Detailed Explanation:

The correct answer is B. Evaluate the impact of the defect on the final product.

When a supplier component defect is discovered, the first step should be to determine the significance and impact of that defect. Before deciding whether to notify the supplier, inform purchasing, or impose 100% inspection, the organization needs to understand:

how the defect affects fit, form, or function,

whether product safety or performance is at risk,

whether current inventory or shipped product may be affected,

and how urgent the response must be.

This evaluation provides the basis for proportionate action. Without assessing impact first, the organization may overreact, underreact, or choose the wrong containment method.

Why the other options are incorrect:

A. Order 100% inspection on all of the components from that supplier

This may be necessary later, but it is premature without first understanding the seriousness and scope of the defect.

C. Notify purchasing of the defect

Purchasing should usually be informed, but not before the defect impact is assessed.

D. Notify the supplier of the defect

The supplier should be notified, but the organization first needs enough technical understanding of the issue to communicate the problem accurately and determine urgency.
