How does continuous delivery positively impact change control processes?

Continuous Delivery (CD) positively impacts change control by integrating risk assessment and validation directly into the software delivery pipeline. The core mechanism for this is the extensive use of automated testing facilities. These automated tests provide immediate, consistent, and reliable evidence that a new build is of high quality and low risk. This evidence can be used to automate the approval of standard changes, bypassing the need for a manual Change Advisory Board (CAB) review. This makes the change process significantly faster and more efficient while maintaining rigorous, evidence-based control, shifting the focus from manual approval to automated verification.

A. Continuous Delivery fundamentally redefines traditional change management, shifting it from a manual gate to an automated, integrated process.
C. This is too vague. The specific, actionable information from automated test results is the key impact, not just an undefined increase in information.
D. Continuous Delivery does not imply less rigor. Instead, it applies rigor continuously through automated checks and balances within the pipeline.

Section 4.3.2, "The impact of DevOps on service management practices," discusses how practices like continuous delivery, supported by automation, lead to the evolution of traditional processes like change management into more streamlined, automated functions.

This paper explains that in DevOps (of which CD is a key practice), "Automated testing and quality assurance are integrated into the continuous delivery pipeline," which serves as the basis for transforming traditional, slow change control into a rapid, automated verification process.
