Well having worked for the government in an ancillary security role about 20 years ago on contract, I don't think they could produce a parody notably worse than reality to use as a contrast. Today, I suspect it is worse.

Hire an expert they said. From the pool of experts they had heard about through contacts in the civil service. None of whom have any industry or real world experience. At best, someone was on an industry eating and drinking with the right people panel. I was there for 3 months and crawled back to my previous job cap in hand, bruised and educated.

It was long enough ago that I can away with rounding errors of months on my CV thank goodness...

It is worthy of note that most of the incidents in Yes, Minister were based on things that really happened. At some level it was more curation than invention.
