manufacturing/inventory module

Hi i know inventory very well but not manufacturing. my question is: can we implement (setup, custumize,deploy) the inventory module in Navision without taking into consideration the manufacturing module, than when finished we start with manufacturing. Or it must go in parrallel so we had to know manufacturing basic needs to take care in inventory module, from the begining. thx

So long asw you follow the Navision development rules, you can do it this way. But if you bend the rules, then you may pay for it later when you go to phase 2.
