My workplace sent me to an ITIL v3 foundation course, and I had 3 days of being taught the syllabus, followed by an exam. Technically, we had 2 and a half days of being taught, as the exam was on the afternoon of the 3rd day. Now, let me tell you why I hate ITIL.
I started out as an IT Technician. I'm a technical guy, and anyone who is technical knows that we have to follow a logical thought process to try and solve a problem. Let's say that a computer is blue-screening - well, we'll check the error code, check RAM etc etc We'll try to logically find the cause of the fault, then fix it. ITIL and the managers who take it (from what i've seen) use ITIL as a way of trying to prove they're intellectually superior and that the guys doing the technical work need to meet often ridiculous SLA's. It could even be argued that managers with ITIL don't see the hard work and knowledge a technical person requires as they just care about targets they need to meet, thus driving down/keeping down wages of techies.
Roadblocks
Fast forward a few years from my IT Technician days and I now work in the Digital Security field. Now, this place follows ITIL to the letter. Everything in the workplace is ITIL. I can tell you hands down it was the worst place i've ever had the misfortune to work in. Why? Because ITIL makes everything so damn slow. What do I mean? Let's take a CAB for example. I've got a firewall change I need to do. As anyone worth their salt knows, a firewall change should be done VERY quickly. A CAB slows down the process. It acts as a large roadblock. ITIL people will tell you "it's there to help" - but regardless of what it's "there for", it slows things down - which is bad...obviously.
Firstly, you have to get a hold of everybody on the CAB, which means emails get sent around, everyone has to accept and attend the calls at the right time. Things can get declined on CAB !!! Which means your firewall change wont be accepted immediately and hence, the roadblock.
Acronyms
My manager(s) would reel off the names of ITIL acronyms to all of the staff, knowing that the staff hadn't been trained on ITIL. The amount of acronyms within ITIL is ludicrous and serves as nothing more than an annoyance. If your manager emails you (because mine never had the decency to actually approach you) and says: "Can you look at the CMDBs and the SKMF? We'll have an ECAB if we need to because the SRM isn't around".... It's just a joke.
It says a lot that Axelos have a 70+ page pdf explaining such acronyms:

I could go on. All in all, this course/cert was the pits. Does anyone agree?? Or am I the only one who sees through the marketing BS/hype around this cert?
