Who should the Source Inspector notify if they believe that product quality may be compromised...

The correct answer isB. The inspection coordinator. In the API source inspection framework, the inspector’s role is to independently observe, verify, document, and communicate quality-related concerns through the established inspection reporting chain. When schedule pressure appears likely to compromise product quality, the issue must be escalated to theinspection coordinator, because that person manages inspection execution, communication flow, and coordination between the purchaser, supplier, and inspection function. This keeps the inspector independent and ensures the concern is addressed formally rather than informally.

The other options are less appropriate. TheMaster Scheduleris responsible for planning and timing, not for controlling inspection escalation. Theshop QA Managerbelongs to the supplier’s organization, so reporting directly there could weaken the inspector’s independent reporting path. TheProject Managermay ultimately need awareness, but the normal and correct first notification route in source inspection administration is through the inspection coordinator. This approach aligns with API source inspection practice, where quality threats, deviations, and risks are communicated through designated inspection channels so that corrective action, hold points, and surveillance priorities can be managed properly.
