Hi Adnan,

Hope you are doing well !

In my opinion, YES, engineers can do business similar to a  BBA graduate. Though you would need some time to understand business, and it's concepts, unlike a BBA graduate, who is already aware of business and it's aspects.

However, once you understand the basics of business, such as sales, marketing, operations, finance, etc. you are good to go.

Thank you,

Hope the above answer was helpful.
