When to use "cross-functional" or "cross-functionally"? [closed]

I am trying to find an answer as to how to use the compound word "cross-functional" correctly to describe working with a team from different departments.

I collaborated with a cross-functional team of six interns in building project goals and ideas.

or do I use "cross-functionally" instead?

I collaborated cross-functionally with six interns in building project goals and ideas.

If both sentences are correct, is it more on preference and style? I have researched both usages, but I need more clarity since English is not my first language.

Solution 1:

Cross-functional is an adjective. It's the way you are describing something e.g. "I used to work with cross-functional teams."

Cross-functionally is an adverb i.e. it describes the verb e.g. "I used to work cross-functionally."

Both are correct and can be used based on the context.
