According to the PMBOK Guide and the Agile Practice Guide, Agile Release Planning is a collaborative process used to determine how many iterations (sprints) will be required to deliver a functional product increment. This planning provides a high-level summary timeline that is driven by the broader strategic goals of the project.
* Product Vision: The product vision is the " north star " of the project. It defines the long-term goal and the " why " behind the project. Every release must align with this vision to ensure the team is building the right product.
* Product Roadmap: The roadmap is a high-level visual summary that maps out the evolution of a product over time. It shows the sequence of features and major milestones. Agile release planning takes the goals defined in the roadmap and breaks them down into specific releases.
* Strategic Alignment: While iterations and story points are used to measure progress during the planning session, the basis or foundation of the release schedule itself is derived from the high-level roadmap and the overarching vision established by the Product Owner and stakeholders.
Why other options are incorrect:
* Option A: Activities and story points: Story points are a unit of measure for effort, and activities are more common in predictive scheduling. While story points help determine velocity, they do not provide the high-level " summary timeline " logic that the roadmap provides.
* Option B: Iteration and prioritization plans: Iteration planning (sprint planning) is a low-level, detail- oriented ceremony that happens at the start of each sprint. Release planning is at a higher level and encompasses multiple iterations.
* Option D: Tasks and user stories: Tasks are the most granular level of work (often tracked on a Kanban board). User stories are the backlog items. Planning a release timeline based only on individual tasks would be too " bottom-up " and would lack the strategic context provided by the roadmap.
