According to PeopleCert DevOps Foundation v3.6, the five primary values that guide successful DevOps adoption are summarized in theCALMSframework:Culture, Automation, Lean, Measurement, and Sharing.
* Culturefocuses on breaking down silos, encouraging trust, and promoting collaboration between development, operations, security, QA, and business teams.
* Automationis essential for speeding up delivery, reducing manual errors, and ensuring repeatability across the software delivery lifecycle.
* Leanemphasizes the elimination of waste, limiting work in progress (WIP), and improving flow.
* Measurementmeans using metrics and data to inform decisions, identify bottlenecks, and drive continuous improvement.
* Sharingfosters transparency, knowledge transfer, and a unified approach to goals and problem-solving.
Option A replaces automation and lean principles with softer collaboration aspects, which are important but not recognized as the formal value set. Option C replaces "Measurement" with "Metrics," which is only a part of measurement. Option D substitutes "Accountability" for "Automation," which is not part of the CALMS model.
Therefore, the official correct set of values per the DevOps Foundation syllabus isB.
