"OMG we're the government and everything we do is huge and unprecedented so it is impossible for us to use off-the-shelf anything and we can learn nothing from best practises" is step 0 of every failed big government project.
There's significant thawing of that attitude (and gov.uk, for their imperfections, is definitely a very positive part of the trend) but the idea is alive and well.
Yes because a real world organization with IT systems going back 50+ years is exactly like some me to macbook and MBA start up with two men and a pantomime horse in old street.
Are you a price comparison site? Or Experian or Equifax perhaps?
Unless you clearly say you're not just some enterprise business that aren't exactly known for their technical competence this comment is totally ambiguous.
Do you just think you know what you're talking about, or do you actually?
You don't have to take my opinion seriously. I could work in Tescos and be splurging false information out on the Internet. I could be an elaborate hoax!
However, please don't write off people as "just some enterprise business that isn't exactly known for its technical competence" because we all know that startups get it right all the time as well...
As for do I know versus do I think, there is the third option do others know and that is all that is important when it comes to getting paid...
So you are handling a small set of related services to a large number of people. That's hardly comparable to the task of migrating 300+ (distinct) government agencies/services to the new system, along with whatever old systems they currently use.
