Machine breakdown board: what goes on it, and a free printable
Every shop has one, even if it is a clipboard with a pen on a string. Here is what a breakdown board is for, the eight columns that make it worth the wall space, and the three mistakes that turn it into wallpaper.
A breakdown board is the place a shop writes down what stopped, when, and for how long. Whiteboard by the time clock, clipboard on the mill, sheet in a binder, tab in a spreadsheet. The form does not matter. What matters is that it exists, that the team actually fills it in, and that somebody looks at it once a week and does something.
Most boards fail on the third part. They get filled in for a month, nobody reads them, the team notices nobody reads them, and the board becomes a place to write phone numbers. This page is about building one that survives.
What a breakdown board is actually for
Not record keeping. A breakdown board exists to answer two questions the owner asks every month and nobody can answer from memory:
- Which machine is bleeding us? Not the one that broke most recently, the one that has cost the most this quarter. Memory always picks the recent one.
- What kind of problem keeps happening? Waiting on parts is a purchasing problem. No one free to run it is a scheduling problem. Mechanical failure on the same press four times is a Preventive maintenance problem. They look the same on the floor and they have completely different fixes.
If the board can answer those two, it pays for itself the first month. If it cannot, it is a diary.
The eight columns
This is the layout on the free printable at the bottom of the page. Every column earns its place; nothing is there for completeness.
| Column | Why it is there |
|---|---|
| Date | So a month of lines can be counted as a month. |
| Shift | Third shift finds out fast if it owns half the downtime. So does first. |
| Machine | The name the team uses, not the asset tag. "Mill 2," not "CNC-0047-B." |
| What happened | One line, plain words. "Spindle drive fault, would not reset." |
| Reason | A category from a short list, not a story. This is the column that makes the board countable. |
| Minutes down | The only column that turns into money. A board without it cannot be added up. |
| Fixed by | So the fix has an owner and the next person can ask them. |
| Still down? | Yes or no, so the next shift walks in knowing. |
Reason categories that work for most small shops: waiting on parts, no one free to run it, mechanical failure, electrical failure, changeover or setup, tooling, quality hold, other. Eight is plenty. More than ten and the team starts guessing.
The three mistakes that make it useless
No minutes. "Mill 2 down again" with no duration is a complaint, not data. If the team will only fill in one number, make it minutes down. Everything else can be reconstructed. That one cannot.
Reasons as stories. "Hydraulic line let go because the fitting was cross threaded from last time" is a great note and a useless category. The note goes in What happened. The category is Mechanical. Categories are what let you count.
Nobody reads it. The board needs a reader with a day. On Friday, whoever runs the shift takes ten minutes. Add up the minutes by machine and by reason. Say the top one out loud at the huddle. That is the whole ritual. Skip it for three weeks and the board dies.
Turning minutes into money
Minutes down become dollars with two numbers the owner already knows: what one person costs per hour all in, and what a machine earns per hour after material. Minutes times people standing around times their rate, plus minutes times the machine's hourly profit for the work that is gone for good. That is the honest version, and it is smaller than the numbers most vendors will show you, because it does not count the same dollar twice.
If you want the math done for you, the free downtime cost calculator does it in two minutes with every formula shown. Put a month of board totals into it and you will have the number that gets a Preventive maintenance budget approved.
Whiteboard, spreadsheet, or software
Honest answer: start with whatever the team will actually write on.
- Whiteboard or paper wins on the floor. Nobody has to log in. It loses the moment someone erases it, and it cannot add itself up. Print the sheet below, keep the old ones in a binder, and do the Friday math by hand.
- A spreadsheet adds itself up. The Downtime & OEE Tracker is this board as an Excel file: same columns, plus a dashboard that ranks machines and reasons in minutes and dollars, updated the moment a line is typed. $12, once, no macros. Want to try it free first? Get the free downtime sheet.
- Software makes sense when more than two or three people need to log from the floor at the same time and someone wants a phone notification when a machine goes down. That is a real need in some shops and not in most. The page on MaintainX alternatives does the per seat math out loud before you sign anything.
A breakdown board is eight columns and a Friday habit. Minutes down is the column that matters; reason categories are what let you count; a weekly reader is what keeps it alive. Start on paper if that is what the team will use. Move it to a spreadsheet when you are tired of adding by hand. Buy software when three people need to log from the floor at once and not before.
The free printable
One page, landscape, sixteen lines, the eight columns above, reason categories printed along the bottom so nobody has to remember them. Print a stack, clip them to the board, file the old ones.
