In DevOps,culturerefers to the shared values, beliefs, and behaviors that influence how people work together. PeopleCert highlights culture as the foundation for collaboration, trust, and open communication—critical for breaking down silos and enabling continuous delivery.

OptionAbest captures this definition: culture reflects theway people think and behavein their daily work, including attitudes toward experimentation, problem-solving, and collaboration.

While team structure (B), automation strategy (C), and strategic direction (D) are important, they are outcomes or enablers that depend on the underlying culture. Without the right cultural foundation, DevOps practices and tools will not achieve their full potential.

DevSecOps is about integrating security into every stage of the software delivery lifecycle rather than treating it as a separate, post-development activity. PeopleCert DevOps Foundation v3.6 stresses that security mustshift left—moving testing, vulnerability scanning, and compliance checks earlier in the process.

Security as Codemeans embedding security policies, controls, and checks directly into infrastructure and application code. This includes:

Automated vulnerability scanning in CI/CD pipelines

Infrastructure-as-code with integrated security configurations

Policy-as-code to enforce compliance automatically

Static and dynamic application security testing (SAST/DAST) integrated into build pipelines

WhileAincorrectly says “shift right” (testing later in production), DevSecOps emphasizes shifting left.B(post-deployment audits) andC(external testing) can complement DevSecOps but don’t fully embed security into the delivery workflow.

Therefore,D – Security as codeis the most direct enabler of DevSecOps practices.

TheDeming Cycle (Plan-Do-Check-Act)is foundational to continuous improvement in Lean, and is specifically applied in theImprovement Katapractice:

Improvement Kata: A structured routine for continuous, incremental improvement based on scientific thinking (PDCA).

Value Stream Mapping and Andon cord are Lean practices, but they don’t directly reference PDCA as the core mechanism.

Extract-style reference:

“The Improvement Kata incorporates the Deming cycle (Plan-Do-Check-Act) to drive small, rapid cycles of change, helping teams to experiment, learn, and adjust.”

—Toyota Kata, Mike Rother

PeopleCert DevOps Foundation v3.6: Cites PDCA as integral to continuous improvement and Lean/DevOps adoption.

ChatOpsis the DevOps practice of using chat platforms (like Slack, Teams, Mattermost) as the central interface for communication, collaboration, and even automated deployment or support tasks.

It encourages “conversation-driven development, delivery, and support,” making processes transparent and collaborative.

Second Way(A) is about feedback loops, but not specifically conversational platforms.

Communication Platforms(C) is a generic term.

VisOps(D) is not a standard DevOps term.

Extract-style reference:

“ChatOps is a collaboration model that connects people, tools, process, and automation into a transparent workflow. Teams communicate and execute commands from a central chat client.”

—DevOps Handbook

PeopleCert Foundation v3.6: ChatOps promotes rapid feedback and a culture of sharing.
