Chapter 2 constructive consumer choice process Chapter 2.1 How constructive consumer choice process measures which attribute factor(s) can influence consumer chooses to buy any product or food in psychological view. Main Problem Being Addressed The second aspect problem is judged whether constructive consumer choice is an important process to influence any consumer to choose to buy any products. If it is a real essential choice process, how product manufacturers can reduce their negative emotion is caused to choose not buy their products during this constructive process. The second aspect main problem is researched about consumer will choose to make final decision to buy the best choice of product from among brands of products . Hence, the constructive consumer choice process is a real essential choice process to any consumer generally, when individual consumer needs to compare different brands of products to choose to buy any product. How product manufacturers can predict whose choice method to decide to prefer to make final decision to buy any products in the short days or the short time in the constructive consumer process. If manufacturers can know overall consumers' choice method, manufacturers will not design the not suitable style of products to manufacture to sell and who can know what the overall consumers' negative emotion is influenced who decide not to buy their products from their design style in order to manufacture more suitable style of product design . I shall recommend how manufacturers can predict consumer emotion in the constructive consumer choice process in psychological view.My research is concerned knowledge opinion about how to predict consumer emotion whether what attribute factor(s )are the most influence to the consumer to choose to buy the manufacturer's product in whose process of choice. If manufacturer can early know whether what the most attractive attribute factor(s) are the most influence to the consumer to decide to buy whose product, so who can concentrate on manufacturing the different kinds of products to get the most influence attribute factor to attract consumers to choose to buy whose products. Hence, the manufacturer can know what reasons can cause the consumers who do not choose to buy its products during constructive consumer choice process generally, who can know how to improve its product's design method to concentrate on producing the most acceptable satisfactory level to sell to whose consumers in .Also I believe that the manufacturer can raise sale numbers if who know what bad factors to cause whose consumers choose not to buy whose products during the constructive consumer choice process. It can increase chance to change its product innovative strategy to raise confidence to judge what attributed factors are the important influence to cause consumers who either do not choose to buy or choose to buy its innovative products.
