Tailoring The Product

Merchandise that is generally similar in style or design, but may vary in such elements as size, price, and quality is collectively known as a product line. Most marketers believe that product lines must be closely correlated with consumer needs and wants.

Firms tend to change product items and lines after a period of time to gain a competitive advantage, to respond to changes in the economic climate, or to increase sales by encouraging consumers to buy a new model. For example, if the economy weakens, a manufacturer might use cheaper parts to make a product more affordable. Sometimes, however, manufacturers will alter the style rather than the quality of the item. Hemlines on dresses, for example, might go up or down, or the appearance or functionality of an automobile might be altered. The practice of changing the appearance of goods or introducing inferior parts or poor workmanship in order to motivate consumers to replace products is known as planned obsolescence. Some people object that this practice leads to waste or can be unethical. Manufacturers reply that consumers are conditioned to expect such changes and welcome the variety they offer, or they deny that poor quality was intentional.

The popularity of all products eventually wanes. In fact, successful products go through what is called a product life cycle, which describes the course of a product’s sales from its introduction and growth through maturity and decline. Some fad products such as Beanie Babies go through all four stages in a very short period. For others, such as phonograph records, the stages extend over decades.

Because products are always aging and sales of even the most successful products eventually decline, firms must continually develop and introduce new items. One study found that over 13,000 new products are introduced each year. But despite the millions of dollars that United States and Canadian companies invest in product research and consumer testing, it is estimated that more than 30 percent of new products fail at launch and 60 percent are never fully accepted by consumers and disappear after a few years. The high failure rate influences the pricing of successful products because profits from these products must help cover the development costs of products that fail.
