Traditionally, companies have outsourced for tactical reasons - reduce costs, free up cash, obtain resources not available internally, and improve their performance. Outsourcing can enhance a company's ability to manage costs more effectively. If a company is moving into a new arena, outsourcing enables it to add new functions with minimal impact on internal resources. Organizations today also approach outsourcing as a business strategy.

Outsourcing allows customers to realign resources so they can focus on their core competencies. Customers need not worry about day-to-day technology operations support. Their entire operations function at a high level, yet they do not have to maintain everything. They get world-class capabilities without the risks involved in developing all of them.

You are able to use specific skills (for particular technologies) for a certain period without having to hire them or train them. Even if you think that you could retrain the team you already have you should take into account that you could have a better one working on your project in a much smaller time-frame.
