Overview
"Why the Lean Start-Up Changes Everything" is a Harvard Business Review cover story published in May 2013. Written by Steve Blank, it brought the Customer Development/Lean Startup methodology to the mainstream business audience — moving it from Silicon Valley startup culture into the broader management conversation.
Key Arguments
The article argued that:
Impact
The HBR publication was a watershed moment for the methodology's mainstream acceptance. HBR's audience — corporate executives, MBA students, management consultants — was fundamentally different from the startup practitioners who had adopted Customer Development through "Four Steps" and Ries' "Lean Startup." The cover story legitimized the methodology for corporate innovation, not just startup founding.
Significance
The article marks the moment when Customer Development/Lean Startup crossed from startup subculture into mainstream business thinking. It is the most widely read single articulation of the methodology.
