I'm guessing you mean - how do you use the word* "ideation" in a sentence.
Here goes:
Ryan has the ability to harmonize strategic ideation with tactical execution.
she played an important role in ideation level
I had to talk to him about his work.
Describe what is your " work ethic"
edit your work
I was inpress by your work.
I work very hard.

It depends how you use it. If you use it after something it can be correct. But being in a sentence by itself isn't correct.
Example sentence - His missionary work was great.
She work erratically.
i will complete my work
His work of art was praiseworthy.
