When the product backlog has grown, the product owner needs to arrange the backlog into two sections:
- Near-term items: Near-term items need to be fully fleshed out before they are labeled as such. This means that they are complete with user stories, collaboration with design and development has been sorted out, and estimates from development have been prepared.
- Long-term items: Longer term items can be less detailed, it is still a good idea to get a rough estimation from the development team on these tasks, so that they can be prioritized. Emphasis lying on the word "rough": estimates will change once the team fully understands and begins work on those longer term items.
