I think that comment about OXY senior management thinking that "IT was not a competitive advantage" is very telling. I don't work in IT, and I certainly don't sit in the "inner circles" of OXY management, but I came to the same conclusion years ago.
Now think about it: For 30 years, successful companies have invested ever more into IT. That is because IT (when done well) provides enormous productivity. Those of you reading this, ask yourselves: Is your team spending a lot of time "monkeying around" with antiquated, systems, which require you to burn 2-3 times the amount of time you should have to spend, to spit out reports? What about when your boss needs some "new report" – one which our Dinosaur systems cannot easily be configured to provide? More time wasted/burnt.
[ One exception to this under-investment in IT, seems to be the incredibly stupid, non-user-friendly "goal-setting"/employee appraisal software which Human Resources seems to buy and then throw away every 2 years. Who is the numb-nuts in charge of their IT budget?]
Because OXY has chronically under-invested in IT, we are instead needing to retain a lot more headcount to massage these old systems. – So money is not being saved. If you buy one great IT system, that is one big check OXY has to write "up front". But by being cheap on IT, OXY instead has to pay ongoing excess compensation costs to retain so many more headcount to operate these antiquated systems.
Every "top level" decision made at this place is the wrong one.
