What is the primary function of a Solution Train in SAFe?

The primary function of a Solution Train in SAFe is to coordinate multiple Agile Release Trains (ARTs) and suppliers for the development of large solutions. This is essential in the context of complex systems that require the contributions of multiple teams working in tandem to deliver integrated and cohesive value.

A Solution Train facilitates the alignment of various ARTs, ensuring collaboration among them and with external suppliers, enabling them to work together toward a common goal. It manages dependencies, integrates components, and ensures that all parts of the solution fit together effectively. This collaboration is beyond what a single ART can achieve, as it deals with larger, more intricate solutions requiring broader coordination.

In this context, the other options do not capture the full scope of a Solution Train’s role. Delivering individual components independently is not aligned with the collaborative essence that a Solution Train promotes. Managing the day-to-day operations of a single ART is focused on a more limited scope and does not encompass the full coordination role. Similarly, evaluating team performance metrics alone fails to address the need for cross-team alignment and integration, which is central to the mission of a Solution Train.
