To simplify this part of the homework assignment, we will pretend that FabTex uses only

one supplier, Mighty Textiles, for garments and patches; and only one subcontractor, Xavier

Sewing.

FabTex Corporation sells customized shirts and work uniforms.

Once a sales order has been taken from a customer, FabTex purchases the required apparel items

and patches from one or more manufacturers. Often, a garment must be embroidered or have a

patch sewn on. FabTex does not do this work in house but instead contracts with three small

firms located in Puerto Rico where labor costs are much lower than in Detroit. Until they are

delivered to customers, garments and patches are always the property of FabTex, whether they

are in the Detroit location, in transit to or from a subcontractor, or in the hands of a subcontractor.

For an embroidered garment or when a patch is to be attached, the subcontractor furnishes the

thread. Three basic scenarios will clarify the situation. In scenario one, all items except thread

have been shipped to FabTex. FabTex ships the garments and possibly patches to the

subcontractor for processing. In scenario two, the manufacturer ships all items directly to the

subcontractor. In scenario three, some items have been shipped to FabTex and the remaining

items have been shipped directly to the subcontractor. Whenever goods are shipped directly to a

subcontractor, the manufacturer sends a notification to FabTexs purchasing agent. When goods

are received from a manufacturer or a subcontractor, FebTexs warehouse supervisor records the

receipt. When goods are shipped to a subcontractor or to a customer, the warehouse supervisor

records the shipment.

Subcontractors ship completed garments to FabTex. When a shipment is made, the subcontractor

sends a notification to FabTexs purchasing agent. Each shipping notification mentioned above

contains the shipping date, the vendors (manufacturer or subcontractor) name, the address to

which the goods are being shipped, FabTexs sales order number; and for each item being

shipped, FabTexs inventory part number and the quantity shipped.

FabTex has difficulty tracking garments and patches that have been sent to a subcontractor. It

plans to record all transactions related to goods sent to and received from subcontractors on a

Hyperledger Fabric blockchain. FabTex expects to record other transactions on this blockchain

as well, but the details of those transactions are beyond the scope of this homework assignment.

For each of the blanks, which one of the following terms fits best? Use each term exactly

one time. In your Word document, copy and paste the above nine questions exactly as written

and use the correct term below in place of each blank. Note that question three contains

two blanks.

1. FabTex, Mighty, and Xavier each has a(n) ________ to authorize which of their

employees can use the blockchain.

2. A(n) ________ has been created on the Hyperledger Fabric network to keep transactions

among FabTex, Mighty, and Xavier confidential.

3. A(n) ________ was used to install on the blockchain the ________ that will process

transactions among the three companies.

4. Mandy, a sales representative at Mighty, prepares a notification to Fred, a purchasing

agent at FabTex stating that ten dozen blue polo shirts for FabTexs customer Henrys

Auto Parts have been shipped to Xavier for embroidering. Mandy and Fred each has a(n)

________ on HyperLedger Fabric.

5. Mark, the sales manager at Mighty, and Felice, the purchasing director at FabTex, both

authorize Mandys notification. Mark and Felice each as a(n) ________ on HyperLedger

Fabric.

6. On Hyperledger Fabric, Mandys authorized transaction is processed by a(n) ________.

7. There must be at least one ________ on the Hyperledger Fabric network that adds

Mandys authorized transaction to a block.

8. The Hyperledger Fabric blockchain is also known as the ________.

9. Xavier embroiders three dozen of the blue polo shirts and ships them to FabTex. The

________ could be used to store the balance (seven dozen in this example) of shirts

remaining at Xaviers facility.

In a single paragraph, evaluate FabTexs use of a Hyperledger Fabric

blockchain for this application of tracking goods sent to and received from subcontractors. What

benefits could FabTex obtain? Are there any drawbacks to using a Hyperledger Fabric

blockchain for this purpose?
