Why divergent people data is the most expensive kind
In most plants information about a worker is split across several independent sources: the HR system knows the contract and department, a safety spreadsheet knows the training, a calendar knows the examinations, and the shift leader knows who actually does what. Each source is current within its own scope and out of date in every other.
The gap only shows at the edges. Someone moves from warehouse work to operating a forklift and formally stays in the old training group. Someone returns after a long absence and nobody connects that fact with a follow-up examination. Someone is moved to another shift and their qualifications remain attached to the previous supervisor.
The result is rarely a spectacular mistake — it is a quiet erosion of trust in the data. After a year nobody relies on the list, and before an inspection everything is checked by hand, person by person. That is why the Employees module is not an administrative extra in VIMS; it is the layer the other processes stand on.
