The foundational configuration and starting point for almost every adoption — the Agile Release Train, PI Planning, core roles, and the basic Lean-Agile practices needed to deliver value through one train. Implement only this and you still capture most of the benefit.

Best for: a single ART, or organizations just beginning to scale.

Adds the coordination layer for solutions too big for one train — complex systems in aerospace, defense, automotive, or large platforms. Introduces the Solution Train to synchronize multiple ARTs and suppliers toward one large deliverable.

Best for: big, multi-ART solutions where engineering complexity — not funding — is the challenge.

Connects strategy to execution. Adds Lean Portfolio Management — Lean budgeting, portfolio strategy and funding, and lightweight governance — so the trains’ work aligns to strategy and is funded as flowing value streams, not fixed annual projects.

Best for: aligning delivery with strategy and modernizing how work is funded.

The most comprehensive configuration — combines team, program, large solution, and portfolio. Used by the largest enterprises building big solutions that also need portfolio-level strategy and governance.

Best for: large organizations where both solution complexity and strategy alignment must be solved together.
