In 30 seconds
- Coordinates multiple ARTs and suppliers in a Solution Train.
- Adds solution-level roles, backlog and events.
- For systems like aircraft, medical devices or large platforms.
When it's needed
When one Agile Release Train can't build the whole solution, such as complex cyber-physical systems, SAFe adds a solution level to coordinate several trains and suppliers.
What it adds
- The Solution Train
- Solution Train Engineer, solution management and solution architect
- A solution backlog of capabilities
- Solution-level planning and demos
Trade-offs
Large Solution SAFe handles real complexity, but each layer adds coordination overhead. Use it only when the solution truly can't be split into independent products.
