That is literally their purpose. Don't want to go through the hassle of offshoring your entire IT / enginering or other division, and will be gone before the inevitable rot and overages kick in? Accenture will happily do that for you, and figure out how to abuse the H1b program enough to fill as many bodies with offshore people in your onshore location as you need to justify your realestate purchase.

I genuinely think accenture might be one of the most powerful companies in the world, just because of how many entire departments of so many major internaional corporations actually report to accenture management, not the parent company.
