Organisations that implement SAFe at team and ART level without changing the portfolio layer tend to hit the same ceiling. Funding stays annual. Governance stays project-based. Strategy doesn't reach the teams doing the work. The ARTs run PI Planning, but the decisions that matter — what to fund, what to stop, how to respond to change — still happen the same way they always did.
Lean Portfolio Management is where that changes. It's also where implementations most commonly stall, because the people who need to change their behaviour are senior leaders, and changing leadership behaviour requires more than training.
Em Campbell-Pretty and Adrienne Wilson are SAFe Fellows, SPCTs, and the authors of The ART of Avoiding a Train Wreck — the book on what goes wrong in SAFe implementations and how to prevent it. That pattern recognition is what they bring to every LPM engagement.
