It is one of the several models of consumer behaviour, which subscribes to a distinctly
cognitive and information-processing point of view. In this model, the consumer is portrayed as possessing a limited capacity for processing information. When faced with a choice, the consumer rarely undertakes very complex analyses of available alternatives. Instead, the consumer typically employs simple decision strategies or heuristics. These simplifying decision rules assist the consumer in arriving at a choice by providing a means for sidestepping the overly overburden task of assessing all the information available about all the alternatives.
