As a SAP Consultant that worked on SAP Utilities software....
This is a specialized field. Only a handful of firms did this, including one I worked for in the US (Axon Global now sucked up by ATOS in the US). I also worked at Wipro on a very large account so I know a bit about both.
Wipro is a cheap alternative but you get what you pay for. They do have some good staff but they don't pay very well and as it's an overseas firm, not too many US workers, at least by comparison with the more expensive consultancies. That leads to a fair bit of turnover among the US workers especially when it's discovered that raises don't exist for the most part and greener pastures beckon. Much like IBM, really...
Much of my knowledge is of Wipro/Tata/et alios ad nauseam being brought in after either a budget cut by the client or as maintenance partners after implementation, so it's not quite fair to castigate them when IBM/PW and others (Accenture!) have has massive lawsuits due to much the same claims.
I did notice that Wipro tended to try to work with clients more flexibly than the US Big 4, it seems half the reason for some of the low estimates was to bill out fully on anything not explicitly named. (change Orders = Big Bux, dammit!) But I'm having a hard time seeing how the client allowed this stuff without testing. From the sound of it, some of these should have been caught in QA. So it's far more likely that some of this goes back to the client.
