Abstract
Background/Problem: The pursuit of health and well-being is consistently challenged by complex, interconnected barriers that defy siloed solutions. A persistent gap exists between technical interventions (tangible, procedural) and adaptive insights into human behaviour, culture, and relational dynamics. This disconnect leads to interventions that are either technically sound, but culturally misaligned, or empathetically designed but structurally unfeasible, undermining sustainable progress in areas from Universal Health Coverage to individual behaviour change.
Solution: To bridge this divide, we introduce the PEACE Framework, a dual-purpose methodology designed to integrate technical and adaptive dimensions. The framework conceptualizes these as "T- shaped" challenges, where the horizontal bar represents broad Technical problems and the vertical stem signifies profound Stem (adaptive, human-centered) drivers.
Operational Tool: The framework is operationalized through the PEACE Model Canvas (PMC), a one- page visual tool that guides users through five iterative, participatory stages: Problem Identification, Excavation of the Root Causes, Analysis of Consequences, Consideration of the Prerequisites for Change, and Execution of the Change Plan. Each stage applies a dual analytical lens, Technical (data- driven) and Stem (adaptive, cultural), to promote integrated solutions.
Demonstrated Utility: The evidence presented is primarily observational and practice-based. The PMC was developed and refined through application in Zambia to address a devastating adolescent health syndemic. By enabling multi-sectoral stakeholders to visually map both technical drivers (e.g., stockouts) and stem drivers (e.g., stigma, fragmented communication), the tool facilitated co-created, dual-track strategies that improved coordination and community engagement.
Conclusion: The PEACE Framework and PMC offer a structured yet flexible methodology for developing interventions that are both evidence-based and contextually resonant. They equip practitioners to navigate complexity by unifying diagnostic rigor with participatory design, advancing equitable and sustainable change across system and individual levels.
