This process is based as a fundamental pillar on changing the company's processes in aspects such as culture, procedures, systems, controls and technology, whose objective is to obtain better results, concentrating all the company's efforts and energy on the core business.

Outsourcing can also be defined as a process that seeks to streamline and economise production processes for the efficient fulfilment of the company's objectives, so that companies can focus on their core business.

Financial department.
Technical department.

Information systems departments.
Logistical processes.
Production processes.
Secondary sales and distribution processes.
Supply processes.

Some company processes that should not be outsourced (of course, there are exceptions to be considered):

Strategic planning: that which is the management decision of the company's ship.
Treasury: the company's money and its management should not be left to a third party, as cash needs are fundamental to the company's viability.
Supplier control: controlling suppliers is controlling your purchasing and merchandise needs.
Quality management: quality is the value-added service a company provides.
Customer service: the face of the company, how the customer feels about the company.
Distribution and sales: sales are the core of the company, as they are what the company lives from.

Outsourcing comes from the English words: out and sourcing, out is out and sourcing is the act of transferring work, responsibilities and decision making to someone else.
