Resistance is futile. You will be assimilated by SAP!

One thing about SAP that distinguish it from other applications is the way it position itself. Call it the German stubborness or arrogance. But one thing is for sure. SAP changes you. Not the other way round.

SAP consultants will repeatedly through the use of the word "Best Practices" try to convince you to change and follow the SAP processes. So, if you're use to be doing something i say 3 steps. Implementing SAP, might mean that you might have to do it in maybe 1 step, or perhaps in 5 steps. You see, there's no way in hell the consultant would want to write an ABAP program just so that they can customize SAP to be exactly like the way you run things.

Using SAP means that "YOU" have to change! Yes. Resistance is Futile. Prepare to be assimilated by the Germans! :)
