DevOps enhances service management by promoting the principle of "shifting left." This involves integrating operational and service management concerns (such as quality assurance, security, and supportability) earlier in the development pipeline. By doing so, potential issues are identified and addressed sooner, breaking down traditional silos between development and operations teams. This early and continuous collaboration, supported by automation, results in faster feedback loops, higher quality releases, and leaner, more efficient end-to-end service delivery processes, which is a core goal of the VeriSM approach.

A. DevOps is a set of practices and a cultural movement that integrates with service management frameworks; it is not the foundational framework itself.

C. DevOps is applicable to the entire lifecycle of both new and existing services, focusing on continuous improvement, not just initial development.

D. While a more recent movement, DevOps directly and significantly contributes to the evolution and advancement of traditional service management practices.

Section 3.4.3, DevOps, Page 58: This section describes DevOps as a movement that "stresses communication, collaboration and integration between software developers and IT operations professionals." This integration is the mechanism for "shifting left." The text also mentions applying "lean principles," which directly supports the idea of creating "leaner and more efficient processes."

Section 3.2, The VeriSM™ model, Page 45: The VeriSM Management Mesh is shown to incorporate various practices, including DevOps, demonstrating that DevOps is an enhancing component within a broader service management approach, not the foundation (refuting option A).
