The flow experience can be an important precursor to high levels of creativity and innovation. Prior work has identified and conceptualized the key elements of the flow experience in cocreative activities as individual flow corridor, individual flow feeling, and group flow. Surprisingly, the flow experience is underrepresented in theory and practice of design thinking. In this empirical study, the flow experience at the individual and group level was investigated in a 1-day design thinking exercise. The findings from partial least squares (PLS) modeling of 230 observations confirm previously untested conjectures that (a) the elements of individual and group flow experience were prevalent and highly correlated in the design thinking activities and (b) the nature of the design thinking task had an impact on the flow experience. Finally, results confirm that Lego Serious Play skills-building as a creative warm-up had a positive effect on 2 of the 3 flow experience elements: individual flow feeling and individual flow corridor.
