You think "Here is a pressing question some people in my field have encountered..." and, for something like this, you likely contact the editorial office to make sure it's of interest. Or you submit to a journal that has a consistent track record of publishing papers on the practice of their subject.

Having been a reviewer on similar types of papers - once the editor has decided it may be of interest you read it over, make sure you think the content is accurate and it will be of interest, make any comments you might have, and submit your review. Other times, the review is internal.
