I fumbled this a bit at first because I started listing use cases instead of talking about the decision criteria.
Frame your answer around a decision framework that starts with the problem's core requirements—data availability, need for personalization or creativity, tolerance for errors, and scalability—then map those to the simplest technology that can deliver. Emphasize that you always default to the least complex solution that meets user needs, and only escalate to AI or agents when traditional approaches fall short. Use a concrete example from your experience to illustrate the trade-offs.
Pro tip: Show that you understand the cost and maintenance implications of each approach—AI and agents require ongoing data pipelines, monitoring, and iteration, while rules-based systems are cheaper but brittle. Mentioning total cost of ownership and time-to-market will set you apart.
Clearly articulate the user problem, desired outcome, and how you'll measure success (e.g., accuracy, latency, cost, user satisfaction). This sets the bar for what technology is needed.
Determine if the problem requires pattern recognition, natural language understanding, or generation (favoring AI/GenAI), or if it can be solved with deterministic logic and structured data (favoring traditional software or rules).
Consider how costly mistakes are and whether the system must adapt to new inputs over time. High error tolerance and need for adaptability point to AI; low tolerance and stable rules point to rules-based or traditional software.
If the problem involves multiple steps, tool use, or dynamic decision-making with minimal human intervention, an agent-based system may be appropriate—but only if the complexity is justified by the value.
Begin with the simplest viable approach (e.g., rules or traditional software) and only add AI or agents if it fails to meet metrics. Use A/B testing and user feedback to guide escalation.
