What is a product?
In ProdPad, there is a one-to-one relationship between a product and a roadmap. That is, in order to have one, you have to have the other.
If you aren't quite sure if you need more than one product, ask yourself - is the strategy different enough from one component to the other that you require a separate space for each? If the answer is yes, you've got more than one product! (If you're having trouble figure that out, book a roadmap clinic with us!)
Rather than having a product and roadmap for each delivery team, focus your product and roadmap on your customers. Does your roadmap tell a cohesive story which describes how your customers will see value from your product? If they need more information, you may be too granular in your approach. If there is too much information, you may need to break things down a little more
Depending on the size of your portfolio, you may have a single product, or a variety of products within product lines - each with their own canvas, roadmap, and documentation to make sure everyone in your team understands the overall vision and direction of the product.
