It failed, and it failed miserably, and my former employer learnt a very expensive lesson. My colleagues in other investment banks reported similar stories in the 00s. That's far more than one data point.
Investment banks are not like other companies. They particularly enjoy writing their own code and systems, so when they tried to outsource and discovered that they weren't correct, or on time, they brought it all back in house.
> you just need to look at the revenue of Indian outsourcing companies, it keeps going up.
That's "pretty meaningless" without any data backing it - what's driving that revenue? Does Wipro, for example, publish its revenue figures for its IT outsourcing arm, and break that down further with key indicators? I can say with some confidence, that Goldman Sachs, JP Morgan, Citigroup, won't be the "drivers" of that revenue, and that's what the original article in this thread was talking about.

All the big IT Outsourcing companies are listed on the Indian stock exchanges, you can go to their sites and read the annual reports to see what is driving that revenue. Majority of their revenue comes from the US. Also check the share price of those companies for the last 20 years, where your bank failed, other succeeded in outsourcing their operations.
All the big IT outsourcing companies are publicly listed, you can go to their website and check their annual reports to see how their revenue is going up for. You can see the number of employees keeps going up, the number of clients keeps going up. All these figures are available for 20 years now.
Your one anecdote is pretty meaningless, you just need to look at the revenue of Indian outsourcing companies, it keeps going up.
