In the literature it has been suggested that willingness to cannibalize might explain why certain organizations are better at developing radical innovations than other organizations. Yet, a closer inspection of the literature suggests that organizations may cannibalize on previous investments, capabilities, and sales, lending support for the notion of a three-dimensional construct of willingness to cannibalize. The construct was then tested using a sample of Dutch companies. The results confirmed the three-dimensions of willingness to cannibalize. The construct and its dimensions showed anticipated different relationships with other NPD constructs, e.g. future market focus and risk posture of top management. In a second, larger study involving a panel of Dutch SMEs the construct was further checked and its effect on the type of new products developed investigated. Two out of three-dimensions of willingness to cannibalize were correlated with turning out more radical new products. There also was a positive correlation with financial performance. The results confirm that willingness to cannibalize is a multidimensional construct and plays an important role in predicting new product radicalness. (c) 2005 Elsevier Ltd. All rights reserved.
