Efficiency is one of the top reasons to outsource.
Fail.
LOL
You didn't bother to read the article, did you? If you had, you'd have seen this:
"...As Steve shows at length, this greatly increased the managerial complexity of the project and almost certainly helps explain why the project ended up three years late..."
Sounds efficient to me....doesn't it you?
But, for the benefit of you low information voters, let me give you another example.
I bought my grandsons model airplanes to build as Christmas presents. They are made by Revell, an old and respected name in the business. According to the box label, the plastic parts were molded in the USA, the box was printed in China and....get this...the model was packaged in China.
Now...think this through and tell me how it's more "efficient" to make the model airplane here, then ship it halfway around the world to be put in a box and shipped right back. Those little plastic pieces crossed the entire Pacific Ocean twice before they ended up on the store shelf here in Texas.
