Computing = to determine especially by math calculation, which is (or should be) only a small fraction of what the MIS/IT departments do. To me, the most significant activities of MIS are the analysis of systems, then the design of new systems. It‘s true that in the beginning the ‘computing department’ was merely a way to do math calculations faster and more efficient, but today the department has its fingers in all activities of a company from management, to operations, production, accounting, HR, etc. BTW, how do you justify HR replacing ‘Personnel Department’?
So, I don’t see why IT is better than MIS, but ‘computing department’ is oversimplifying to me.

>>This morning we got the news that our department's name will change from MIS to IT, the reason being that MIS is outdated. I don't have any statistics, but it seems IT is more common.
>>Can anyone comment on the proposed change - i.e. good/bad idea, (in)significant, other thoughts?

>The frequent name changes are confusing. When I first read about "MIS", "IT" and "IS", I thought there was a whole new science involved. Actually, it could all just as well be called the "computing department".
