A basic understanding of them, 
Then go over the top 10 differences between outsourcing and offshoring, 
And lastly, discuss the key factors to keep in mind while choosing between them.
Understanding of Outsourcing & Offshoring
Outsourcing, at its core, means you are hiring third-party services to complete a piece of work or a whole project, which involves delegating specific tasks or services to external companies, often to harness specialized expertise or reduce costs. 
For example, Google outsources IT management to firms in India, and Nike outsources manufacturing to factories in Vietnam and China.
Offshoring means you are relocating your business operations to other countries frequently where labor costs are lower like India and China to emphasize geographical cost advantages and talent pools. 
For instance, Apple offshores its manufacturing to China, and Wells Fargo offshores customer service to India and the Philippines.
Evolution of Outsourcing
Outsourcing began during the Industrial Revolution in the 18th century when businesses started contracting out non-core activities to outside experts with a view of improving efficiency.
First, it was limited to simple clerical work such as accounting, but, in the late 20th century, outsourcing expanded with the emergence of Business Process Outsourcing (BPO), which also includes more complex service activities such as call center and IT support.
Evolution of Offshoring
Offshoring started to gain momentum in the 1980s and the 1990s due to enhanced telecommunications and the Internet. From then, most developed Western firms started relocating manufacturing and IT services to developing countries like India and China. So, you can mark this era as the start of a new global economy, where geographic boundaries became less relevant to scale businesses.
