People often assume that when something goes on the product roadmap, that the team has every intention of building and launching this.
This article explain why it’s a good idea to reposition the roadmap as the “opportunity backlog.”
The opportunity backlog is the prioritized set of opportunities for the product discovery team to explore in product discovery. The output of product discovery is the product backlog, which is the prioritized set of work (usually represented as user stories and prototypes) for the delivery team.
The opportunity backlog will help you to keep your product backlog “clean” and to focus on opportunity assessments. It is a great tool for Product Owners and UX designers.
