Design Fixation in the Wild: Design Environments and Their Influence on Fixation

Many studies of design fixation ask designers to work in controlled laboratory or classroom environments, but innovative design work frequently occurs in dynamic, social environments. The two studies reviewed in this paper investigated how three independent variables likely to be present in many design environments affect design fixation. The first study found that working with physical prototypes significantly reduced fixation effects, and that working in groups can reduce fixation effects under certain conditions. The second study found that brief interruptions in designers' thought processes during the initial states of the design process also reduce fixation effects. I conclude by discussing what the data from both studies may indicate about the theoretical causes of fixation effects, and what designers might do to prevent fixation from affecting their creative output.
