Detailed Explanation:

The correct answer is C. Establish a system to verify that the supplier can meet the specified control criteria.

When a product requires environmental control, the most important issue during supplier qualification is whether the supplier can consistently meet the required environmental conditions and related specifications. The customer must therefore establish a method to verify that the supplier has the capability, controls, monitoring, and discipline necessary to satisfy those requirements.

This verification may include:

reviewing environmental control procedures,

evaluating monitoring and recording systems,

checking calibration and maintenance of control equipment,

assessing process capability,

and confirming ongoing compliance with specified criteria.

From a Quality Management Excellence perspective, this is a preventive, system-based action. The goal is not merely to detect problems after delivery, but to verify in advance that the supplier’s process can reliably produce conforming output under the required controlled conditions.

Why the other options are incorrect:

A. Obtain a liability waiver from the supplier

A liability waiver does not ensure product conformity. It is a legal or commercial measure, not a quality assurance control.

B. Ensure that the supplier uses a coding system for identifying and tracing all of its products

Traceability may be useful, but it does not by itself confirm that environmental control requirements are being met.

D. Implement an environmental safety system in the receiving area

Controls in the receiving area may protect material after delivery, but they do not verify that the supplier produced the product under the required environmental conditions.

Quality Management Excellence reference basis:

This answer aligns with Quality Management Excellence principles of:

supplier capability verification,

prevention over detection,

process control based on risk and requirements,

and ensuring that supplier systems can consistently meet specified conditions.
