Initially I replied thinking you were talking about getting training in a specific set of tasks or platform, you mentioned "Product X".
But it seems, now you're talking about training a worker "to productivity", which is a bit more oblique and not as specific of a regimen against what you initially posited-on this I have somewhat of an easier time giving you the concession.
Let me just ask, before going further: which position are you taking? Training an employee to use a specific tools set that we've established isn't widely used, or training an employee to be most effective and productive day to day?
Or have I misunderstood you altogether?
