Some time ago I learned from one of our collaborators with wide experience in the field, that the implementation of an ERP system degrades; in other words, in this case, too, the entropy law applies! His statement has caught me by surprise because the ERP implementation was not a piece of cheese left in the fridge left there to rotten. Although I had an extensive experience in the field, I haven’t had the time to think about this, because each time I finish an implementation I pass to another and so on until the final victory.
