An increase in the percentage of returned goods for consumer products is most closely associated with end-user dissatisfaction. When customers return products, it typically indicates that their expectations were not met. This dissatisfaction can stem from various factors, such as the product not functioning as intended, quality concerns, or a mismatch between the product and the consumer's expectations based on marketing or previous experiences.

Understanding end-user dissatisfaction is crucial because it highlights a gap in quality or service that needs to be addressed. By analyzing the reasons behind returns, organizations can identify specific issues that may contribute to a lack of customer satisfaction. This can lead to improvements in product design, manufacturing processes, customer service, or packaging to enhance customer experience and reduce return rates.

Meanwhile, while the other choices reflect important concepts within quality management and Six Sigma, they do not directly correlate to the primary reason for an increase in returned goods. Issues like product specifications, internal reject rates, and nonconforming material costs can contribute to the broader picture of product quality but are not as directly tied to the end-user's perception and experience, which drives return behavior.
