The training matrix
One card per man, one rung per skill: watched me do it, did it while I watched, taught it to next guy. Only the last rung counts, because a man who can do a valley but can’t teach it isn’t cover for it — when he’s out, nobody can bring the next man up. The page adds it up two ways: how many details each man can teach, and how many men can teach each detail — then flags the ones resting on one man or nobody, and names the man.
Free, and it asks for nothing. No email, no account, no sign-up. What you type stays in this browser on this device.
Read this first
This is the roll-up, not the training. The play ships a one-page training card that rides in the truck — one per man per detail, filled in on the roof as he climbs the three rungs. That card is the record of what actually happened. This page is where all the cards add up, back at the shop.
The eight details are a starting point, not a rule. Rename them to the things that cause your callbacks, and clear the ones you don’t run — an empty slot counts nowhere and never flags. And be honest on the top rung: a man is on it when he has actually taught the detail to somebody else, not when you think he could.
The matrix fills in right here in your browser. If this line stays put, JavaScript is off — the spreadsheet below does the same job.
How it gets used
- Run the play on the roof first. Fill in the man’s training card there, while it’s happening. Guessing at a rung in the office is how a skill ends up looking covered when it isn’t.
- Name your details before you name your men. Eight slots, same as the file. Tear-off and cleanup are on there because they get skipped; step flashing and pipe boots are on there because they leak.
- Set every man’s rung off his card. A card with all three boxes checked and a signature is the top rung. Anything less is the rung below it.
- Read the flags at the top of the page and pick one. Every flagged skill rests on one man or on nobody. Take one this week and run rung one on a second man — not all of them, one.
- Put the man you picked on a date. “Carlos learns step flashing on the Tuesday tear-off” belongs on the promise list with your own name on it — type it across, the way you would between two spreadsheets. Training that only lives here doesn’t happen.
- Bump the rung after each session. The flags clear themselves as the bench gets deeper. That, and not the number of men, is what makes a crew you can leave.

The same matrix as a spreadsheet
the-training-matrix.xlsx is this matrix as a spreadsheet — same three rungs, same two counts, same TRAIN THIS flag — for the computer at the shop. Four differences in the page’s favour: the flag names the one man a thin detail rests on, where the file can only print TRAIN THIS; a rung left under a detail you’ve since deleted doesn’t pad anybody’s teach-count, and a rung sitting on a row with nobody’s name on it doesn’t keep a skill out of the red (both of those make the counts stricter than the file’s, never looser — this page will never call a detail covered where the spreadsheet calls it thin); there’s no sixteen-man ceiling; and the example crew is gone, so there’s nothing to delete before you start. Three the other way: the file shows the whole grid at once, every man against every detail, which a phone cannot do and which is genuinely the better view on a big screen; it’s a real file, so it survives a cleared browser; and it opens on any computer you send it to. The sheets ask for your email once; this page never does.
The play behind it — M3-04 Watch Me, Then I Watch You — is the three rungs themselves and the training card that rides in the truck, and the sheet notes spell out every column, both counts and the flag.
