Why Your Data Lineage Is Still a Spreadsheet (and How to Fix It in 5 Minutes)

The Heisenberg Problem: Why Observing Your Data Pipeline Breaks Your Documentation

Or: How to stop lying to your auditors (and yourself)

There's a principle in quantum mechanics that says the act of observing a particle changes its behavior. Your data lineage documentation has the opposite problem: the moment you stop observing it, it collapses into a superposition of "probably still accurate" and "completely wrong."

You know the drill. Six months ago, someone built a meticulous lineage diagram in Lucidchart. Three sprints later, the ETL got refactored. Two months after that, a new Snowflake schema appeared. Last Tuesday, someone quietly renamed a column. Today, your compliance audit starts at 9 AM.

The spreadsheet is open. The cursor is blinking. The coffee is cold.
