For years the model was simple, and quietly broken. Product built the thing, threw it over the wall, and marketing worked out how to sell it. Everyone knew it wasn't working. Nobody had a better structure to put in its place. That's what this session is for. It pulls apart what a genuine PM/PMM partnership looks like in practice: where the two roles overlap, where they absolutely shouldn't, and how to redraw the line without waiting for a reorg to do it for you. Expect real operating detail on shared inputs, joint customer evidence and a single agreed definition of a successful launch, rather than a diagram of how things ought to work. Key learnings: - A clear ownership map across discovery, launch and post launch, so nothing falls between the two roles - How to build a shared launch definition that both teams are measured against - The conversation to have with your PM counterpart on Monday morning, and how to open it
