Product Development and Product Marketing - What's the Impact of Information Silos on Product Development?

Product and product marketing are two areas that can be affected by information silos. One of the biggest things is just planning doesn't happen, right? So when there's this kind of flaming bag pass where product is like, hey, we built a thing, we're going to launch it next week...you don't have any time to build out your version of product. And so you end up getting this outcome where other teams just flop in their execution around the launch.
