Manufacturing Cost Intelligence System becomes a real thinking tool

Took the idea of ‘flight simulator for manufacturing decisions’ and pushed it far enough that you can actually feel portfolio-level impact in a slider move.

Quick scan

Context I wanted a decision tool that replaces fragile spreadsheets with fast, portfolio-level visibility.

Breakage Too much logic in the UI; early AI was just narrating charts; static CSVs tempted me to pretend it was production-ready.

Takeaway Separate brain from UI, feed feasibility explicitly, and be honest about what is V1 vs production.

What changed the quality level

Built a first version tying BOM, cost drivers, and demand into a portfolio simulator.

Refactored to keep core logic separate from Streamlit UI.

Making the AI not cringe

Had to feed feasibility and tell it what not to say so it behaved like a junior consultant, not a narrator.

The honest limitation

Static CSVs are great for controlled experiments. Not production-ready without live integrations.
