This seems like it's really narrowly focused on the software developers' part of an agile project's lifecycle. And I agree, within that scope, you should absolutely shut up and plan the sprint. Product strategists, though, can't afford to be so shortsighted. And most companies don't (and maybe shouldn't) have such a clear separation of roles. I've found that, when your job involves wearing multiple hats, the trick is to pay attention to what hat you're wearing at any given moment. Don't let them all get muddled up. When it all blends together, then the smallest unit available to you to boil is the whole ocean.
