IT in Support Quadrant of McFarlan's Strategic Grid
Over four decades ago the IT/computing/data processing drive was to develop an IT hierarchy and knowledge/experience base whereby the top IT level were fully conversant with business issues, impact etc - were business men with extensive wide ranging IT knowledge and thereby able to support, design, install progressive effective IT.
Outsourcing of IT amongst other things has
led to IT being a low level tasking operation with unvalidated/poorly validated output/installations, lack of challenge and intellectual input to the end result. So IT is now definitely in the low quadrant.
Similarly databases were introduced in early 70s but current IT functions seem to have inability to understand, modify, integrate legacy systems system.
