For job-shop owners, ops leads & production planners

The quarter is sold.How much of it can you build?

The order book says $412,000. What it doesn’t say is that one drawing was never released, one job’s material was never ordered, and another’s arrives four days before a two-week build. This gate grades every line on the fundamentals and reads the book the way the bank would: what share of the booked dollars is actually buildable — and which order crosses into the next three weeks still on paper.

01.The Problem

The ERP shows orders. It doesn’t show jobs.

$127,700

Of the sample’s $412,000 book that isn’t buildable today — $66,200 of paper orders and a $61,500 material race. Thirty-one cents of every booked dollar is a hope, not a job.

$8,200

The order that forces the verdict: unreleased drawing, material never ordered, promising to ship in seven days. The smallest line on the book is the most dangerous one on it.

6 days

The slack on the $61,500 job — material due six days before a promise that needs fourteen of production. The PO says on-time. The calendar says race.

02.See It Work

Nine orders, $412k booked, one verdict — live.

FIRED — SO-5512
SO-5512 promises to ship inside the next three weeks and is not ready to build. The far-out book is allowed to be hopeful; a paper order shipping Tuesday is the verdict.
Verdict
SELLING WHAT YOU CAN'T SHIP
Fix first
SO-5512

Try it: release SO-5512’s drawing and cycle its material to ON HAND — the gate moves to SO-5534, the routing that was never released. Fix that too and the verdict falls to BOOKED ON HOPE with fix-first on the biggest dollars you can’t build: the $61,500 material race.

Same math as the engine and the workbook — byte-for-byte, evaluation date pinned identically in all three. Nothing here is scored by AI, nothing leaves this page, and the verdict will not soften because you wanted it to.

03.What’s Inside

A book read you can run before the production meeting.

The engine is zero-dependency Python — eight columns per order, a pinned --as-of date, and it prints every order’s verdict, the dollar-weighted book read, the gate, and the one order to fix first. The workbook reproduces the identical math, and the demo above runs the same logic. This is the engine’s verbatim output on the shipped sample:

VERDICT: SELLING WHAT YOU CAN'T SHIP
Fix first: SO-5512
04.The Standard

Built so the verdict can’t be negotiated.

Dollar-weighted, like the bank

The book read is the buildable share of booked dollars, not a count of orders — five small ready jobs don’t offset one large paper order. ORDER BOOK SOLID at 90%+, BOOKED ON HOPE at 60%+, SELLING WHAT YOU CAN’T SHIP below.

Slack, not arrival

Material due four days before a two-week job is a MATERIAL RACE even though the PO says on-time. READY TO BUILD requires the material to land with your production margin to spare — the margin is the difference between a plan and a sprint.

The red zone is absolute

A paper order shipping in October is a planning problem; a paper order shipping Tuesday is the verdict. Any non-ready order inside the window — already-late included — forces SELLING WHAT YOU CAN’T SHIP, worsen-only, releasing the moment it’s ready or honestly re-dated.

05.What This Is — And Isn’t

A buildability read, not a sales report.

It is
  • A deterministic, offline read of eight columns per order against a pinned date — engine, workbook, and demo produce the identical verdict from the identical book.
  • The cross-check your ERP won’t run: it happily displays a booked order with an unreleased drawing and unordered material as if it were work.
  • A weekly discipline: the runbook installs the buildability check at booking, the red-zone watch, and the honest re-date instead of the quiet slip.
It isn’t
  • An ERP, a scheduler, or an MRP run. It reads a log you fill in twenty minutes; your systems execute the fixes.
  • A sales review. It grades orders, never the person who booked them — booking work is the job; letting it cross into the red zone on paper is the failure.
  • Financial advice. The dollar figures are your own entries; contractual commitments and documented procedures override this tool — full stop.

Scope note. This tool grades order buildability from a book you enter — it scores orders, never people, and it modifies nothing in your ERP. Dollar figures are your own entries and the verdict is an operational read, not a financial statement. Contractual commitments and documented procedures override this tool. Not financial advice and not legal advice.

06.Who It’s For

Anyone whose backlog is measured in bookings.

Job-shop owners whose quarter looks sold until the expedite fees start

Production planners who find out at kitting that the material was never ordered

Ops leads who want the Monday meeting to open with one dollar figure and one named order

Owners preparing for a lender or buyer who will ask exactly this question about the backlog

Shops where sales books the work and the drawing release happens 'when engineering gets to it'

Teams inheriting an order book and needing an honest day-one snapshot at a pinned date

08.Common Questions

Straight answers, before you pay.

Every open order against the fundamentals: the three releases (drawing, routing, tooling) and the material position (on hand, on order with a due date, or not ordered). Per order: READY TO BUILD, MATERIAL RACE, or PAPER ORDER. The book verdict is dollar-weighted — the buildable share of booked dollars — because five small ready orders don't offset one large paper order, and the bank reads it the same way.
