More than 20 years ago, the Japanese technology conglomerate Fujitsu created an accounting software system for the UK Post Office. ‘Horizon’ was rolled out to branches across the country, often small, independently run shops that collect and deliver letters and parcels to tens of thousands of people. At the time, it was the largest civilian IT project roll-out in Europe. Horizon was troubled by errors, a phase familiar to any user of a new IT system. Except, these were not small bugs. In some cases, the Horizon IT system told members of staff that they were not depositing enough money at the end of a day’s trading, leading to the ‘loss’ of thousands of pounds every night.
