The quietest failure in a technology project is a system that went live, works, and nobody logs into. No errors, no complaints, and in the reports everything looks fine.
The first sign appears in week one: people keep asking questions on WhatsApp instead of opening the system. That's not laziness — it means the system is slower than the old way for that task.
The second sign is partial use. The team enters what's mandatory and skips the rest, so the data is incomplete and the reports can't be trusted. At this point managers start asking for the old spreadsheet "just to cross-check".
What works is measuring actual usage from the very first week: how many people logged in, how many records were opened, which screens nobody touches. That shows exactly where the process doesn't match reality.
Then you fix the process, not the training. If a screen asks for seven fields and three are needed — remove four. Adoption isn't persuasion, it's adaptation.
The bottom line
A project's measure of success isn't go-live but actual usage a month later. We measure it, and fix things based on it.
