Non-compensatory Decision Rules Accept alternative only if each criterion equals or exceeds the minimum cutoff level. A product is acceptable only if it exceeds the minimum level on at least one criterion Crank criterion from most to least important and choose best alternative on most important criterion Select one criterion and eliminate alternatives that don’t exceed it’s established cutoff level. Continue eliminating until one alternative remains. Conjunctive Disjunctive Lexicographic Elimination by aspects
