To customize or not to customize, that is the question. When you see a complex business process far from the standard ERP system, a knee-jerk reaction is to reach for customization tools and do the development.
Many ERP theorists say that ERP is only as good as it is an exact match for your processes. And they are mostly right about it. But majority of ERP systems are very generic (Microsoft Dynamics NAV included), and to exactly match your processes, they require customization. When it doesn’t work out-of-the-box, you customize it, it’s that simple, isn’t it?
It’s not, sorry.
