Rebuilding a control tower without turning the trucks off.

The operations floor ran on one enormous spreadsheet. It had accreted around the business for six years. It was, in a meaningful sense, the business. The task was to lift it out of that seat, calmly.

The first rule

We did not replace the spreadsheet. Not at first. We instrumented it — silently — so that for three months every action taken on it was also a row in a structured event log. Only when we understood how the business actually behaved did we start moving work into a proper system.

"They treated our sheet as a patient, not a problem. Nobody had done that before."

Sequence

Visibility first. Then the parts of the workflow where exceptions were already well understood. Then the hard, ambiguous edges. The spreadsheet stayed live, read-only for the last six weeks, as a comfort object. It was retired without ceremony.

What changed

The client now runs three regional operations on the same control tower. A fourth is planned for 2026.
