Which statement about Vertical Integration is true?

Which statement about Vertical Integration is true?

• A. Across elements at a common hierarchy level
• B. Across external organizations
• C. Across hierarchy levels to satisfy higher-level expectations
• D. To reduce verification costs

Answer: (C)

Vertical integration means ensuring alignment and coherence across the different levels of the system hierarchy, so higher-level requirements and architecture drive what is done at the lower levels and the lower-level results reflect and satisfy those higher-level expectations. This connection from top to bottom helps maintain traceability, consistency, and verification evidence throughout the system design and development. So, why this statement fits best: it captures the essence of vertical integration—linking system-level goals to subsystem designs and components, and ensuring that decisions at the top are reflected in what’s built and tested below. It’s about maintaining a coherent thread from the upper system view down through detailed design and implementation. In contrast, horizontal integration would be across elements at the same level (subsystems or components at the same tier), external organization integration involves working with outside entities, and reducing verification costs is a potential benefit of effective integration but not what vertical integration is fundamentally about.
