Tuesday morning, one email: your only supplier of a critical part is twelve weeks late.

  1. 1The Email That Stops a FactoryFree06:40 on a Tuesday: your only supplier of a critical part says twelve weeks. Here is the arithmetic that turns those words into 440 unbuilt ovens, and the eleven desks it is about to cross.7 min · quiz includedStart →
  2. 2The COO: What Are We Actually Optimising?FreeAt 07:15 Ravi Menon has the Vantor email and about an hour before ten desks start improvising. His first job is not a plan — it is deciding, out loud, what Calder Thermal is optimising for.7 min · quiz includedStart →
  3. 3Procurement: Is There Another Source?FreeHannah Wolcott has three days to run every alternative supply of the CB-40 to ground — and the hardest part of her job is telling Ravi honestly that none of them arrives in time.7 min · quiz includedStart →
  4. 4Engineering: Can We Design Around It?FreeFourteen weeks to design out a chip, against a twelve-week disruption. Dev Anand explains why the obvious fix cannot rescue this crisis, starts it anyway, and gives everyone else answers firm enough to plan against.7 min · quiz includedStart →
  5. 5Allocation: Who Gets the Boards?FreeTomasz Nowak has 520 control boards and firm orders for 960 ovens. He is not solving a puzzle with a right answer — he is choosing, by name, which customers get disappointed.7 min · quiz includedStart →
  6. 6Manufacturing: What the Plan Costs on the FloorFreeTomasz's allocation is optimal on a spreadsheet and expensive on a production line. Grace Okonkwo prices the changeovers, decides what to do with sixty-eight people who have no boards to fit, and sends the plan back with a counter-proposal.7 min · quiz includedStart →
  7. 7The Analyst: Which of These Orders Are Real?FreeTomasz has allocated 520 scarce boards against 960 firm orders. Yusuf Rahman's job is to find out how many of those 960 are firm at all — before boards are committed to demand that was never there.7 min · quiz includedStart →
  8. 8Finance: Lost Revenue, or Just Late Revenue?FreeClaire Beaumont has to tell the board what this costs — and the answer turns on a distinction nobody in operations has made: money that is destroyed against money that has merely moved into a later quarter.7 min · quiz includedStart →
  9. 9Sales: Which Customers Do We Protect?FreeThe protected list needs 521 boards and Calder has 520. Marcus Reid cannot add a customer without taking one off — so he stops ranking by order value and starts ranking by which losses are permanent.7 min · quiz includedStart →
  10. 10Customer Service: Delivering the NewsFreeMarcus has decided who gets protected. Siân Pritchard has to turn that decision into four hundred conversations in a fortnight — and how those conversations go changes the commercial outcome as much as the allocation did.7 min · quiz includedStart →
  11. 11Risk: Why Could One Supplier Do This to Us?FreeNobody at Calder was negligent, and that is precisely the problem. Ingrid Sørensen reconstructs how two sensible decisions built a six-year single point of failure, and brings the board four controls instead of the twenty it expects.7 min · quiz includedStart →
  12. 12The Reckoning: What It Cost, and What ChangesFreeTwelve weeks on, Eleanor Vance gives the board an account: 370 ovens undelivered, $4.7m of revenue moved or lost, $700,000 spent — and the one line on that page that decides whether Calder is safer next year or merely poorer.8 min · quiz includedStart →
