This is why outsourcing fails. Generally, outsourced developers will just implement exactly what the spec says to implement, no more and (hopefully) no less. You can't communicate with them synchronously and answer their questions in real time because they're located on the opposite side of the earth. Time is money and waiting for your answers would be too expensive, so they just don't ask questions, instead they make guesses and assumptions about anything you haven't clearly specified. Then you slowly realize that it takes about as much time and effort to write a comprehensive, detailed specification of the software, as it does to actually write the software itself.
