An IT outsourcing strategy can require input from many departments, including operations, legal, supply chain and human resources. The responsibility for the outcome of an IT outsourcing strategy, however, usually lies with the organization's chief information officer (CIO). For many organizations, the goal of an IT outsourcing strategy is to provide the best possible technology to the organization at the lowest possible cost. What constitutes the best possible technology and lowest cost, however, tends to be fluid due to rapidly evolving technologies and market volatility. Cost savings, however, is not the only aim of an IT outsourcing strategy. Some organizations looking for business transformation rely on outsourcing providers to help them through the process. Even on this front, IT outsourcing strategy is changing. Whereas in the past organizations often used one large IT service provider to handle the entire project, outsourcing strategists today recommend taking a multi-vendor approach.
