(Kotler and Keller, 2012).
The consumer Behaviorism model suggested that consumer’s purchase behavior generally
passes through 5 stages, before and after the actual purchase, include needs recognition,
information search, evaluation of alternatives, purchase decision and post-purchase behavior.
According to the model, all the external influence and internal influence on consumer result in their social concept and lifestyle choice. Lifestyle of a consumer refers to a pattern of consumption reflecting their choices as how they spend their time and money; it also refers to the attitudes and values attached to these behavioural patterns (Solomon, 2006). According to Kotler et al, “Lifestyle is a person’s pattern of living as expressed in his or her activities, interests and opinions”. Lifestyle captures a person’s whole pattern of acting or networking in the world more than profiling a person’s social class or personality. (Kotler et al, 2009). Life style and social concept of consumer influenced by their external and internal influence result in the decision making process for the product based on need and desire.
