Simply put, BA is similar to the position of PM (product manager), which is the abbreviation of English word (BusinessAnalys), that is, business requirements analyst.

In IT companies, the role of BA is PM (product manager), but this kind of PM has to undertake a very specific business or field.

For example, a bank also has its own IT department, and the product manager in the IT department of the bank may have to connect with special business groups, such as online banking, credit card business, wealth management products business and fund agency business, so the product manager who undertakes a specific business demand is called BA.
