Which integration approach assembles system elements by subsets, and the subsets are assembled together?

• A. Verification Process
• B. Subset integration
• C. Inspection
• D. Analysis

Answer: (B)

Subset integration focuses on building the system by grouping elements into smaller subsets, integrating each subset, and then bringing the subsets together to form the complete system. This approach helps manage complexity by isolating interfaces within each subset and allowing parallel work, while also enabling early testing of how those subsets interact when they are combined. Verification, by contrast, is about ensuring the final product meets requirements through tests and reviews, not about the way the system is assembled. Inspection is a formal examination of artifacts for defects, not an integration method. Analysis involves evaluating properties or behavior through models or calculations, rather than assembling hardware or software components. Therefore, assembling system elements by subsets and then integrating those subsets best matches subset integration.
