Overview
Mission
Educational: the ISSS provides membership benefits in the form of systems education publications and annual meetings for its membership and other interested researchers. We host educational learning sessions online throughout the year so researchers can meet and share their work to further the field of systems science. Our aim is to research the field of systems science and provide educational opportunities to share the findings.
What it reported doing in 2025
This year the ISSS worked to serve the membership and the systems community at large by holding an in person annual meeting attended by over 90 people in person and 90 people online. ISSS has also continued to increased its options for members to collaborate and participate online by using meeting platforms and opportunities. This year the ISSS provided an opportunity for members to contribute to the theme of advancing together across the systems science field. ISSS currently has an overall membership of 130 people. Due to the success of our online presence, it was decided to continue to include online program options to increase accessibility for members and the organization. The ISSS also published an extensive conference proceedings that capture the research and collaborations of the year. The organization also created a number of recorded videos of many of the presentations, sessions and conversations that took place over the year and attended by members and non members from around the world.
Operating model
- Revenue model
- Earned-program. 77% of the money available for current operations came from fees and other program revenue.
- Distribution model
- Direct operator. The filing allocates 100% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.
The verdict
STRONG - A large share of available resources goes toward mission work and the filed numbers largely add up. Revenue has declined or grown slowly and reported officer compensation is a large share of total spending, which may reflect staffing concentration.
