Do they get repeat business? Also, are American engineers that use their work being pressured to frame the collaboration as a success? When a VP's bonus depends on his ability to show cost savings through offshoring, you can bet the managers under him will find some way to patch up the code stateside and declare the project a success. The official proclamations of success create good word-of-mouth for the contract company, so they get more business. I've seen this happen firsthand, not with offshoring to India, but with developers being forced to work with an American consulting firm that their executive happened to trust more than his own staff.
