"How to answer a software question you don't know"

💬
Honest, methodology-first response

"I haven't used [tool] directly, but I've used [comparable tool] which works on the same [GHG Protocol / ASHRAE / LCA ISO 14040] basis — so the migration is methodology-first, UI-second. I've found tool transitions take me about 2–4 weeks for a major platform. Could you tell me how it's deployed in your team so I can be specific about the gap?"

This works because: (1) honest, (2) methodology-first, (3) shows tool transitions are routine, (4) asks an intelligent question back.
