Buying process involves purchase need, decision makers, information search, alternatives evaluation, purchase decision and post purchase behaviour. Companies try hard to understand consumer experience and expectation at every stage of buying process. Marketers need to figure the right combinations which will initiate purchase need e.g. marketing programs. Companies should ensure consumer have readily available information to take the decision e.g. internet, friends. Consumers evaluate alternatives based on their brand perception and belief. Companies need to work hard to develop products, which match this perception and belief every time. Final purchase decision is taken looking other’s perception of the brand. Post purchase if expectations meet actual performance consumer is satisfied and more likely to repurchase or recommend the brand to others.
