This study represents research-in-progress that investigates the factors motivating employee choice of information and communication channels for sharing knowledge. A pilot study was conducted to determine what channels are available, what channels employees actually use, and why they employ those channels. Participants responded to an online questionnaire. Preliminary results show that employees have a wide variety of channels available. Face-to-face, telephone, and e-mail are commonly used for knowledge sharing while Web 2.0 technologies remain underutilized. Channel choice appears to be influenced by the type of knowledge to be shared, among other things. Based on the results and extant literature on practice-based research and cross-boundary knowledge sharing, a model is developed to guide our future research.
