the leaders of sub-groups within the organisation making decision that affect the whole organisation based only on their sub-group's limited needs. This often results in a decision that is very harmful to the overall welfare of the whole organisation; and that's what happened in the 1980s. One sub-group got a set of PCs that best fitted their sub-group, while another did the same, and then they found out the two answers weren't compatible while another answer would have given them both a 95% fit and been better for the overall organisation. Today we're seeing a lot more of this "stuff the organisational needs, I want" attitude with the proliferation of mobile devices and BYOD - each person gets what they want and don't care how it fits with the organisation's needs or legal requirements. Cloud computing is very much the same way.

Any decision about IT MUST be made by someone who knows and understands the FULL technical, legal, and operational ramifications of what the changes will mean for the overall organisation. This very rarely happens when the decision is amde by a single unit head in isolation.
