The Comparison
The same scope estimated two ways: a cross-functional Scrum team (6 people, no ART overhead, with discovery and hardening sprints) and a SAFe 6 Agile Release Train (10 FTEs, 1 PI). Even without ART ceremony tax, real-world team dynamics, ramp-up, and coordination keep the multipliers significant.

Application Scope
“One person with Claude Code shipped a production-ready 15,000-line platform in 3 days and ~8 human hours with zero meetings and zero documents, the same scope that a SAFe 6 enterprise team of 10 would spend 12 weeks, 593 person-hours of ceremonies, and $400K+ to deliver, proving that human-AI collaboration doesn’t just replace developers, it collapses the entire overhead structure of enterprise software delivery.”
