Traditional software behaves predictably.
AI doesn’t, and that changes everything.
In non-AI software:
Requirements = clarity + control.
Same input → same output.
In AI systems:
Requirements = guardrails + boundaries.
Same input → multiple valid outputs.
You define what the system can’t do, and what “good enough” means.
Most PMs miss this mindset shift because deterministic thinking breaks in probabilistic systems.
For example:
Wrong password → show error. (Predictable.)
“Recommend the best song right now” → no single right answer.
Only probabilities.
That’s why AI PMs ask different questions:
- What accuracy range is acceptable?
- What failures must never happen?
- How should the product behave when it’s uncertain?
- Where are fallbacks needed?
- What does “safe” actually mean here?
Requirements shift from fixed outputs → flexible constraints.
And this impacts everything:
- Roadmaps: milestones = model improvement
- UX: UIs must support uncertainty, editing, and explanations
- Testing: evals > test cases; quality becomes continuous
If you are building AI products, this mindset isn’t optional anymore.
I’m breaking this down further in the upcoming AI PM masterclass.
