Any supplier building capacity against a moving specification — defence, construction, platform deals: write down who freezes the design and when. A bet won on conviction still has to be run, and rework is billed whether or not it was priced.

In January 1940 Washington asked Ford to build wing sections for the B-24 Liberator. Production chief Charles Sorensen flew to Consolidated Aircraft in San Diego and found bombers assembled outdoors on steel fixtures — heat-warped, tailored, impossible to turn out two alike. Challenged, he worked the night at the Coronado Hotel, sketching on hotel notepaper a plant a mile long and a quarter mile wide to finish one bomber an hour — 'Unless you see a thing, you cannot simplify it.' Over breakfast, Edsel Ford approved a $200 million complete-aircraft proposition backed only by the pencil sketch.

The Albert Kahn plant — 975 acres, five million square feet, the biggest single industrial building of its kind — was dedicated in June 1942, and it nearly flopped. Ford's mass production assumed a frozen design; the army's designers kept changing the bomber, and the steel-cast dies made every change painful. The first Ford-built Liberator only rolled off the line in September 1942, and production only began in the final weeks of that year. Critics took to calling the plant 'Will it Run?'; in 1943 a committee authorised by Congress examined the problems and issued a critical report.

By April 1944 Willow Run was finishing one Liberator every 63 minutes, around the clock, with more than 42,000 people at peak. By The Henry Ford's count the plant delivered 8,685 Liberators — 6,792 complete aircraft and 1,893 knock-down kits — and the last one left on 28 June 1945. Charles Sorensen, who told the story in his memoir My Forty Years with Ford, ranked Willow Run 'the biggest challenge of my production career — bigger than any Model T assembly line sequence for Highland Park, more momentous than the layout and construction of the great River Rouge.'

Ford's mass production assumed a frozen design, but the army kept changing the bomber, so the plant spent its first year on rework until it hit one every 63 minutes.

The $200 million was approved over breakfast on a pencil sketch — real conviction, zero diligence, and no plan for what happens when the customer keeps redrawing the product.

Ford's method needed a frozen design; the air force had none. The biggest factory of its kind spent its first year converting rework into its main product.

Scale came before proof. The name 'Will it Run?' was earned in 1942 and only worked off plane by plane, two years later, at one every 63 minutes.

Conviction can finance a factory but not run it. Mass production needs a frozen design; when the customer keeps redrawing, the biggest plant becomes the slowest — and the gap is lived in public.
