Feedback loops are mechanisms that provide information to earlier stages in the process, enabling adjustments and improvements.
A: Dashboards provide real-time visibility into system health, deployment status, and other key metrics, allowing quick corrective action.
B: Monitoring and event data supply operational insights (latency, errors, resource utilization) that inform both Dev and Ops.
C: Peer review of changes allows early detection of issues before integration, improving code quality and reducing defects.
D—Product—isnota feedback mechanism. The product is the outcome of development and delivery; while customer feedback on a product can be part of a loop, the “product” itself is not the mechanism delivering actionable information upstream.
Thus,Dis the correct choice for “NOT” a feedback loop.
