A Consumer-Based Approach to Designing Product Line Extensions

A high proportion of new product introductions entail line extensions (e.g., new flavors, sizes, convenience packs, features) rather than totally new products. An attendant problem with line extending involves the possibility of cannibalization of the firm's current products. Paul Green and Abba Krieger describe an approach for designing line extensions that employs consumer tradeoff data and a variety of search heuristics to find "optimal" extensions that explicitly consider the cannibalization of current offerings. The methodology is applied to a case in which an agricultural chemicals firm is introducing a new soybean herbicide.
