ABSTRACT
This study explores the intersection of longevity planning, service systems, and financial planning to enhance our understanding of longevity planning at the service system level and offer insights into building longevity service systems. This study adopts Vink and Koskela-Huotari’s iceberg framework for an extensive literature analysis, viewing social structures as materials for service design to shape the research question: What are critical design considerations for physical components (symbols, artifacts, activities, relationships) and institutional elements (regulative, normative, cultural-cognitive pillars) within social structures for developing comprehensive, meaningful longevity service systems? The aim is to formulate comprehensive design recommendations by integrating insights from diverse disciplines based on social structures. The study conducted an extensive preliminary literature review using the modified PRISMA checklist, focusing on the most cited 100 peer-reviewed articles from 2019 to 2024 within the USA. Keywords such as longevity planning, design for longevity, and systemic service were used. After an initial review of titles and abstracts, selected papers and gray literature underwent full-text analysis. Ultimately, 30 papers met the inclusion criteria for systematic review. Integrating the insights from the systematic review and iceberg framework, this study contributes by offering holistic considerations for the design and development of longevity service systems.
