Discussion and conclusion
The objectives of the present study are: to examine the relationship of uncommon use of knowledge to IS departments’ routine performance and innovative performance, which together represent such departments’ overall performance; and to explore the factors that foster uncommon use of knowledge from an HRM perspective. Our empirical results indicate, first, that knowledge adaptation had a significant effect on both aspects of departmental performance, while knowledge augmentation was more critical to innovative performance than to routine performance. Our second key finding was that high uncertainty avoidance and high communication enhanced knowledge adaptation, while teamwork design and innovation-based policies were critical to promoting knowledge augmentation. We also found that shared decision-making was essential to both knowledge augmentation and knowledge adaptation, but much more critical to the former.
The positive impact of uncertainty avoidance on knowledge adaptation is in line with the prior findings by Erez and Nouri (2010), who argued that individuals in uncertaintyavoidance cultures focus on elaborating the usefulness and appropriateness of their ideas to the situation in order to reduce ambiguity, primarily when working on a well-defined task. Likewise, our finding that within-team communication significantly impacted knowledge adaptation is consistent with research by Akgün et al. (2014), who demonstrated the critical effects of communication on information acquisition, dissemination, and implementation, which in turn improved project outcomes. The impact of teamwork design on knowledge augmentation has been consistently identified in past studies (Hoegl and Parboteeah, 2007; Okhuysen and Eisenhardt, 2002; Tiwana and Mclean, 2005).
