Great British Software?
Since we are now free of EU regulations on competition for public sector contracts, and have a Westminster gummint which is powerful enough to drive through whatever it likes ... how about having a bash at mandating a standard spec for how UK councils need to operate, and financing a bespoke software system to deliver precisely that spec via a new dedicated and publicly-funded provider - without using any of the big commercial platforms?
I know, I know - public sector IT projects always go wrong. But that's largely because the development / customisation is not public sector at all - and the local council wonks who commission them have no idea how to write a specification, because that requires a high level of technical skill which is way above their paygrade.
Local councils may all think they want a different thing, and Dr S is quite correct that Oracle and SAP are anxious to "help" them develop that thing - but I always thought that the USP of SAP/Oracle is that they are global-scope systems with specialists who can implement localisation. That makes them a great fit for Global Multinational (& Lunar) Solutions Inc, who need to run HR systems (and dodge taxes) in 25 different jurisdictions, but a lousy fit for North Scruttockshire Borough Council. OTOH the latter's requirements are pretty much exactly the same as those of South Scruttockshire Borough Council, so it makes sense for them to share the cost of developing and using the same system. It's axiomatic that those who use off-the-shelf systems (whether customised or not) only use a tiny portion of their functionality, but still have to pay for all the functionality they aren't using. Bespoke, ground-up design can often deliver bettter value.
So a UK-based development program could develop a UK-specific software spec for UK councils, as mandated by the UK government, and get that spec implemented by setting up a non-profit (but still very well financed) software developer to build the thing from scratch - ideally using only FOSS for its backend so with no licencing overhead (apart from all the users being welded to Windows / MS Office, which from my own experience appears to be insurmountable whatever the cost). It would have to be done in an Agile sort of way, because even with a mandated spec the goalposts will be mobile - but at least that won't involve negotiating new contracts with billionaire-owned software houses based abroad, as it does at the moment.
And who knows - if that works out, perhaps the same organisation could do something similar for parts of the NHS, the MOD, and all the other IT moneypits into which we keep pouring massive amounts of tax dollars and getting sh*t that doesn't work in return.
