This study examined the individual and combined effects of the organisational-level variables of climate and task design, and the group-level variables of group citizenship behaviour (GCB), market orientation, group self-efficacy (GSE), and group climate for innovation (GCI) on work group service innovativeness. Specifically, this study theorised that work group service innovativeness is a product of both organisational (organisational climate and task design) and work group (GCB, market orientation, and GSE) contexts. Drawing upon the theories and literature, six hypotheses were derived. Data were collected through a 64-item questionnaire using a 7-point Likert scale from four hotels in Melbourne, Australia. Results indicated that organisational climate, task design, GCB, group self-efficacy, and group climate for innovation were significant predictors of work group service innovativeness, while market orientation was not. Limitations, future directions, managerial and research implications are explored.
