A decade ago, DevOps teams struggled with slow operations and manual review processes, but today's teams have shifted toward Agile workflows and automation, making change management a crucial component of their success. The 2020 State of DevOps Report identifies four distinct styles of change management, with engineering-focused approaches leveraging automation for rapid deployment cycles and operationally mature teams balancing rapid changes with regulatory requirements. However, ad hoc and governance-focused methods suffer from inefficiency and low morale due to minimal automation and heavy reliance on manual processes. Toil, or repetitive and low-value work, plagues teams with inadequate automation, but smart use of automation platforms like Puppet and Chef can minimize toil and enhance DevOps efficiency. Despite the importance of automation, employee involvement remains critical, as organizations that engage their teams effectively are significantly more successful in change management. The report emphasizes that embracing automation and maintaining strong team communication are central to achieving effective DevOps change management.
