Outsourcing is giving a piece of work to an outside team of your organization to complete. In the software and web development world, many of us have heard of outsource channels like India, who promise highly educated programmers at very low costs.
There have been many problems with outsourcing to off-shore teams in the past, the major ones being communication issues, and lack of control. Very often projects which would have taken 100 hours to complete locally suddenly take 300 hours off-shore. This takes a significant bite out of the savings in outsourcing to begin with, and if this means you need to chain on another project manager to deal with the off-shore teams, then your savings are pretty much gone. You may as well just save yourself the headache and develop in-house right from the start.
There is a very significant and obvious problem shared with just about all failed off-shore projects: They all failed to plan correctly. The solution to effective outsourcing is proper and detailed specifications. Once you have a spec that leaves absolutely nothing to the imagination, developers have no choice but to deliver what you asked for.
Due to population of India. Outsourcing work is easy. & according to my point of view in this scenario every company is facing lots of competition, to his competitor so its not very easy to delay the project timing.
