I can see a company of 120 needing 5 more IT staff to effectively utilize Microsoft productivity infrastructure, but you would likely be able to either cut that employee count down to 100, or more positively, have the same 120 people handling the productivity of 150 employees, increasing your company’s output and profit.

More knowledge work is required to make effective use of the entire Microsoft stack, but in the enterprise, nothing comes close for multiplying user productivity.
