WGU Operations Management (C215) Exam - Topic 4 Question 7 Discussion

Posted by Ailene on Apr 09, 2026 at 02:24 PM

Which tier-level supplier directly supplies materials or services to a processing and packaging plant?

Suggested Answer: A

Comprehensive and Detailed Explanation (250 words):

Tier one suppliers directly supply materials or services to a processing and packaging plant.

In supply chain hierarchy:

Tier one suppliers deliver components, raw materials, or services directly to the manufacturer

Tier two suppliers supply tier one

Tier three and beyond supply upstream tiers

JIT systems rely heavily on tier one suppliers because:

Delivery frequency is high

Quality must be consistent

Lead times must be short

Coordination must be tight

Operations Management stresses the importance of strong partnerships with tier one suppliers to ensure uninterrupted flow and minimal inventory.
