Professor Henderson, addressing the suggestion that the focus in product design liability cases should be on the process by which design decisions are made rather than on the reasonableness of a particular design, analyzes a proposal that manufacturers be able to present evidence of good process as a defense. Although he applauds the attempt to resolve the difficulties of deciding product design cases, he questions the soundness of the process approach. Specifically, he argues that a process defense would be unworkable because judges would be unable to tell good process from bad, and that the proposal does not address polycentricity--the real source of difficulty in product design cases. Finally, he is unconvinced that a process defense will provide incentives that would lead to improved product designs
