Though I'm of the dilbert opinion that whenever somebody from marketing gets involved you can see the cracks forming in the building walls.
It's more when non-experts get to have their opinion about something they don't fully understand of have had little experience of. Their knowledge is often inversely proportional to the stridency of their view, so you spend a lot of meeting time rubbing your temples and thinking how can you best explain the flaws in their reasoning in a way that won't make them out to be be the dropkick that they actually are and generally wishing you'd never invited them, as you know if you had competent developer or an interface designer it would be a 30 second conversation and then you'd move on
