Product vision is the long-term picture of the future you're trying to create; product strategy is your coherent plan for getting there — where to play and how to win given limited resources. Strategy is fundamentally about choices and focus: deciding what to do, and just as importantly, what not to.
Vision vs. strategy vs. roadmap
VISION → the destination ("why we exist; the future we want")
STRATEGY → the path ("which problems, which users, how we win")
ROADMAP → the near-term steps ("what we're building now/next")
