Get the One Step Out of Your Head and Onto One Page

The problem in one breath

Every crew flashes a chimney a little differently, and half your callbacks are chimney leaks. The right way is real — you've done it a thousand times. It just lives in your head, or your best foreman's, and nowhere else. So it only comes out right when one of you is standing on the roof.

Why it happens

You know the step cold, so it never seemed worth writing down — it's obvious to you. But obvious-to-you isn't the same as taught. A new man can't read your hands. The know-how sits in one or two heads, and the day one of those heads is home sick or quits, the step walks off the job with him. That's the callback nobody saw coming: not a lazy crew, just a right way that never left your skull.

The play

Don't document the whole company. Find the one step that swings on who's running it, and get that single step onto one page anybody can follow.

1. Find the step that changes depending on who does it. Look at your callbacks. The detail that keeps coming back — the chimney flashing, the tear-off order, how the final walkthrough goes — is the one trapped in somebody's head. Pick that one, not ten.
2. Write it the way you'd say it, on one page. Give it a plain title — "How we flash a chimney here." Then the handful of steps in order, in words a guy actually uses. Number them. Not a binder nobody opens — one page a man reads standing at the truck.
3. Mark the two or three spots guys get wrong. You already know where it goes sideways — the ice-and-water that stops short, the course started on the wrong side. Call those out right on the page: "This is where it leaks if you rush it." The warnings earn their keep more than the steps do.
4. Show what "done right" looks like. One line, or better, a photo of the finished detail they're aiming at — so a man checks his own work before he climbs down. A picture lands faster than a paragraph. Snap the good one and put it on the page.
5. Do it in front of them once, then watch them do it. Paper alone won't transfer it. People copy a move they see far better than one they read — so hand out the page, run the step live, then watch them run it back (that's watch me, then I watch you — M3-04). The page is the reminder; the showing is the teaching.
6. Keep it where the work is, and keep it current. The page rides in the truck, the job folder, or on their phone — wherever the guy stands when he needs it. A sheet in a filing cabinet trains nobody. And the day you find a better way, fix the page — it's a living sheet, not a monument on the wall.

Do this this week

Pick the single step that causes you the most callbacks — the chimney, the tear-off order, the walkthrough — and write it on one page: a title, the steps in order, and the two spots guys get wrong. Just that one step. Don't touch the rest of the business. Twenty minutes, one page, and the standard is out of your head for good.

The tool

No spreadsheet — one page you print and fill in, one per step. Staple a photo of the finished detail to it when a picture says it faster than your words do. Keep a blank stack in the truck so the next step you catch trapped in somebody's head gets written down on the spot:

HOW WE DO IT HERE   —   one step, one page

How we ______________________ here
   (e.g. flash a chimney · run the tear-off · do the final walkthrough)

The steps, in order:
   1. ____________________________________________________
   2. ____________________________________________________
   3. ____________________________________________________
   4. ____________________________________________________

Where guys get it wrong (the callback spots):
   •  ____________________________________________________
   •  ____________________________________________________

Done right looks like: ________________________________
   (one line — or staple a photo of the good one here)

Found a better way? Fix this page — don't file it.

If your crew is 1099

Careful here — this is the same control problem as watch me, then I watch you (M3-04); that's the play that spells the whole warning out, and it says who to ask about where the line sits. Writing down exactly how a step gets done and then drilling a sub's men on your method is direction, not a spec. So with a subcontractor the page never goes to his crew — it goes to his company as the finished result you're buying: "step flashing woven in course by course, counterflashing cut into the mortar joint, ice-and-water a course past the chimney, no exposed fasteners." How his men get there is his to run. The page still earns its place: for your own W2 crews, and as the language you hand the subs.
