IT Management in itself is a merry mix up of two disparate fields the Information Technology (IT) field of discipline and Management itself. We can say that IT Management is the management of the various systems in an IT master system. Since the two fields are individually complex already, to manage both is quite difficult and requires specialized training too. Thus we have IT Management Service Training nowadays as well, which is the ability to render service when IT Management is a priority or when IT systems under management fail on us.
It seems ironic that such expensive investments like IT systems are prone to system failure when less costly business investments like, say, a doorknob for your office do not. But IT systems are quite delicate systems so even if your doorknob can absorb abuse when you slam your door in a fit of rage, your IT systems like the CPU of your desktop PC cannot absorb that type of abuse and will exact their revenge by never working for you again immediately afterwards.
IT systems are also prone to attacks from malicious people who may feed your IT system with damaging information like PC parasite programs and viruses, so that makes the job of an IT Management specialist much harder. This is why it is never advisable to share sensitive data about your IT systems with other people (especially passwords and even user ID s) because you may be inviting trouble if you do so (and if someone successfully infiltrates your IT systems, no IT Management specialist can defend you until the damage has been done and the invader leaves the system.) IT Management service training can help you with simpler problems like hardware defects and the like IT Management service training cannot protect the users from their own imprudent acts.
