Too many people become enthralled in learning the technology they want to work with and seem to forget the purpose for the technology in the first place. Active Directory is great, and knowing how to setup, troubleshoot, and administer it is fantastic. But what's the reason for it? Centralized management, which allows for greater control and efficiency in the business. It's a problem of being taught facts without understanding the context behind those facts, and that's a problem that affects the job industry as a whole, not just IT, although IT is usually the field where it's most dramatically seen. People going for finance or business management understand that their tasks are to suit the business needs, and the skills they bring to the table are to serve that purpose. But IT seems to go down this rabbit hole that the technology is king above all else, forgetting what the purpose of the technology is in the first place.
