What we need to consider if additional roles are needed above trains?

• A. The salary bands for all staff
• B. Number, scope and dependencies of the trains
• C. Geographic distribution of teams
• D. Technology stack used

Answer: (B)

Coordinating multiple Agile Release Trains requires looking at three things: how many trains you have, what the overall solution they deliver covers (the scope), and how much they depend on each other. When there are several ARTs that share components or require joint architecture and integration, you typically need higher-level coordination—often forming a Solution Train with roles and governance to align the trains’ work, roadmap, and program increments. This higher structure helps manage cross-ART dependencies, synchronize PI planning, and ensure a cohesive release of the larger solution. If you only have a single ART or multiple ARTs with little interdependence, you may avoid creating a formal Solution Train and rely on existing ART roles for alignment. The key is that the number of trains, the breadth of the solution, and the dependencies between trains drive whether extra coordination above the trains is necessary.
