The major stages in the consumer buyer decision process are actually a systematic method of the Marketing, in order all the consumers can be engaged into all the purchases, such as the buying of a house or car to the groceries of the day. To be precise, it is the process which mixes the psychology of consumer behaviour and the interests of marketers in understanding the behaviour of the consumer, in order to produce more effectively market products and services to them. The approach has multiple steps. However the major stages are five which are the following.
Need recognition is the first stage of the decision-making process. To be precise, this step is actually the process in which the consumer performs a basic research for the product or the providers which are interested him, if they can cover his needs and offer to the consumer the best solution for him. Moreover, this stage has two processes, an internal and an external process. Internal process is a recall of past experiences. External process is the use of other resources such as internet or discussion with other consumers. (Kotler and Armstrong 2008)
