peter-senge and hal-hamilton co-founded the Sustainable Food Lab in 2002 as a cross-sector initiative applying systems-thinking-fifth-discipline and learning-organization principles to the challenge of making global food supply chains more sustainable. The Lab brought together an unlikely coalition of major food companies, NGOs, and government agencies — participants who were simultaneously competitors, critics, and collaborators — to address shared sustainability challenges that no single actor could resolve alone. This multi-stakeholder design made the Sustainable Food Lab an early and significant case study in the application of system-leadership to large-scale systemic change beyond the single-organization context where the five-disciplines had originally been developed.
The Sustainable Food Lab reflected the evolution in Senge's thinking that was also visible in presence-2004 and necessary-revolution-2008: a shift from organizational learning within firms to systemic change across sectors and supply chains. Where fifth-discipline-1990 addressed managers in corporations trying to transform their organizations, the Sustainable Food Lab addressed practitioners across sectors trying to transform systems that no one controlled. The tools adapted from the original framework — shared-vision across competing organizations, mental-models work in cross-sector dialogue, systems-thinking-fifth-discipline applied to supply chain dynamics — required significant adaptation for this more complex and contested environment.
The Lab operated as what Senge would later call a "learning lab for system leadership" — a place where the capabilities described in dawn-of-system-leadership-2015 could be developed through sustained practice rather than taught as abstract principles. hal-hamilton led much of the day-to-day work, and the Lab's evolution over two decades — expanding to include work on sustainable livestock, sustainable soybeans, and food system resilience — provided the empirical grounding for Senge and Hamilton's articulation of system leadership as a distinct practice requiring cultivation of specific inner capabilities alongside systems analysis skills.
