EngelKollatBlackwellin
EngelKollatBlackwellin refers to the Engel–Kollat–Blackwell model of consumer behavior, commonly called the EKB model. Developed by James F. Engel, David T. Kollat, and Roger D. Blackwell in the 1960s, it was first described in their influential 1968 book on consumer behavior. The model outlines how consumers move through a structured process when making purchases and highlights the interplay between internal psychological factors and external influences such as culture, social groups, and marketing communications.
The core framework identifies a sequence of stages: problem recognition, information search, evaluation of alternatives, purchase
Key features of the EKB model include its recognition of information processing as a dynamic, non-linear process
