Product planning is a way to help your team (and other stakeholders) determine what will be included in future releases. Product planning should identify key business goals, should outline the high-level features that provide the most business value and have the highest priority, and should provide visibility into the project for all stakeholders, including executive sponsors, external teams (such as support, sales, or marketing), and team members.
Product planning is not meant to be exhaustive. Nor is it meant to be anti-Agile (by preventing team members from making the right decisions at the release and sprint levels). Some organizations need to be able to place the value of a product into other contexts, such as a budget or in comparison to other Agile teams within the organization.
