A homegrown scheduling tool, a warehouse system customized for fifteen years, a spreadsheet macro the month-end close depends on. The software keeps running. The judgment around it lives with one or two people: which screens to trust, which errors are normal, and which workaround is holding something up.
Someone added a manual step years ago to cover a gap in the system. It looks like waste. A new manager removes it, and the problem it was covering comes back months later.
Data moves between systems on rules that were never written down: field mappings, timing, and what happens when a record fails. When that person leaves, every interface error becomes an investigation.
Replacing the system means listing every rule it enforces. Without the people who know them, the discovery phase grows, the quote grows with it, and the project gets deferred again.
We build the vault: your company's knowledge, kept safe and open to your teams and systems. For legacy and custom software, that means the reasoning the code and the manuals leave out.
Why the system is configured the way it is, and what was tried and rejected.
Which errors and warnings are normal, and which mean stop.
Every manual workaround, what it protects, and when it is safe to remove.
How data really moves between systems, including what happens when it fails.
The rules a replacement system will have to reproduce.
Delivered into your data platform, as a tool your people search, or as SOPs and training for successors. See where it goes.
Tell us who is leaving, what they run, and roughly when. That is enough to have a useful first conversation about scope.
