A public roadmap is your product direction shared externally with customers. It typically shows three states: planned, in progress, and shipped. Users can see what you're building, understand why a requested feature is a few cycles out, and feel informed rather than ignored.
The practical benefits are real. It cuts down "is this on your roadmap?" support tickets, helps prospects make purchase decisions, and signals that you're confident in your direction.
A public roadmap is a statement of intent, not a contract. You don't need hard dates on everything. "Planned" is honest. "We're considering this" is honest. What's not honest is telling prospects a feature ships in 60 days when you don't actually know.
Only put things on a public roadmap that you've committed to investigating or building. Speculative ideas belong in an internal backlog. Vague is fine. Wrong is damaging.
A well-run public roadmap also creates a feedback loop. Customers vote, comment, and surface use cases you hadn't considered. It turns a one-way announcement into a conversation. Teams that avoid public roadmaps usually aren't protecting strategy. They're avoiding accountability.
