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

Show Suggested Answer Hide Answer
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.

I thought Tier two suppliers were also important, but I guess they might supply to Tier one instead? Not completely confident on this.

I practiced a similar question where Tier one was mentioned as the direct supplier. I feel like that’s the right answer here too.

I'm not really sure about this one. I remember something about different tiers, but I can't recall which one is direct.

I think it's Tier one suppliers since they are usually the ones that deal directly with the manufacturers.
