Which elements are incorporated into SOPs for supplier qualification?

• A. Acceptance testing requirements only.
• B. Supplier selection criteria, performance monitoring, and acceptance testing requirements.
• C. Supplier selection criteria only.
• D. Performance monitoring only.

Answer: (B)

Supplier qualification SOPs are meant to govern the entire process of working with vendors, from how you choose them to how you verify and monitor their performance over time. The best choice includes supplier selection criteria, the requirements for acceptance testing, and the plan for ongoing performance monitoring. This combination ensures you pick capable suppliers, confirm that delivered goods or services meet your specifications before you accept them, and continuously track performance to catch issues early and drive improvements. Limiting the SOP to only one aspect leaves gaps: selecting a supplier without a plan for testing may lead to unverified quality; testing alone misses how you evaluate and maintain a capable supplier; monitoring alone lacks upfront criteria and testing to ensure initial conformance.
