Which group has the most control over the planned obsolescence of a product?
- A.
Legislators
- B.
Manufacturers
- C.
Consumers
- D.
Designers
Correct Answer
B. ManufacturersExplanation
Manufacturers have the most control over the planned obsolescence of a product. Planned obsolescence refers to the practice of deliberately designing products with a limited lifespan or functionality, encouraging consumers to replace them sooner. Manufacturers have the power to determine the lifespan of a product by choosing the quality of materials, components, and production processes. They can also strategically release new models or updates to make older versions obsolete. While legislators can regulate certain aspects of product lifespan, ultimately it is the manufacturers who have the most influence over planned obsolescence. Consumers and designers may have some influence, but it is not as significant as that of manufacturers.Rate this question:
