Should I say focus in or focus on. In which situations is better to use one over the other.

I need to focus on/in quality issues.


You use the preposition "on", not "in", after the verb "focus" when you give a lot of or particular attention to somebody or something,

So the correct sentence is:

I need to focus on quality issues.
