I'd to see teh business case in this exercise. Usually, you would find a partner who has the infrastructure, a track record, and a workforce. And your outsourcing costs are about more resources for same cost, or same resources for less cost.
Think about it; they pay the JWs next to nothing to print the material, but have to house & feed them probably at low individual cost. With outsourcing, the price will have to cover the labor costs, and other related overhead like insurances, etc. Is the global average cost of a JW print worker less than a fully-loaded Indian print worker? I don't know.
The other cost is all about machinery + ink + paper + distribution.
One could argue that the materials, if all purchased centrally in India, might be cheaper. Clearly that would make a difference given amount of paper they get through...
The machines should already be there, so there is (hopefully) no upfront investment to be made.
But the distribution cost is something that I'd question. Imagine how long it would take to truck or train loads of printed material around the globe? Or by boat? Surely that takes weeks? Air frieght is very expensive. Nobody would wait for the hard copy, they'd all be on-line at jw.org. (Maybe a driving factor, who knows?).
That's my own view. I have no idea how the WT operates its printing and distribution now. It could be a model that TNT, DHL or some other company would envy, or they could have outsourced it all to those guys already and they'll get such a good deal shipping from India they can't turn it down?
Oh, and not to mention the people you (still) need onshore still to ensure the offshore operation is working effectively and delivering as expected...
