The document discusses the consumer decision making process. It begins with problem recognition, where the consumer identifies a need. The consumer then gathers information on alternatives to evaluate and make a purchase decision. This process is influenced by economic, psychological, and environmental factors. The document then describes the different types of consumer decisions - extensive/complex, dissonance reducing, habitual, variety seeking, and the levels of purchase involvement - low, medium, high. It also discusses the different types of consumer problems - active, inactive, routine, emergency, planning, evolving - and how marketers can discover, respond to, help recognize, or suppress problem recognition.
