There is a whole group of people who their job depends on the system existing like it does. One dude I worked with re-did a procurement system with a few spreadsheets. He got tired of waiting for 30 people to 'do it'. As soon as his boss found it the whole project he was on was scrapped and he was demoted shortly thereafter. His 'sin'? He had accidently found a way to put 30 people out of a job. These systems exist like this because our gov wants them that way. Not because they are the best. Yesterday should have been 'run this on these 2 old boxes and make sure they still work' regression test. Sounds like either that step is not there, totally skipped, or does not match reality. Building a real five 9s type system means taking each piece and pondering 'what are the different ways this can fail'. Then mitigating each of those. It is mind numbing tedious work than takes a long time to do. Also most of this is probably run by contract houses. Which means the people who use it do not really 'own it'. Which is by design, for CYA. Which costs more and takes more time because it is all paperwork.
