The paper considers two issues of business process flexibility; first, the fit between organizational structure and organizational processes and, second, dynamic job assignment based on dynamic knowledge maps. Organizational structure usually is considered to be more stable than organizational processes. However changes in the processes can cause appearance of emergent organizational structures, which are more effective than formal ones. Business process model analysis is needed to identify when the formal structure is to be replaced by an emergent one. Dynamic knowledge map is changed each time a person performs some new task in the process. This allows to track experience of employees and thus to base job assignments on up-to-date information about their knowledge.
