MIL-Q9858A standard is used to ensure quality in software development.

• A. MIL-Q9858A
• B. ISO 9001
• C. MIL-STD-491
• D. CMMI

Answer: (A)

MIL-Q9858A sets the DoD’s quality program requirements for suppliers, ensuring that work—whether hardware or software—meets contract specifications through defined QA activities, documentation, audits, and corrective actions. In defense software development, the quality program elements described by this standard provide the structured controls needed to verify that software deliverables satisfy requirements and are produced under disciplined processes. ISO 9001 is a general quality management system not specific to DoD software programs, CMMI is a software process improvement model rather than a DoD QA program, and MIL-Q-9858A is the standard that establishes the DoD’s formal quality program framework for contractors, including software development.
