$1.$ Using the Kraljic Supplier Segmentation framework, categorize the four products described in the case $($quartz sand, saw blades, copper sputtering equipment, face masks$).$ Provide a brief explanation for why you categorized each item the way you did.

a$.$ Quartz Sand$-$ Bottleneck

i$.$ It has a lower impact on profitability and it is a raw material used in large quantities in various industries. Its cost is not usually significant to the total cost of the end product.

c$.$ Copper Sputtering Equipment$-$ Strategic

i$.$ Copper sputtering equipment has a high impact on profitability. The performance and efficiency of this equipment can really affect production quality and costs.

d$.$ Face Masks$-$ Bottleneck

i$.$ They have a moderate impact on profitability while they may not be the most expensive component in the supply chain, they are critical for maintaining safety and meeting regulatory requirements.
