Hi there, the template you need will depend on your product and type of company you work for. Can you provide a bit more information so I can put a good answer together for you?
Just answered a similar question which you can find here:
We use our own product,, which automatically produces our roadmaps as we move prioritized features from our customer base & internal teams into “Planned”. Really easy process & super efficient due to the automation. Exactly what we need due to the scale we operate on.
Totally depends if you are looking for a full solution or simple way to throw a roadmap together. I’ve used all sorts before from spreadsheets and project management tools to what we have today. Use what’s best for you!
