Design a comprehensive systems thinking approach for analyzing and addressing complex, multi-stakeholder problems. Your response should cover: 1) Causal loop diagram construction methods, 2) System archetype identification and intervention strategies, 3) Leverage point analysis and prioritization, 4) Mental model examination techniques, 5) Boundary specification and critique, 6) Time horizon considerations in system dynamics, 7) Feedback mechanism identification (balancing and reinforcing loops), 8) System resilience versus optimization trade-offs, 9) Intervention point selection and resistance anticipation. Provide concrete examples of applying these methods to specific complex challenges like urban planning or healthcare delivery, including how to facilitate stakeholder understanding of systemic thinking approaches.
