Which type of decision-making process involves a thorough search before making a purchase?

The type of decision-making process that involves a thorough search before making a purchase is extended problem-solving. This process typically occurs when the consumer faces a high level of involvement in the purchase decision, often due to factors such as high cost, significant risk, or a strong personal relevance of the product. During extended problem-solving, consumers engage in comprehensive research, exploring various alternatives, gathering information, and evaluating options in depth before reaching a decision. This is particularly true for big-ticket items or purchases that are infrequent and therefore require more thought and consideration.

In contrast, routine problem-solving involves little to no deliberation, as consumers make choices based on habitual purchasing behavior or brand loyalty, often for low-involvement items. Limited problem-solving falls between the two extremes, where some deliberation and information gathering may occur but is less extensive than in extended problem-solving, suitable for moderately priced products where consumers are familiar with their options but still wish to weigh alternatives.
