On the bright side, him and most others like him get caught. It's not as though the system is broken and open for abuse. It can just take longer to figure out that abuse is happening.
Much of this is a direct result of downsizing and the various strategic efficiency projects over the years. Fewer layers of bureaucracy are great for effectiveness and productivity, but the downside is that it concentrates responsibility for execution into fewer hands. Supervisors for many functions either don't exist or don't have the capacity or time to manage all elements of their responsibility, so a smart, experienced and slimy staffer can run amok for a period of time without his bosses knowing something is amiss. Spot checks, attention to detail (although, good luck) and a formal audit process are the best defence these days.
If you are claiming procurement has a lack of bureaucracy, I disagree.
I've seen the supply system open up to untraceable abuses specifically because further layers of bureaucracy were added.
It comes down to the direct supervisors not the levels of middle men above. If the direct supervisor is doing his job, he would have been approving each and every purchase this individual made. However, since the supervisors are busy creating reports and filling out paperwork to justify routine purchases to people so isolated from daily operations they barely comprehend what's in them in the first place, the supervisors don't have as much time to do their jobs.
I expect the outcome of this is going to be yet another level of "checks and balances" that will take ever more time from the local supervisors, further isolating them from the day to day, making it easier for the corrupt to obfuscate purchases of this sort.
This wasn't caught by a high level of bureaucracy in puzzle palace, this was immediate supervisors finding time to look into his purchases and start asking questions. No level of paperwork will replace an attentive supervisor. Paperwork is fake-able, eyes on the ground, not so much. It doesn't matter how much of a paper trail you build, if the immediate supervisor is not doing their job you can't be sure the paperwork reflects reality and at that point it's useless time and resource suck. Either you can trust the people on the ground or you can't. If you can't no amount of paperwork will fix that.
Also, seeing as kit I needed in 2015 that was cancelled 3 months before the deadline due to lack of time, which was re ordered on the 1st of April 2016, has been cancelled yet again by SSC, I don't see how you can claim procurement has a lack of bureaucracy.
We've got too much and it's impacting operations. those at the high end of the CoC who think more paperwork and bureaucracy can fix everything need to consider it's only as reliable as the people churning it out.
