Saeed's recent post on the triumvirate of Sales, Marketing, and PM contains laudable suggestions for how PM can work better with these other groups. When he starts talking about the rocky relationship between Sales and Marketing, I worry that some hapless PM might read this post and think about playing peacekeeping force between these warring factions.

My frank advice: don't try to be the hero that ends the frictions between these two groups. At some point, they might ask you for help in some project that might help settle their differences. However, as in all troubled relationships, they must want to change for this sort of activity to be worthwhile. PM has enough challenges of its own, and it has little leverage or no over either of these organizations.
