Comparison at a glance
| Decision | AI-assisted step | Rule-based step |
|---|---|---|
| Input pattern | Variable language or information needing interpretation | Known fields, states, events, and explicit conditions |
| Output check | Compare meaning and required evidence, not only format | Check the condition, resulting action, and exception path |
| Typical risk | Plausible but unsupported or inconsistent interpretation | Incorrect rules, incomplete inputs, or duplicate execution |
| Fallback | Human review or a documented manual route | A visible failed-run queue and controlled recovery |
How the distinction appears in product documentation
Microsoft documents event- and time-triggered flows in Microsoft Power Automate cloud flows and describes adding a prompt action and human review in Microsoft: prompts in Power Automate. These are implementation patterns, not proof that a particular workflow is ready for autonomous operation.
When the first approach fits
Evaluate AI for a bounded drafting or classification task when someone qualified can inspect the result. Measure total review and correction effort, and include difficult examples in the pilot.
When the second approach fits
Use explicit rules for responsibilities such as assigning a known territory or routing a complete form to a defined owner. Rules still need monitoring and safe handling of missing or repeated events.
Worked decision example
Illustrative example: a rule routes an accepted agreement using a verified customer region. An AI step drafts a handoff summary from notes, but the receiving owner checks the draft against the agreement before it becomes a delivery commitment.
A practical selection test
Build a representative set containing ordinary, incomplete, ambiguous, and duplicate inputs. Check the business outcome and recovery route. Combining rules, AI, and approval can be more appropriate than choosing one approach for the whole workflow.
What the proposal must resolve
Ask for the exact work boundary, internal counterpart, access requirements, deliverables, and acceptance evidence. Clarify what happens when new information changes the brief. Compare the work your team must still perform, not only the outside fee or the name of the service.
