A Shift Passdown Example: 24 Hours, Three Shifts, One Machine Shop

Imagine a machine shop. You've probably worked in one just like it: about 80 people, three shifts, a row of CNC machines, a fab corner with a press brake and a saw, and a coffee maker that has outlived three plant managers. Follow it for 24 hours and you get a shift passdown example that shows every job a passdown (some plants call it a shift handover) has to do, and what each shift change looks like when the passdown lives in ShiftPanda.

Darlene runs days. Boyd runs seconds. Wendell runs nights. Patrice is the plant manager, and Gus is the maintenance tech who knows every machine by the noise it makes.

Darlene clocks in. Her coffee is still too hot to drink, which is fine, because Wendell's passdown is already sent and she reads it on her phone standing next to the time clock.

It's laid out the same way every morning: area by area, machine by machine.

The photo does a lot of work. "Leaking at the base" could mean a drip or a lake. The photo says drip, with a square of cardboard under it that someone has labeled DO NOT MOVE.

Darlene acknowledges the passdown, and her name shows on it. Wendell gets to go home without the five-minute parking-lot debrief.

The use case: a passdown written by area and machine, with status, notes and photos, so the incoming supervisor's first ten minutes go to reading, not detective work.

Patrice has the production meeting at 8:00. She doesn't text anyone to ask how the night went. She's an Admin, so she opens the night's passdown from her desk, sees HMC 3 sitting on the Open Issues list, and sees that Darlene has read and acknowledged it.

So the meeting starts at "HMC 3 is waiting on Gus" instead of "so, what happened last night?" It goes to deciding, not rebuilding the night, and nobody has to schedule a meeting about the meeting. There's more on this in how plant managers use the overnight passdown.

The use case: the plant manager reads what happened on every shift without walking the floor to collect it.

Cody, a crew member in Fab, walks over holding a part. The saw is wandering on its cuts. Not by much. Just enough to make the next operation miserable.

On a lot of floors, this is where the note goes on the back of a hand, a sticky note on a monitor or the memory of someone who will be very busy for the next three hours. Darlene logs it as an issue instead, against Fab and the saw, with a photo of the crooked cut. It goes straight onto the Open Issues list.

Logging it takes less time than the argument about whether it's the blade or the vise.

The use case: issues logged mid-shift by area and machine, so they don't depend on someone remembering them at 2 PM.

Darlene writes her passdown. A simple one takes about a minute. Today's isn't simple, so it takes under two.

She doesn't retype the saw. It's already there, carried over from the Open Issues list, along with HMC 3. She adds that the blade was swapped and the cuts are still off.

Halfway through, the Wi-Fi drops. It always does in the back corner by the press brake, where a steel rack eats the signal. When it comes back, everything she typed is still there. Nothing to install. It runs in the browser on her phone, and on the shop tablet Boyd uses.

Boyd has run seconds for three months. He's good, and he's still learning which machines lie. The passdown tells him which ones to watch, in the same order as every other day. (If you want to tighten what goes into yours, here's a shift passdown checklist.)

The use case: open issues carry over onto the next passdown on their own, and a dropped signal doesn't cost anyone their notes.

Gus stops by on his way out. "Did anybody tell seconds that HMC 3 stays down until the seal kit shows up?"

Boyd is pretty sure nobody did. The passdown says otherwise: the note is right there, and it shows that Boyd has read it. "Huh," says Boyd. "I did get that."

Nobody's in trouble. The question just gets settled before anyone's coffee gets cold, and nobody has to start a sentence with "I could have sworn."

An hour later, the office asks about the bracket order. Did Lathe 2 have a problem on nights last Tuesday? Boyd searches History by shift, area and date: night shift, Machining, last Tuesday. One card per area. There it is: a tool change and a note about a bad insert, written by Wendell at 3 AM a week ago, and nobody had to remember it.

The use case: read receipts end "I never got that," and History answers "what happened that night?" without a group chat archaeology dig.

Nights is a skeleton crew. Wendell is the only supervisor in the building, and at 2 AM the passdown is the closest thing he has to someone to ask.

Boyd's passdown gives him the night in order:

Compare that with a whiteboard that says "Saw weird." (The paper and whiteboard passdown has its charms. Detail isn't one of them.)

The use case: the night shift gets the whole story of the day, even when there's nobody awake to ask.

The quiet hour. Wendell takes a look at the saw and finds a loose jaw on the vise. Ten minutes and one test cut later, it cuts square.

He marks the issue done. It comes off the Open Issues list, and it won't show up on the next passdown. Nobody on days will spend the morning diagnosing a saw that's already fixed.

Gus still runs his work orders in the maintenance system. ShiftPanda doesn't replace that, or the MES. It sits alongside them and holds what those systems usually don't: what the floor saw, what's still open and what the next crew needs to know.

At the end of the month, Patrice will pull the Machine Issue Reports as an Excel file for her review with Gus, so the saw, HMC 3 and everything else that broke that month are on one sheet. (Admins can export them to CSV, Excel or PDF.)

The use case: an issue stays open until somebody actually fixes it, then it gets out of the way.

Darlene clocks in. Coffee: still too hot. Wendell's passdown: already sent.

The saw is done. HMC 3 carried over, because it isn't. Her first ten minutes are hers.

None of the moments above were dramatic. That's the point. A shift passdown does small, boring, important jobs all day and all night:

• Shows each area and machine the same way every shift, with status, notes and photos.
• Catches issues mid-shift by area and machine, so they don't live in someone's head.
• Carries open issues onto the next passdown until someone marks them done.
• Shows who has read and acknowledged it, by name.
• Keeps History you can search by shift, area and date.
• Runs in the browser on a phone or tablet, and keeps what you typed when the Wi-Fi drops.

Not with a rollout plan. With one supervisor and one crew.

1. Set up your areas and machines once. You know the floor better than anyone.
2. Run the passdown in ShiftPanda for a couple of weeks, alongside what you already do if that helps.
3. Bring the results to your plant manager. Open History and Open Issues together, and decide whether it's worth keeping.

If it isn't simpler than what you had, you'll know within a week. If it is, the coffee maker will be the only thing on the floor still running on tribal knowledge.
