The most expensive system in the company was free.

It started as a spreadsheet.

Someone created it to solve a small problem.

A few months later:
More columns were added.
More people started using it.
Important decisions depended on it.

Soon it became the source of truth.

The problem?

Nobody owned it.
Nobody maintained it.
Nobody knew what would happen if it disappeared.

What started as a quick fix quietly became critical infrastructure.

This is something we see often at BrainPack. Many organizations think their core systems run the business. In reality, some of the most important workflows are hiding inside tools that were never meant to be permanent.
