28. RATIONAL MODEL: Assumes comprehensive rationality - comprehensive search for alternatives, their systematic evaluation against objectives, choosing the alternative that maximises value. Satisficing Models: Based on the concept of bounded rationality - people do not have the cognitive capacity to be comprehensively rational; hence they ‘satisfice’.
