System Boundaries: The Difference Between ChatBot, Workflow, Agent, and Harness
The article discusses the distinctions between ChatBot, Workflow, Agent, and Harness systems in engineering. It emphasizes that each system serves different purposes based on the level of uncertainty and complexity involved in tasks. Understanding when to use each system is crucial for effective project management and execution.
- ▪ChatBot is suitable for conversation problems, while Workflow addresses deterministic process issues.
- ▪Agent systems are necessary for dynamic decision-making when task paths are uncertain.
- ▪Harness is required for stable hosting and control when an Agent operates in a real environment.
