A Gap Analysis for ISO/TS 22002-100 and 22002-1 involves reviewing each clause of the standards, comparing them with current practices, identifying compliance gaps, and developing an action plan with responsibilities and timelines. It focuses on common prerequisite program elements (like management, supplier control, and performance monitoring) and food manufacturing requirements (facility design, utilities, sanitation, pest control, and personnel hygiene). The outcome is a clear roadmap to align the existing system with the new ISO/TS requirements.
