Just wondering....is the SAP software HEAVILY CUSTOMISED?
Once upon a time, in a land far away, a huge retail organisation bought Peoplesoft and then had it HEAVILY MODFIED. For the next ten years, it was almost impossible to apply any patches issued by Peoplesoft. Duh!!
Then -- when the penny dropped -- said huge retail organisation paid a fortune to RE-IMPLEMENT the latest version of Peoplesoft with NO MODIFICATIONS.
Guess what.....huge consultancy bills at the beginning, during the ten year life of the modified sotware, and during the conversion back to "standard".
Why am I not surprised?
