There is a difference between shops that use home-grown applications, or a mix of individually selected commercial tools, and those running ERP's like Peoplesoft and SAP.
Using home-grown or selectively purchased applications allows you to choose the processes that fit best with the goals you choose.
ERP's define the process by which you get to your goal, which requires you to choose your goals to fit the process, unless you are willing to undertake expensive and difficult modifications.
This is not unlike the difference between centralized command and control economies and market economies.
I am interested in seeing what Slashdotters think of this and what they think is driving demand for ERP's.
