COSMIC has an active community of volunteers, working together to advance the COSMIC method. There are a number of permanent committees:
- International Advisory Council (IAC) is the advisory board for the Executive Committee. The IAC consists of representatives of COSMIC to over twenty countries
- Measurement Practices Committee (MPC) is the guardian of the principles and rules of the COSMIC method
- Certification Committee is responsible for creating, organizing and overseeing the COSMIC certification exams
- Education Committee is responsible for developing university training material
- Benchmarking Committee organizes and promotes the collection of COSMIC data for the independent ISBSG database
- Marketing Committee is responsible for the promotion of the COSMIC method, with the aim of ensuring its successful adoption worldwide
- Interactive Media Committee maintains all media that is used to distribute and promote the COSMIC method
Next to the permanent committees there are a number of ad hoc teams to create specific products, like guides or case studies.
