"Quite so but I reckon it's a pretty good description of what it needs to be."
TBH it was just my boiler plate for how to approach govt systems in large countries.
They're big. Don't turn up if you can't handle 10s of millions of records minimum (think size of a population over decades, or number of companies registered at Companies House, also over a decade)
The UKG IT system is "mature." Lots of systems sharing data. In the case of HMRC also data transfer to other countries.
Paradoxically they are also moving targets, changing as the legislation changes on the large scale, changing customs duties and taxes during a budget.
As was noted in a Raik presentation "At small scale anything can be made to work." True.
Live government systems are never small scale.
Biting the hand that feeds IT
