How do Features and Capabilities in a large Solution interact?

In the context of SAFe (Scaled Agile Framework), Features and Capabilities are critical components that facilitate the hierarchical structure of requirements in a large solution. The correct option asserts that every Feature has a parent Capability, which speaks to the structured relationship between these two elements.

In large solutions, Features represent specific functionalities that deliver value to the users, while Capabilities are broader competencies that embody the higher-level functionality necessary to realize a large solution's goals. By design, every Feature must align with and stem from a Capability that provides the context and framework within which that Feature operates. This ensures that all Features contribute to the overall objectives and strategic vision embodied by the Capability.

The hierarchy aids in maintaining clarity across teams and aligning work to business objectives, ensuring that all development efforts are purposeful and contribute to a cohesive solution architecture. This organized approach prevents the development of Features that are misaligned with larger strategic goals, thus promoting efficiency and reducing wasted effort.

While there may be instances where some Features could exist without parent Capabilities, this would typically not adhere to the structure laid out in SAFe, hence reinforcing why every Feature is tied to a Capability. Moreover, Capabilities often have multiple Features, making the relationship expansive rather than limited, and they function as the guiding
