I am a long time Baan fan and administrator. For nearly a decade I earned a living with Baan. But the joke goes like this:
Baan is (!) the number 1 ERP in the world considering the ERP market of serial manafacturers with around 90 to 92 users and branches in at least 3 countries, etc. etc.
If ýou define the market correctly (and keep redefining it narrowly enough) everybody is the world leader in it's field.
