The next wave of outsourcing is about assessing all aspects of an organization's business activities to determine if and where there are opportunities to leverage outsourcers' capabilities, intellectual property, best practices, global infrastructure or geographic presence to access resources and capabilities around the globe.
Most companies have outsourced some portion of their business to lower costs and, over time, have achieved cost savings in the outsourced portion of the business.
Unless your efforts in outsourcing to lower costs are unusually good, you are not gaining a sustainable competitive advantage, since your competitors are outsourcing just like you are.
