Outsourcing has become a well known and commonly used strategy for Swedish companies, which involves buying a part or process from a subcontractor rather than performing it within the company. Common reasons why companies chose to outsource rather than to perform the activities themselves are cost- and competition related. Previous low labour- and facility costs in countries such as China and Estonia have been forces that have kept the outsourcing trend strong. In recent years you can see more Swedish companies bringing back previously subcontracted functions into the company, so called insourcing. This can partially be explained by changes in external market factors such as raising salaries in low-cost countries and increased automation.
