What are different views of a Product Backlog?

The different views of a Product Backlog include Program, Solution, and Portfolio Backlogs, which reflects the hierarchical structure commonly found in scaled Agile frameworks.

A Portfolio Backlog encompasses epics and high-level initiatives that may span multiple programs and align with the strategic vision of the organization. It provides visibility at the organizational level, ensuring that priorities reflect the overarching business goals.

A Program Backlog is more focused and pertains to a specific program within the organization. It contains features and capabilities that drive value for a particular set of teams working together, allowing for a coordinated approach to delivering the program's objectives.

The Solution Backlog focuses on the components needed to deliver a complete solution, which may involve multiple programs. It helps in managing the complexity of developing and integrating various components to ensure they work together effectively.

This structured approach allows organizations to better manage their backlog at different levels, ensures alignment with strategic goals, and emphasizes the delivery of value through structured prioritization across various scopes of work. In contrast, the other options mentioned generally reflect a narrower or less formalized view of the backlog hierarchy.
