  Research software plays a crucial role in advancing scientific knowledge, but
ensuring its sustainability, maintainability, and long-term viability is an
ongoing challenge. To address these concerns, the Sustainable Research Software
Institute (SRSI) Model presents a comprehensive framework designed to promote
sustainable practices in the research software community. This white paper
provides an in-depth overview of the SRSI Model, outlining its objectives,
services, funding mechanisms, collaborations, and the significant potential
impact it could have on the research software community. It explores the wide
range of services offered, diverse funding sources, extensive collaboration
opportunities, and the transformative influence of the SRSI Model on the
research software landscape
