In forestry work, conditions exist and develop that are complex, unpredictable, and highly consequential and therefore cannot be handled entirely by following static work procedures. Cognitive adjustments are necessary. The objective of this research was to determine whether performance (cognitive) variability is actually necessary to safely fell trees in the coastal region of British Columbia, Canada. In this paper two perspectives were contrasted: the traditional view of safety and the resilience perspective. A collection of empirical evidence established that while safe work procedures provide a good foundation, it is individual performance variability shaped by experience and ‘‘know-how’’ that guides the application of technical skills in such a complex, dynamic, high-risk environment.
