Readers may be interested that Britain's joint armed forces pay system, part of JPA (Joint Personnel Admin) is also recognised to be something of a clusterfuck (although not quite as bad now as it was back when it arrived), dragging in its wake myriad unlucky sods who found themselves paid incorrectly and struggled to get anything fixed, including an RAF chap who ended up simply suing the MOD for the money they owed him but found themselves unable to actually give him. JPA was put together principally by the no-longer existent EDS, whose reputation for being able to handle large complex systems is well known in the industry. It's worth mentioning that in the industry, smart cookies recognise that payroll is very much a wicked problem, and payroll for something as complicated as the armed forces is massively complex. Less smart cookies do not recognise this and routinely massively underestimate the work involved and the support required.
