Twelve weeks of handover is not enough when the writing is supposed to happen alongside the shift.
The handover is planned as an overlap period: the experienced line operator is supposed to document what he knows. In everyday work, a breakdown gets in the way, and what ends up recorded is what the maintenance schedule says anyway. The special knowledge, the fault pattern with its three exceptions, stays in his head and leaves with him.
38years of serviceThe line operator has known the line since it was commissioned.
12weeks of handoverThat is how long he overlaps with his successor.
6fault patterns with no entryThey appear in no maintenance schedule, because they occur so rarely.
9months of onboardingThat is how long the successor needs before he can solve the same cases on his own.
On the last working day, the six fault patterns sit as searchable entries in the knowledge base instead of in the colleague's head: up to 60% less knowledge loss.
The reduction of up to 60% in knowledge loss is this agent's headline figure. The six fault patterns without an entry and the nine months of onboarding sketch a typical handover; nobody counted them.
