A fragile house of cards filled with hidden errors, broken formulas, and misplaced decimal points.
A digital spreadsheet used for organizing, calculating, and analyzing data. The one tool that somehow runs the entire company, despite having 5,000 hidden errors. No matter how many fancy BI tools are implemented, someone will always ask for "just a quick Excel export." Will be emailed back and forth until five different versions exist.
"This billion-dollar company runs on an Excel sheet with 42 tabs."
