make purchasing
decisions?
The consumer passes through 5
stages during buying process
Problem recognition
Information Search
Evaluation of Alternatives
Purchase decision
Postpurchase behaviour
Problem recognition
A problem or need is triggered by internal
or external stimuli
Internal stimuli- Hunger, thirst.
External stimuli – your friend’s new car!
Marketers need to identify the circumstances
that trigger a need

Evaluation of Alternatives
Our Belief and Attitudes determine
behaviour towards products
and services
Companies tend to fit their products
into the existing attitude of consumers
Evaluation of Alternatives
Expectancy Value Model of attitude formation
posits that
Consumers evaluate products by combining their brand
beliefs
Say you buy a laptop,
you give 50% importance to memory capacity,
30% to graphics,
20% to price.
Then you rate alternatives based on these factors
Purchase Decision
During purchase , consumers make 5 subdecisions-
Brand
Dealer
Quantity
Timing
Payment Method
Purchase Decision
NONCOMPENSTAORY MODELS OF CONSUMER
CHOICE
Involves choice heuristics(shortcuts)-
Conjunctive Heuristic (deciding a minimum cutoff of an
attribute)
Lexicographic Heuristic ( Based on most important attribute)
Elimination by aspects Heuristic
(probabilistic choice of an attribute based on importance)
Purchase Decision
INTERVENING FACTORS like
Attitude of others towards
product, and
Unanticipated situational factors , like losing job
influence decision
Perceived risks(like financial, physical, functional risks)
influence buyer behaviour
Marketers must provide proper knowledge for risk reduction
Postpurchase behaviour
Marketing communications should supply beliefs that reinforce
the consumer’s choice
Postpurchase satisfaction , actions , use and disposal
must be monitored
