Purpose - The purpose of this paper is to elucidate the factors influencing creativity in information system development ISD). Specifically, this paper compares two groups, students and practitioners, in order to identify salient factors influencing creativity in this field. Design/methodology/approach - An empirical study was conducted through two online surveys in Taiwan. The subjects were university students n = 220) and practitioners n = 187) who had ISD project experiences. Data were collected via an online survey and analyzed using partial least squares PLS) structural equation modeling. The authors present state-of-the-art PLS path modeling, including heterotrait-monotrait, standardized root mean square residual, second-order identification, and partial least squares multigroup analysis PLS-MGA). Findings - Both the student and practitioner results showed that the most salient factor influencing creative behavior was use of creativity technologies. In addition, cognitive style, recognition, and database programming had a significant positive effect on creative behavior for the students but not for the practitioners. The PLS-MGA results indicated that differences in creative behavior between the students and practitioners need to be considered. Research limitations/implications - There are two main limitations. The first one is its design. This study was cross-sectional and there is a likelihood of common source bias due to self-reported data. In the future, researchers can use brain-imaging tools e.g. functional magnetic resonance imaging fMRI)) or eye tracking measurement to reduce self-reporting bias in creative behavior research. The second limitation is related to the sample. The subjects were university students and practitioners who had ISD project experiences; however, the heterogeneity of the investigated individuals e.g. background, ability or experience) in university or industry may limit the power and generalizability of this study. Future studies may take same samples into consideration. Originality/value - No previous study has investigated factors influencing the creativity of information system IS) students and practitioners by using a decomposed and second-order research model. Thus, this paper, based on Amabile's creativity theory, attempts to elucidate the factors influencing IS students' and practitioners' creativity.
