100 Fun Facts About Supply Chain

Which fashion chain is famed for taking designs from sketch to shop in as little as two weeks?

Zara sends its clothes through its distribution centres in Spain and ships to stores twice a week in small batches, so a look that sells can be restocked while it is still in fashion.

In April 1956 the converted tanker Ideal X made a pioneering container voyage from Newark to which port?

Houston had 58 trucks waiting, one for each container on board; the voyage was the idea of Malcom McLean, a North Carolina trucker turned shipowner.

McLean's container line, originally Pan-Atlantic Steamship, was renamed what in 1960?

Sea-Land Service made Malcom McLean rich: R.J. Reynolds, the tobacco firm whose cigarettes his trucks once hauled, bought it in 1969 and he made $160 million.

Which engineer, hired by Malcom McLean, designed the twistlock and corner castings that lock shipping containers together?

Keith Tantlinger developed the twistlock in Spokane in the 1950s, and his corner fittings became an ISO standard, so any crane, truck or ship in the world can grip any box.

Container ship capacity is measured in TEU, in which the T stands for what?

Twenty-foot: the unit counts every box as if it were 20 feet long, so a standard 40-foot container counts as two and a ship's capacity can be given as a single number.

Why is the smaller standard shipping container an inch and a half shorter than its nominal length?

So two fit under one 40-footer: twistlocks hold a pair of the shorter boxes 3 inches apart, and trimming each one makes the pair exactly as long as the big box stacked on top.

Most shipping containers are made of which steel, prized by sculptors for its orange-brown skin?

Corten steel, also called weathering steel, forms a stable layer of rust that shields the metal beneath and slows further corrosion.

In March 2021 the container ship Ever Given blocked which waterway for six days?

The Suez Canal was shut for six days; Egypt then impounded the ship for three months while demanding a reported $916 million, including $300 million for 'loss of reputation'.

In 2021 the Ever Given flew Panama's flag for a Taiwanese line, but its owner was from which country?

Japan's Shoei Kisen owns the ship, so the compensation claim after it ran aground fell on the Japanese owner and its insurers, not on the Taiwanese line that chartered it.

What finally helped free the container ship stuck for six days in 2021?

A spring tide under a full moon lifted the hull while tugs pulled and dredgers sucked sand from around the bow.

De Lesseps was a diplomat, not an engineer; his sea-level plan for Panama collapsed amid malaria, yellow fever and financial ruin.

Which Egyptian leader nationalised his country's main canal in July 1956, triggering an international crisis?

Gamal Abdel Nasser seized the British- and French-owned canal company on 26 July, a week after Washington withdrew its offer to help pay for the Aswan High Dam.

The locks of the Panama Canal lift ships 26 metres up to which artificial body of water?

Gatun Lake was the largest artificial lake in the world when the Chagres River was dammed in 1913; ships sail across it, which spared the builders a vast amount of digging.

Which country took over the Panama Canal project from France in 1904 and opened it in 1914?

The United States bought the French works for $40 million, finished the canal and ran it for most of the century, handing it to Panama at noon on 31 December 1999.

Which two engineers developed the Toyota Production System between 1948 and 1975?

Taiichi Ohno and Eiji Toyoda built on an idea from Sakichi Toyoda's automatic looms: a machine should stop itself the moment something goes wrong.

Waste comes in seven classic kinds in Toyota's system; overproduction is called the worst, since making more than is needed breeds several of the others, from excess stock to extra handling.

The kanban scheduling system takes its name from the Japanese word for what?

Signboard: the 'signs' are cards that travel with each bin of parts, and a card coming back up the line is the only permission to make more.

Which WWII cargo ships were built so fast that one was launched under five days after its keel was laid?

Liberty ships were built from sections welded together, and American yards turned out 2,710 of them; the Robert E. Peary's 4 days 15 hours came from a race between shipyards.

Which 1961 book by Jay Forrester first described the bullwhip effect, also known as the Forrester effect?

Industrial Dynamics grew out of a puzzle at General Electric, where an appliance plant lurched between hiring sprees and layoffs; Forrester showed the firm's own rules, not the market, were to blame.

The 'beer game', a classroom simulation of supply chain coordination, was invented at which university?

MIT's Jay Forrester invented it at the Sloan School in 1960; players see only the orders passed to them, so a small bump in demand snowballs into gluts and shortages.

What was the first item ever scanned with a UPC barcode at a checkout, in June 1974?

Wrigley's chewing gum, a pack of Juicy Fruit, rang up 67 cents at a Marsh supermarket in Troy, Ohio; the shopper later said he picked it because no one had been sure a barcode could be printed on something that small.

Incoterms, the three-letter terms that divide costs and risk in trade contracts, are published by which body?

Break bulk cargo travels piece by piece in sacks, crates, drums and barrels; the name comes from 'breaking bulk', the old phrase for starting to unload a ship's hold.

McLean's line chose 35-foot containers to match the legal limit for what?

Highway truck trailers could be no longer than that on the roads its trucks used, so the box was sized to ride legally behind one; to McLean's frustration, the later ISO standard lengths left it out.

Which Apple executive, hired from Compaq in 1998, cut its inventory from months to days by closing warehouses?
