One thing that bothered me about this was the choice of pronouns for the two roles. Probably, its more likely that a product manager is female, and an engineering manager is male, but wouldn't it have made just as much sense using neutral pronouns?
This is always a no win situation. I am actually a male product leader and it was written by a female product leader. It is much easier to write (and read) with a "he" of "she" vs "they." We are sensitive to this issue and do our best to mix the pronouns in posts. Thanks for the comment.
