In times of continuous changes organizations face the need to react quickly to experienced or occurring changes and to act pro-actively to foreseen developments. An effective way for organizations to (re)act is to model the business at the process level and to reconstruct or rearrange this representation according to the needs for dynamic adaptation. Required changes can be explored dynamically and possible solutions evaluated before implementation - organizational development can occur iconlineln. Once business processes with the user interfaces can be executed, organizational changes and solutions become transparent to employees.

The framework for organizational learning emphasizes individual and shared mental models. According to the framework, the execution of business processes effects single- and double-loop organizational learning.
