It's PDI+ season again at the printer repair outfit where I work. About a year ago, I passed the witless multiple-choice exam and got it behind me. Two of my eminently capable colleagues weren't so fortunate, and they have to resit the exam. (For the whole back-story to this, see this
blog page.)
A new development has been the appearance of an outfit known as "
Killtest" that supplies a huge set of genuine sample questions with answers, so candidates can 'study' what they'll be 'tested' on. (This is surely an example of fleas on fleas.)
My contempt for all this has migrated from merely enormous to boundless. This is rot. This is rubbish. This is unbecoming to a race of 'intelligent' creatures. It all needs to be run through an industrial shredder and buried in a very deep hole in some very solid rock. I'll try to elaborate here on what makes me so contemptuous of it all.
The whole 'train/test/certify' paradigm is a worthless charade. The training material is shallow stuff with about the density of hydrogen -- it's a mile wide and a millimetre deep. The multiple-choice exam format is not a test of useful knowledge, unless you consider disconnected scatterings of trivia to be 'knowledge'.
'Studying' for a multiple-choice examination is to 'learning' what dumpster-diving is to food shopping and preparation. Study for multiple-choice examinations amounts to accumulation of factoids -- that's all.
The whole notion of 'training' presupposes that people are resistant to learning -- that they must have learning forced upon them, much like a puppy's nose might be rubbed in its own shit as it's housebroken. That is vile nonsense.
So do I have anything constructive to offer? I knew I'd be asked that, and I've come prepared.
Let's begin with what I, as a technician, am obliged to bring to the job. I'm obliged to be literate and numerate, and to be knowledgeable about the fundamentals of the technologies employed by printers. I should be able, for example, to use a digital voltmeter to confirm the operation of a photo-sensor, or an ohmmeter to confirm an open thermistor. Many technicians are not conversant with such rudiments, and PDI+ does not address them. I find that bizarre. I could help with such things on my printers blog, but there is absolutely no one who'll pay me a cent to do that.
I am
not obliged to have been born knowing how to gracefully dismantle any machine ever made, or to be able to intuit the meaning of any error code. Those things are the obligation of the manufacturers to document, and they do an appallingly poor job of it -- all of them, across the board.
What passes for service documentation in the printer service field is utter tripe. Access procedures are often overly illustrated, to the detriment of clarity, oddly enough. Simple procedures that in fact consist of nothing more than removing a few fasteners are made to appear complicated. Error code listings are riddled with either unhelpful 'information', or outright misinformation. Parts breakdown drawings verge on incomprehensibility. (HP's are the worst.) It's all a blight on the industry. The manufacturers have the resources to clean up that act; I don't, and it's not my job. But the failure of the manufacturers to do their job makes what
is my job far more difficult than it need be. Again, I could help with that on my printers blog, but there is absolutely no one who'll pay me a cent to do that.
I could go on here, but I've had about enough of this topic, and I have better things to do. As far as I'm concerned, PDI+ Certification isn't worth the powder to blow it to hell. It's a store-bought credential proclaiming one's fitness to function in a service industry that's a shambles and a disgrace.
Best of luck with your exams guys, and give my regards to CompTIA.
