If you rely too much on the people in other countries and other companies, in a sense that's your brain and you are outsourcing your brain.
Outsourcing and globalization of manufacturing allows companies to reduce costs, benefits consumers with lower cost goods and services, causes economic expansion that reduces unemployment, and increases productivity and job creation.
The other part of outsourcing is this: it simply says where the work can be done outside better than it can be done inside, we should do it.
If you deprive yourself of outsourcing and your competitors do not, you're putting yourself out of business.
In the long run, outsourcing is another form of trade that benefits the country's economy by giving us cheaper ways to do things.
The important thing about outsourcing or global sourcing is that it becomes a very powerful tool to leverage talent, improve productivity and reduce work cycles.
