Best practices for IT change management

1. Change Management Policy and Framework: Establish a clear policy for change management that details the scope, objectives, and underlying principles. This framework will be the foundation upon which all change management processes and procedures are based.
2. Roles and Responsibilities: Clearly define roles and responsibilities including:

• Change initiator/requestor
• Change manager/coordinator
• Change advisory board (CAB)
• Change implementer
• Change reviewer

1. Change Classification:

• Standard Changes: Pre-approved, low risk, and recurring.
• Normal Changes: Require review and approval.
• Emergency Changes: Must be implemented as soon as possible, often due to critical incidents.

1. Change Prioritization: Rank changes based on business importance and urgency. This will ensure that high-impact changes are addressed appropriately.
2. Change Advisory Board (CAB): Establish a CAB to review, prioritize, and approve or reject normal changes. The CAB should be composed of individuals from various IT areas and potentially key business stakeholders.
3. Risk Assessment: Before implementing any change, evaluate the risks associated. Consider potential negative impacts on the IT environment and business operations.
4. Testing: Ensure that all changes are tested in a controlled environment that mirrors the production environment as closely as possible.
5. Communication: Inform relevant stakeholders about upcoming changes, the reasons for those changes, and any potential impacts. Communication should be clear, timely, and consistent.
6. Implementation: Ensure changes are implemented during defined change windows to minimize disruptions. Have a back-out plan ready in case the change doesn't go as expected.
7. Documentation: Maintain a record of all changes, their reasons, the persons involved, date and time, and any outcomes (including failures).
8. Post-Implementation Review (PIR): After the change is implemented, review its success and any unintended consequences. This is an opportunity to learn and improve the change management process.
9. Audit & Review: Periodically review the change management process to ensure compliance with organizational policies and objectives. Look for opportunities to improve efficiency and effectiveness.
10. Feedback Mechanism: Have a method for stakeholders to provide feedback on the change management process, and use this feedback to make continuous improvements.
11. Integration with Other ITSM Processes: Ensure that change management is tightly integrated with other ITSM processes such as incident management, problem management, configuration management, and release management.
12. Tools: Utilize ITSM tools to automate and streamline the change management process. This can include tools for logging change requests, conducting impact analyses, scheduling changes, and tracking change histories.
13. Continuous Improvement: Always look for opportunities to enhance the change management process. Leverage metrics, feedback, and lessons learned from past changes to drive improvement.
