Abstract
This research examines how project duration relates to specific individual risk factors that threaten virtual projects, i.e. where team members are not co-located and must rely heavily on computer mediated communication. A total of 557 project management practitioners completed an online survey concerning the impact of each of 55 risk factors on one of their recently completed virtual projects. MANOVA analysis on the ten factors with the highest risk effect (REff) levels demonstrated a clear relationship between project duration and six of the ten factors. These six risks were significantly higher on longer duration projects, suggesting that (1) these risks need to be followed more closely on longer duration projects, and (2) projects whose schedules increase over time may be at greater risk than their risk analyses might indicate. Reasons why some risk factors have a duration effect, while others do not, are explored.
