How the Post Office's Horizon system failed: a technical breakdown

"From bugs to unqualified staff, the Post Office's point-of-sale system was inadequate on many levels."


The code was poor from the start and the small team of developers were not up to the job. However, the problems were apparent in 1999 before it was launched.


Includes a discussion of the Dalmellington Bug, the Callendar Square bug, and how the integrity of the system was unreliable given that Fujitsu employees could have unaudited access to the Horizon database.
