The consumer buying process

The purchase process is initiated when a consumer becomes aware of a need. This awareness may come from an internal source such as hunger or an external source such as marketing communications. Awareness of such a need motivates the consumer to search for information about options with which to fulfill the need. This information can come from personal sources, commercial sources, public or government sources, or the consumer's own experience. Once alternatives have been identified through these sources, consumers evaluate the options, paying particular attention to those attributes the consumer considers most important. Evaluation culminates with a purchase decision, but the buying process does not end here. In fact, marketers point out that a purchase represents the beginning, not the end, of a consumer's relationship with a company. After a purchase has been made, a satisfied consumer is more likely to purchase another company product and to say positive things about the company or its product to other potential purchasers. The opposite is true for dissatisfied consumers. Because of this fact, many companies continue to communicate with their customers after a purchase in an effort to influence post-purchase satisfaction and behaviour.
For example, a plumber may be motivated to consider buying a new set of tools because his old set of tools is getting rusty. To gather information about what kind of new tool set to buy, this plumber may examine the tools of a colleague who just bought a new set, read advertisements in plumbing trade magazines, and visit different stores to examine the sets available. The plumber then processes all the information collected, focusing perhaps on durability as one of the most important attributes. In making a particular purchase, the plumber initiates a relationship with a particular tool company. This company may try to enhance post-purchase loyalty and satisfaction by sending the plumber promotions about new tools.
