Two organizations may enter into a contractual agreement involving an exchange of services and payments. Outsourcing is said to help firms to perform well in their core competencies and mitigate shortage of skill or expertise in the areas where they want to outsource.[5]
In the early 21st century, businesses increasingly outsourced to suppliers outside their own country, sometimes referred to as offshoring or offshore outsourcing. Several related terms have emerged to refer to various aspects of the complex relationship between economic organizations or networks, such as nearshoring, crowdsourcing, multisourcing[6][7]and strategic outsourcing.[8]
Outsourcing can offer greater budget flexibility and control. Outsourcing lets organizations pay for only the services they need, when they need them. It also reduces the need to hire and train specialized staff, brings in fresh engineering expertise, and reduces capital and operating expenses.[9]
