A shop that runs three shifts faces a problem a single-shift shop never has: the handover. Tools go missing, half-finished jobs are misread, and a fault noticed at the end of one shift is forgotten before the next crew arrives. The usual fix is a written log, but logs are only as good as the discipline behind them. Shops that manage handovers well tend to do one thing in common, which is to overlap the shifts by fifteen minutes so the outgoing and incoming crews speak face to face.
