As network change accelerates across increasingly automated environments, network operators face growing challenges in maintaining visibility, control, and trust in network state. This eBook explores the role of change governance in reducing configuration drift, improving compliance and auditability, and creating a foundation for reliable automation and autonomous operations. It examines the risks of ungoverned change, the limitations of automation without governance, and how Blue Planet Configuration and Change Management helps operators make network changes visible, traceable, and validated across multi-vendor environments.
