Shift handovers that don't drop tasks: a checklist for kitchens and building sites

The lunch cook knew the walk-in was running warm and had called the repair company. The dinner cook didn't. The day foreman knew the east trench wall had slumped after the rain. The night crew didn't. In both cases nobody forgot anything; the information just never made it across the shift change.

Handovers are where shift work leaks. The fix isn't a longer meeting. It's a short, fixed structure, a written record of open items, and one habit that most crews skip: the incoming person says it back.

What hospitals learned

Hospitals hand patients between shifts several times a day, and they have measured what goes wrong. The best-known study is I-PASS, published in the New England Journal of Medicine in 2014 by Amy Starmer and colleagues. Nine children's hospital residency programmes in the US and Canada brought in a structured handover: a fixed order for what is said, a written handover document, training, and the receiver summarising back.

Across 10,740 admissions, medical errors fell from 24.5 to 18.8 per 100 admissions (23% fewer) and preventable adverse events, the errors that actually harmed someone, fell from 4.7 to 3.3 (30% fewer). Time-and-motion checks found the new handovers took no longer than the old ones.

A kitchen or a building site is not a hospital ward, and nobody has run that trial in a restaurant. But the failure is the same kind: one person holds the context, the next person needs it, and a casual chat at the door loses pieces. The structure transfers well.

The five parts, adapted for a crew

I-PASS stands for Illness severity, Patient summary, Action list, Situation awareness and contingency planning, Synthesis by the receiver. Translated for kitchens and sites:

1. Status in one word. Calm, busy, or problem. The incoming lead knows at once how much attention to give the rest.
2. Summary. What happened this shift in two or three sentences: covers served and what's left in prep, or which pour got done and which didn't.
3. Open tasks, each with an owner and a time. Not "the dishwasher's playing up" but "dishwasher rinse arm blocked, repair booked 6 pm, Ravi to let them in".
4. Watch-outs and if-thens. What could go wrong next shift and what to do if it does: "If the walk-in reads over 41°F again, move the dairy to the reach-in and call the number on the door."
5. Read-back. The incoming person says the open tasks and watch-outs back in their own words. This is the step that catches what was mumbled or misheard.

A handover isn't finished when the outgoing person stops talking. It's finished when the incoming person can say it back.

Kitchen handover checklist

Temperatures, with numbers. The US FDA Food Code (adopted, sometimes with changes, by most states) sets cold holding at 41°F (5°C) or below and hot holding at 135°F (57°C) or above. Write the actual readings for each walk-in, reach-in and hot well, not "fridges OK". Check your own local code; it may differ.
Anything cooling. Food cooling down has two time limits (135°F to 70°F within 2 hours, then to 41°F within the next 4 under the Food Code). Hand over what's cooling, when it started and when it's due to be checked.
86'd items and low stock, so front of house hears it before a guest does.
Equipment faults and who has been called.
Allergen or special orders still in progress.
Prep left for the next shift, with quantities.

Construction handover checklist

Inspections due. US OSHA rules, for example, require a competent person to inspect scaffolds before each work shift (29 CFR 1926.451(f)(3)) and excavations before work starts and as needed through the shift, and again after rain or anything else that raises the hazard (1926.651(k)). Hand over what was inspected, by whom, and what changed since.
Changed conditions: weather, a slumped wall, a moved barrier, a delivery left in the access route.
Work left half done, and what state it's in ("formwork up on grid C, not yet checked").
Permits and isolations still open: hot work, lockouts, confined spaces.
Deliveries and visitors expected next shift.
Photos of anything you describe. A picture of the slumped wall saves a paragraph and an argument.

Write it where the next shift will look

I-PASS combined the spoken handover with a written one. For a crew, the written part works best as open tasks on a shared list rather than a notebook by the till: each item has an owner, a due time and a photo where it helps, and the next shift ticks items off instead of rewriting them. Items nobody picks up stay visible, and the weekly review is where recurring ones get fixed for good.

Keep the spoken part short: five minutes for a kitchen, ten for a site. If it runs longer, the written list isn't doing its job.

What this does not show

The I-PASS figures come from children's hospitals, with training and a culture-change campaign alongside the checklist; a restaurant won't see the same numbers. The 23% and 30% are relative drops. The regulations quoted are US rules and examples only; your local food and safety codes decide what you must record.

To write tonight's handover in this order, use the shift handover note: it runs in your browser, puts the status, open items, readings and watch-outs on one page, and prints or copies as text.
