT services is also a key objective. Through well-managed changes, we can introduce enhancements, fix bugs, and optimize performance, leading to a more reliable and efficient IT infrastructure. This continuous improvement helps in delivering better services to end-users and maintaining high levels of customer satisfaction.

Aligning IT services with business needs

Finally, ensuring that IT changes align with the broader business objectives is essential. This means that any proposed changes are evaluated not only for their technical merit but also for their strategic fit within the organization's goals. By doing so, IT can support the business effectively, enabling growth and innovation while maintaining operational stability.

Types of changes covered under IT change management

Standard changes: Pre-approved changes with low risk

Standard changes are routine, low-risk changes that follow a predefined process and do not require individual approval each time they are implemented. Examples include software updates or regular maintenance tasks. These changes are typically documented in a standard change catalog and can be executed quickly and efficiently since they have minimal impact on services.

Normal changes: Changes that require assessment and approval

Normal changes are those that need a thorough assessment and formal approval before they can be implemented. These changes might have a moderate impact on services and typically require more detailed planning and risk assessment. The change advisory board (CAB) usually reviews these changes to ensure they are justified and that any potential risks are adequately mitigated.

Emergency changes: Changes that need to be implemented urgently to resolve critical issues

Emergency changes are high-priority changes that need to be implemented immediately to address critical issues, such as security vulnerabilities or system outages. These changes bypass the regular approval process due to their urgent nature but are still documented and reviewed retrospectively. The goal is to resolve the issue as quickly as possible while minimizing any additional risks introduced by the rapid change.

The IT change management process

Managing changes in IT is crucial for keeping systems stable and making sure updates are beneficial. The process is structured into key stages, starting from the initial request and ending with a post-implementation review, ensuring every change is carefully evaluated, approved, and documented. Let's break down these stages to understand how they help achieve smooth and efficient transitions.

Identification and recording

All change requests are identified, documented, and logged in a central repository. This step ensures traceability and accountability.

Evaluation and planning

Change requests are assessed for potential impacts, risks, and resource requirements. A detailed plan is created to outline the steps for implementation.


A change advisory board (CAB) or designated authority reviews and approves or rejects the change requests based on their evaluation.


Approved changes are implemented according to the plan. This stage includes deploying updates, conducting tests, and communicating with stakeholders.

Review and closure

Post-implementation reviews are conducted to evaluate the change's success and address any issues. Successful changes are then formally closed.

Change management roles and responsibilities

According to a 2021 study conducted by Veeam, the biggest hurdle for digital change is a lack of skills and expertise. Effective change management involves several key roles, each with specific responsibilities. Here's an overview of these roles along with examples to illustrate their functions:

Change initiator

The person or team that identifies the need for a change and submits a change request.

Example: A network engineer notices recurring issues with the company's firewall settings and submits a request to update the firewall configuration to improve security and performance.

Change manager

Oversees the change management process, ensuring changes are planned, approved, and implemented effectively.

Example: The IT change manager reviews the firewall configuration change request, coordinates with the relevant teams, schedules the implementation, and monitors the progress to ensure it follows the approved plan.

Change advisory board (CAB)

A group of stakeholders that review and approve change requests, ensuring they align with business objectives and risk tolerance.

Example: The CAB, consisting of IT leaders, security experts, and business managers, meets to evaluate the proposed firewall update, considering its impact on operations and its alignment with the company's security policies.

Implementation team

Responsible for executing the change according to the approved plan, including testing and deployment.

Example: The [IT operations] ( receives the approved firewall update request, tests the new configuration in a staging environment, and then deploys it during a scheduled maintenance window.


Individuals or groups affected by the change. Their feedback and communication are crucial for successful change implementation.

Example: The stakeholders include the company's employees who use the network daily. They are informed about the upcoming firewall changes and provide feedback if they experience any issues post-implementation.

ITSM change management systems

When it comes to managing IT services, IT Service Management (ITSM) frameworks like ITIL are a game changer. They provide a structured approach that includes best practices for change management, ensuring that changes are handled smoothly and align with business objectives.

Benefits of using a change management system

  • Improved efficiency: A change management system automates the entire process, cutting down on manual work and reducing the chance of human error. This means change requests are processed faster and more consistently.
  • Enhanced visibility: With real-time tracking and reporting, everyone can see the status of change requests and follow their progress. This transparency helps pinpoint bottlenecks and ensures everyone is accountable.
  • Reduced risks: By standardizing how changes are assessed and approved, the system helps prevent unintended disruptions or conflicts. Thorough evaluations make sure that changes are safe and effective.

Key features to look for in a change management system
