A spreadsheet used as a primary system of record for business-critical data, bypassing official IT management and reliability controls.
Problem analysis
A. Symptom

Visible Signal

"Version 14_Final_Actually_Final.xlsx" is the main ledger.

B. Business Impact

Consequence

Inability to automate or scale the business operations.

C. Hidden Failure

Architecture Flaw

Using a calculator as a warehouse.

Root cause

Excel is a calculation tool, not a storage tool. It lacks the fundamental requirements of a database: immutability, relational integrity, and multi-user concurrency.
