existentialist
Tired and unemotional
This is the bit that appals me. Someone, and probably lots of someones, must have been thinking "hmm, new system, and all of a sudden we have an apparent massive fraud problem...could these be linked?"It’s quite a jump from “supplier defending their product” to “let’s send the users to jail”.
The post office were the prosecuting body and should have been hugely more sceptical about their fundamental hypothesis which appears to be “we’ve done a huge IT systems change and now lots of our staff are stealing from us so we should send them to prison”
Chances are that a lot of the devs and test people probably were thinking that, but the minute it got upstairs, that was discounted. Especially if the supplier was happy to ignore any dissenting voices, and the PO was happy to take the supplier's word at face value.
I'd like to think that this would be a salutary tale that caused a lot more people to be a lot more cautious about taking things on trust, but I'd bet dollars to donuts that they aren't.
