Luc’s question: what is the causal relationship between Run a workflow and Produce Mosaic?
What solution?
•
Not too sure
•
The controller of a process could be an artifact
•
Several artifacts could denote different
instances of a same entity, which is the agent
•
Agency is the common property of these
artifacts
•
Should the agent be seen as a form of stream
of artifacts?
Delve into the concept of agents in OPM Workshop facilitated by Luc Moreau. Explore the nature of agents, their differences from artifacts, causes of their behavior, and challenges in their utilization. Discover the role of enactors, executables, and workflows in generating and controlling agents. Unravel the causal relationship between workflows and artifact production, questioning the essence of agents as a stream of artifacts.
