What is Change Management?

Change management controls are among the most scrutinized areas in SOC 2 audits because unauthorized or poorly managed changes are a leading cause of system outages and security incidents. A mature change management process includes change request documentation, risk and impact assessment, peer review (especially for code changes), approval by appropriate stakeholders, testing in non-production environments, rollback planning, implementation with monitoring, and post-implementation review. In modern DevOps environments, change management is often implemented through pull request workflows with required code reviews, CI/CD pipelines with automated testing gates, and infrastructure-as-code with version control. SOC 2 auditors verify that all production changes follow the documented process by sampling change tickets and correlating them with deployment logs. ISO 27001 addresses change management through its operational planning and control requirements. The key is balancing control rigor with development velocity — overly bureaucratic processes lead to workarounds that create more risk than they prevent.
