What a Handover Has to Carry

The difference between a report and a handover — and the four things every shift change has to move.

Most handovers tell you what the last crew did. They don't tell you what the next crew has to watch.

That's the difference between a report and a handover.

A report looks backward — jobs done, readings taken, samples sent. Good for the record. Useless at 7pm, when you're about to take responsibility for a live plant.

01A handover has one job

A handover has one job: move the plant safely into the next twelve hours. And a plant doesn't care what you did last shift. It cares what's about to happen.

So a handover that actually works carries four things the logbook usually doesn't:

  • The watch-items. The pump running hot but not tripped. The valve that's passing. The thing that's fine right now and won't be by 3am.
  • The half-finished work. Not "started the changeover" — but exactly where it stopped, what's isolated, what's still live, and what has to happen before it's safe to run.
  • The changes. What's different from how the incoming crew left it last time — new line-ups, a bypassed trip, a permit still open.
  • The judgement. The part that never survives on paper: "keep an eye on number three, it's been behaving strangely all night."

02The two kinds of missing

Miss the backward-looking stuff and you lose a record. Miss the forward-looking stuff and you lose the plant.

03Ask this of your next one

Next handover you run, ask one thing of it: if the incoming supervisor had only this, would they know what to watch tonight — or just what happened last night?

One shift boundary and what crosses it: a report that points backward at the shift just finished, the four forward-looking things a real handover carries, the difference between losing a record and losing the plant, and all four arriving with the incoming crew OUTGOING INCOMING THE SHIFT BOUNDARY REPORT jobs done, readings taken good for the record WATCH-ITEMS HALF-FINISHED CHANGES JUDGEMENT what the next crew watches A RECORD THE PLANT miss the backward stuff miss the forward stuff they are not the same loss WATCH-ITEMS HALF-FINISHED CHANGES JUDGEMENT all four, judgement included

A report looks backward — jobs done, readings taken. Good for the record, and useless at 7pm. The four a working handover carries. The last one never survives on paper. Miss the backward-looking stuff and you lose a record. Miss the forward-looking stuff and you lose the plant. If the incoming supervisor had only this, would they know what to watch tonight?
