According to PeopleCert DevOps Foundation v3.6, theSecond Wayof DevOps focuses on creating and amplifyingfeedback loops. The primary purpose of shortening these loops is toaccelerate the flow of work and informationbetween all stages of the delivery pipeline, especially between Development and Operations.
When feedback loops are short, defects, performance issues, and risks can be identified and resolved earlier in the process, preventing costly delays and large-scale rework. This supportsfaster, safer releasesand improves the organization’s responsiveness to customer needs.
WhileA(learning) andD(knowledge sharing) are important benefits of feedback loops, they aresecondaryoutcomes. The main, direct effect is improvingflow efficiency—ensuring that handoffs between Dev and Ops happen smoothly, quickly, and with higher quality.
OptionC(value stream mapping) is a useful Lean practice to identify delays and bottlenecks, but it is adiagnostic tool, not the primary improvement gained from shortening feedback loops.
Thus, the correct answer isB—shortened feedback loops primarily improve IT performance by ensuringfaster flowbetween Development and Operations.
