Which role accepts Capabilities as complete?

The role that accepts Capabilities as complete is Solution Management. In the context of SAFe, Solution Management is responsible for defining and validating the Capabilities that will meet customer needs and drive business value. This role plays a crucial part in the larger context of the Solution Train, ensuring that the overall solution aligns with strategic objectives and meets quality standards.

Solution Management engages with stakeholders, gathers feedback, and assesses whether the Capabilities developed by various Agile Release Trains (ARTs) fulfill the defined acceptance criteria. Their acceptance signifies that the work done aligns with the requirements and can effectively deliver the intended value to customers.

Other roles, such as Product Management, typically focus on defining features and requirements within a single ART rather than across the broader solution. Solution Architects/Engineers provide technical guidance and ensure architectural integrity but do not typically make decisions about accepting Capabilities. Solution Train Engineers facilitate the processes and coordination within a Solution Train, but they do not hold the authority to declare Capabilities as complete. Therefore, Solution Management is the appropriate role for this responsibility.
