And yet, most IT will see it as an opportunity for locking down systems and policies, instead of the call for help shadow IT is: people want systems that are reliable, efficient, and adaptable to rapidly changing business needs. Providing them is part of the core mission of IT, and they're failing at it in some companies. One anecdotal example: I'm responsible for doing trainings at my company. If I see someone providing trainings on their own, creating their own class material, using their own platform... basically wasting company resources; I don't consider it shadow training but I take it as an indication that A. they have a need B. are very willing to work to achieve it and C. I'm not filling up that need properly, maybe not even communicating correctly about it. I take ownership and I don't play vigilante. When IT are providers, helpers to the employees, instead of self-appointed inquisition on a mission to purify the systems and its users, it works for the best.
