When should I use the tense “has been”?

Question

I’m a non-native speaker but I work for a multinational company so I have to use English 95% of the time at work.

I find myself using has/have been a lot simply because it sounds right to me.

As an I example, I have to report on a status of a task/project. When should I use the below sentences?

• The project is completed.
• The project has been completed.

Answer 1

He has/she has/they have been to the shops – as a native speaker it would likely be contracted to he’s/she’s/they’ve been to the shops.
